ID CVE-2009-1895
Summary The personality subsystem in the Linux kernel before 2.6.31-rc3 has a PER_CLEAR_ON_SETID setting that does not clear the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags when executing a setuid or setgid program, which makes it easier for local users to leverage the details of memory usage to (1) conduct NULL pointer dereference attacks, (2) bypass the mmap_min_addr protection mechanism, or (3) defeat address space layout randomization (ASLR).

Third-party library update for ntp. The Network Time Protocol (NTP) is used to synchronize a computer's time with a referenced time source. ESXi 3.5 and ESXi 4.0 have a ntp client that is affected by the following security issue. Note that the same security issue is present in the ESX Service Console as described in section d. of this advisory. A buffer overflow flaw was discovered in the ntpd daemon's NTPv4 authentication code. If ntpd was configured to use public key cryptography for NTP packet authentication, a remote attacker could use this flaw to send a specially crafted request packet that could crash ntpd or, potentially, execute arbitrary code with the privileges of the 'ntp' user. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-1252 to this issue. The NTP security issue identified by CVE-2009-0159 is not relevant for ESXi 3.5 and ESXi 4.0. d. Service Console update for ntp Service Console package ntp updated to version ntp-4.2.2pl-9el5_3.2 The Network Time Protocol (NTP) is used to synchronize a computer's time with a referenced time source. The Service Console present in ESX is affected by the following security issues. A buffer overflow flaw was discovered in the ntpd daemon's NTPv4 authentication code. If ntpd was configured to use public key cryptography for NTP packet authentication, a remote attacker could use this flaw to send a specially crafted request packet that could crash ntpd or, potentially, execute arbitrary code with the privileges of the 'ntp' user. NTP authentication is not enabled by default on the Service Console. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-1252 to this issue. A buffer overflow flaw was found in the ntpq diagnostic command. A malicious, remote server could send a specially crafted reply to an ntpq request that could crash ntpq or, potentially, execute arbitrary code with the privileges of the user running the ntpq command. The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2009-0159 to this issue. e. Updated Service Console package kernel Updated Service Console package kernel addresses the security issues listed below.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-2692, CVE-2009-2698 to the security issues fixed in kernel 2.6.18-128.7.1. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-0745, CVE-2009-0746, CVE-2009-0747, CVE-2009-0748, CVE-2009-2847, CVE-2009-2848 to the security issues fixed in kernel 2.6.18-164. f. Updated Service Console package python Service Console package Python update to version 2.4.3-24.el5. When the assert() system call was disabled, an input sanitization flaw was revealed in the Python string object implementation that led to a buffer overflow. The missing check for negative size values meant the Python memory allocator could allocate less memory than expected. This could result in arbitrary code execution with the Python interpreter's privileges. Multiple buffer and integer overflow flaws were found in the Python Unicode string processing and in the Python Unicode and string object implementations. An attacker could use these flaws to cause a denial of service. Multiple integer overflow flaws were found in the Python imageop module. If a Python application used the imageop module to process untrusted images, it could cause the application to disclose sensitive information, crash or, potentially, execute arbitrary code with the Python interpreter's privileges. Multiple integer underflow and overflow flaws were found in the Python snprintf() wrapper implementation. An attacker could use these flaws to cause a denial of service (memory corruption). Multiple integer overflow flaws were found in various Python modules. An attacker could use these flaws to cause a denial of service. An integer signedness error, leading to a buffer overflow, was found in the Python zlib extension module. If a Python application requested the negative byte count be flushed for a decompression stream, it could cause the application to crash or, potentially, execute arbitrary code with the Python interpreter's privileges. A flaw was discovered in the strxfrm() function of the Python locale module. Strings generated by this function were not properly NULL-terminated, which could possibly cause disclosure of data stored in the memory of a Python application using this function. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2007-2052 CVE-2007-4965 CVE-2008-1721 CVE-2008-1887 CVE-2008-2315 CVE-2008-3142 CVE-2008-3143 CVE-2008-3144 CVE-2008-4864 CVE-2008-5031 to these issues. g. Updated Service Console package bind Service Console package bind updated to version 9.3.6-4.P1.el5 The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly. A flaw was found in the way BIND handles dynamic update message packets containing the 'ANY' record type. A remote attacker could use this flaw to send a specially crafted dynamic update packet that could cause named to exit with an assertion failure. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-0696 to this issue. h. Updated Service Console package libxml2 Service Console package libxml2 updated to version 2.6.26-2.1.2.8. libxml is a library for parsing and manipulating XML files. A Document Type Definition (DTD) defines the legal syntax (and also which elements can be used) for certain types of files, such as XML files. A stack overflow flaw was found in the way libxml processes the root XML document element definition in a DTD. A remote attacker could provide a specially crafted XML file, which once opened by a local, unsuspecting user, would lead to denial of service. Multiple use-after-free flaws were found in the way libxml parses the Notation and Enumeration attribute types. A remote attacker could provide a specially crafted XML file, which once opened by a local, unsuspecting user, would lead to denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-2414 and CVE-2009-2416 to these issues. i. Updated Service Console package curl Service Console package curl updated to version 7.15.5-2.1.el5_3.5 A cURL is affected by the previously published 'null prefix attack', caused by incorrect handling of NULL characters in X.509 certificates. If an attacker is able to get a carefully-crafted certificate signed by a trusted Certificate Authority, the attacker could use the certificate during a man-in-the-middle attack and potentially confuse cURL into accepting it by mistake. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-2417 to this issue j. Updated Service Console package gnutls Service Console package gnutil updated to version 1.4.1-3.el5_3.5 A flaw was discovered in the way GnuTLS handles NULL characters in certain fields of X.509 certificates. If an attacker is able to get a carefully-crafted certificate signed by a Certificate Authority trusted by an application using GnuTLS, the attacker could use the certificate during a man-in-the-middle attack and potentially confuse the application into accepting it by mistake. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-2730 to this issue

    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-1895 Julien Tinnes and Tavis Ormandy reported an issue in the Linux personality code. Local users can take advantage of a setuid binary that can either be made to dereference a NULL pointer or drop privileges and return control to the user. This allows a user to bypass mmap_min_addr restrictions which can be exploited to execute arbitrary code. - CVE-2009-2287 Matt T. Yourst discovered an issue in the kvm subsystem. Local users with permission to manipulate /dev/kvm can cause a denial of service (hang) by providing an invalid cr3 value to the KVM_SET_SREGS call. - CVE-2009-2406 CVE-2009-2407 Ramon de Carvalho Valle discovered two issues with the eCryptfs layered filesystem using the fsfuzzer utility. A local user with permissions to perform an eCryptfs mount may modify the contents of a eCryptfs file, overflowing the stack and potentially gaining elevated privileges.

    description Michael Tokarev discovered that the RTL8169 network driver did not correctly validate buffer sizes. A remote attacker on the local network could send specially crafted traffic that would crash the system or potentially grant elevated privileges. (CVE-2009-1389) Julien Tinnes and Tavis Ormandy discovered that when executing setuid processes the kernel did not clear certain personality flags. A local attacker could exploit this to map the NULL memory page, causing other vulnerabilities to become exploitable. Ubuntu 6.06 was not affected. (CVE-2009-1895) Matt T. Yourst discovered that KVM did not correctly validate the page table root. A local attacker could exploit this to crash the system, leading to a denial of service. Ubuntu 6.06 was not affected.

    description From Red Hat Security Advisory 2009:1548 : Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes : * a system with SELinux enforced was more permissive in allowing local users in the unconfined_t domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important) * a NULL pointer dereference flaw was found in the eCryptfs implementation in the Linux kernel. A local attacker could use this flaw to cause a local denial of service or escalate their privileges. (CVE-2009-2908, Important) * a flaw was found in the NFSv4 implementation. The kernel would do an unnecessary permission check after creating a file. This check would usually fail and leave the file with the permission bits set to random values. Note: This is a server-side only issue. (CVE-2009-3286, Important) * a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important) * a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU space exhaustion and a system crash. An attacker on the local network could abuse this flaw by using jumbo frames for large amounts of network traffic. (CVE-2009-3613, Important) * missing initialization flaws were found in the Linux kernel. Padding data in several core network structures was not initialized properly before being sent to user-space. These flaws could lead to information leaks. (CVE-2009-3228, Moderate) Bug fixes : * with network bonding in the 'balance-tlb' or 'balance-alb' mode, the primary setting for the primary slave device was lost when said device was brought down. Bringing the slave back up did not restore the primary setting. (BZ#517971) * some faulty serial device hardware caused systems running the kernel-xen kernel to take a very long time to boot. (BZ#524153) * a caching bug in nfs_readdir() may have caused NFS clients to see duplicate files or not see all files in a directory. (BZ#526960) * the RHSA-2009:1243 update removed the mpt_msi_enable option, preventing certain scripts from running. This update adds the option back. (BZ#526963) * an iptables rule with the recent module and a hit count value greater than the ip_pkt_list_tot parameter (the default is 20), did not have any effect over packets, as the hit count could not be reached. (BZ#527434) * a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#527436) * a kernel panic occurred in certain conditions after reconfiguring a tape drive's block size. (BZ#528133) * when using the Linux Virtual Server (LVS) in a master and backup configuration, and propagating active connections on the master to the backup, the connection timeout value on the backup was hard-coded to 180 seconds, meaning connection information on the backup was soon lost. This could prevent the successful failover of connections. The timeout value can now be set via 'ipvsadm --set'. (BZ#528645) * a bug in nfs4_do_open_expired() could have caused the reclaimer thread on an NFSv4 client to enter an infinite loop. (BZ#529162) * MSI interrupts may not have been delivered for r8169 based network cards that have MSI interrupts enabled. This bug only affected certain systems. (BZ#529366) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes : * the possibility of a timeout value overflow was found in the Linux kernel high-resolution timers functionality, hrtimers. This could allow a local, unprivileged user to execute arbitrary code, or cause a denial of service (kernel panic). (CVE-2007-5966, Important) * a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check.

  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2009-1548.NASL
    description Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes : * a system with SELinux enforced was more permissive in allowing local users in the unconfined_t domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important) * a NULL pointer dereference flaw was found in the eCryptfs implementation in the Linux kernel. A local attacker could use this flaw to cause a local denial of service or escalate their privileges. (CVE-2009-2908, Important) * a flaw was found in the NFSv4 implementation. The kernel would do an unnecessary permission check after creating a file. This check would usually fail and leave the file with the permission bits set to random values. Note: This is a server-side only issue. (CVE-2009-3286, Important) * a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important) * a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU space exhaustion and a system crash. An attacker on the local network could abuse this flaw by using jumbo frames for large amounts of network traffic. (CVE-2009-3613, Important) * missing initialization flaws were found in the Linux kernel. Padding data in several core network structures was not initialized properly before being sent to user-space. These flaws could lead to information leaks. (CVE-2009-3228, Moderate) Bug fixes : * with network bonding in the 'balance-tlb' or 'balance-alb' mode, the primary setting for the primary slave device was lost when said device was brought down. Bringing the slave back up did not restore the primary setting. (BZ#517971) * some faulty serial device hardware caused systems running the kernel-xen kernel to take a very long time to boot. (BZ#524153) * a caching bug in nfs_readdir() may have caused NFS clients to see duplicate files or not see all files in a directory. (BZ#526960) * the RHSA-2009:1243 update removed the mpt_msi_enable option, preventing certain scripts from running. This update adds the option back. (BZ#526963) * an iptables rule with the recent module and a hit count value greater than the ip_pkt_list_tot parameter (the default is 20), did not have any effect over packets, as the hit count could not be reached. (BZ#527434) * a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#527436) * a kernel panic occurred in certain conditions after reconfiguring a tape drive's block size. (BZ#528133) * when using the Linux Virtual Server (LVS) in a master and backup configuration, and propagating active connections on the master to the backup, the connection timeout value on the backup was hard-coded to 180 seconds, meaning connection information on the backup was soon lost. This could prevent the successful failover of connections. The timeout value can now be set via 'ipvsadm --set'. (BZ#528645) * a bug in nfs4_do_open_expired() could have caused the reclaimer thread on an NFSv4 client to enter an infinite loop. (BZ#529162) * MSI interrupts may not have been delivered for r8169 based network cards that have MSI interrupts enabled. This bug only affected certain systems. (BZ#529366) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

  • NASL family Mandriva Local Security Checks
    NASL id MANDRIVA_MDVSA-2009-289.NASL
    description Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel : The personality subsystem in the Linux kernel before 2.6.31-rc3 has a PER_CLEAR_ON_SETID setting that does not clear the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags when executing a setuid or setgid program, which makes it easier for local users to leverage the details of memory usage to (1) conduct NULL pointer dereference attacks, (2) bypass the mmap_min_addr protection mechanism, or (3) defeat address space layout randomization (ASLR). (CVE-2009-1895) Stack-based buffer overflow in the parse_tag_11_packet function in fs/ecryptfs/keystore.c in the eCryptfs subsystem in the Linux kernel before 2.6.30.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving a crafted eCryptfs file, related to not ensuring that the key signature length in a Tag 11 packet is compatible with the key signature buffer size. (CVE-2009-2406) Heap-based buffer overflow in the parse_tag_3_packet function in fs/ecryptfs/keystore.c in the eCryptfs subsystem in the Linux kernel before 2.6.30.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving a crafted eCryptfs file, related to a large encrypted key size in a Tag 3 packet. (CVE-2009-2407) The d_delete function in fs/ecryptfs/inode.c in eCryptfs in the Linux kernel 2.6.31 allows local users to cause a denial of service (kernel OOPS) and possibly execute arbitrary code via unspecified vectors that cause a negative dentry and trigger a NULL pointer dereference, as demonstrated via a Mutt temporary directory in an eCryptfs mount. (CVE-2009-2908) The kvm_emulate_hypercall function in arch/x86/kvm/x86.c in KVM in the Linux kernel 2.6.25-rc1, and other versions before 2.6.31, when running on x86 systems, does not prevent access to MMU hypercalls from ring 0, which allows local guest OS users to cause a denial of service (guest kernel crash) and read or write guest kernel memory via unspecified random addresses. (CVE-2009-3290) Additionaly, it includes the fixes from the stable kernel version 2.6.27.37. It also fixes also fixes IBM x3650 M2 hanging when using both network interfaces and Wake on Lan problems on r8169. For details, check the package changelog.

This could,potentially, lead to a denial of service issue. (CVE-2008-5029, Important) - the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important) - the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important) - a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important) - the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2009-1895, Important) - it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important) - missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak. (CVE-2009-3002, Important) - a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important) Bug fixes : - this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer dereference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#512642) - a bridge reference count problem in IPv6 has been fixed. (BZ#457010) - enforce null-termination of user-supplied arguments to setsockopt(). (BZ#505514) - the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#511185) - a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#520300) The system must be rebooted for this update to take effect.

If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important) * Solar Designer reported a missing capability check in the z90crypt driver in the Linux kernel. This missing check could allow a local user with an effective user ID (euid) of 0 to bypass intended capability restrictions. (CVE-2009-1883, Moderate) * a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak. (CVE-2009-2847, Moderate) This update also fixes the following bugs : * the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#517964) * the Emulex LPFC driver has been updated to version 8.0.16.47, which fixes a memory leak that caused memory allocation failures and system hangs. (BZ#513192) * an error in the MPT Fusion driver makefile caused CSMI ioctls to not work with Serial Attached SCSI devices. (BZ#516184) * this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer deference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#517904) * time-outs resulted in I/O errors being logged to '/var/log/messages' when running 'mt erase' on tape drives using certain LSI MegaRAID SAS adapters, preventing the command from completing. The megaraid_sas driver's timeout value is now set to the OS layer value. (BZ#517965) * a locking issue caused the qla2xxx ioctl module to hang after encountering errors. This locking issue has been corrected. This ioctl module is used by the QLogic SAN management tools, such as SANsurfer and scli. (BZ#519428) * when a RAID 1 array that uses the mptscsi driver and the LSI 1030 controller became degraded, the whole array was detected as being offline, which could cause kernel panics at boot or data loss. (BZ#517295) * on 32-bit architectures, if a file was held open and frequently written for more than 25 days, it was possible that the kernel would stop flushing those writes to storage. (BZ#515255) * a memory allocation bug in ib_mthca prevented the driver from loading if it was loaded with large values for the 'num_mpt=' and 'num_mtt=' options. (BZ#518707) * with this update, get_random_int() is more random and no longer uses a common seed value, reducing the possibility of predicting the values returned. (BZ#519692) * a bug in __ptrace_unlink() caused it to create deadlocked and unkillable processes. (BZ#519446) * previously, multiple threads using the fcntl() F_SETLK command to synchronize file access caused a deadlock in posix_locks_deadlock(). This could cause a system hang. (BZ#519429) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    title Scientific Linux Security Update : kernel for SL 5.x on i386/x86_64
  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2009-1193.NASL
    description Updated kernel packages that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes : * the possibility of a timeout value overflow was found in the Linux kernel high-resolution timers functionality, hrtimers. This could allow a local, unprivileged user to execute arbitrary code, or cause a denial of service (kernel panic). (CVE-2007-5966, Important) * a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important) * Michael Tokarev reported a flaw in the Realtek r8169 Ethernet driver in the Linux kernel. This driver allowed interfaces using this driver to receive frames larger than could be handled, which could lead to a remote denial of service or code execution. (CVE-2009-1389, Important) * the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2009-1895, Important) * Ramon de Carvalho Valle reported two flaws in the Linux kernel eCryptfs implementation. A local attacker with permissions to perform an eCryptfs mount could modify the metadata of the files in that eCrypfts mount to cause a buffer overflow, leading to a denial of service or privilege escalation. (CVE-2009-2406, CVE-2009-2407, Important) * Konstantin Khlebnikov discovered a race condition in the ptrace implementation in the Linux kernel. This race condition can occur when the process tracing and the process being traced participate in a core dump. A local, unprivileged user could use this flaw to trigger a deadlock, resulting in a partial denial of service. (CVE-2009-1388, Moderate) Bug fixes (see References below for a link to more detailed notes) : * possible dom0 crash when a Xen para-virtualized guest was installed while another para-virtualized guest was rebooting. (BZ#497812) * no directory removal audit record if the directory and its subtree were recursively watched by an audit rule. (BZ#507561) * running 'echo 1 > /proc/sys/vm/drop_caches' under high memory load could cause a kernel panic. (BZ#503692) * on 32-bit systems, core dumps for some multithreaded applications did not include all thread information. (BZ#505322) * a stack buffer used by get_event_name() was too small for nul terminator sprintf() writes. This could lead to an invalid pointer or kernel panic. (BZ#506906) * when using the aic94xx driver, systems with SATA drives may not boot due to a libsas bug. (BZ#506029) * Wacom Cintiq 21UX and Intuos stylus buttons were handled incorrectly when moved away from and back to these tablets. (BZ#508275) * CPU 'soft lockup' messages and possibe system hangs on systems with certain Broadcom network devices and running the Linux kernel from the kernel-xen package. (BZ#503689) * on 64-bit PowerPC, getitimer() failed for programs using the ITIMER_REAL timer that were also compiled for 64-bit systems. This caused such programs to abort.

    description Updated kernel packages that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2009-1895, Important) * it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important) * Solar Designer reported a missing capability check in the z90crypt driver in the Linux kernel. This missing check could allow a local user with an effective user ID (euid) of 0 to bypass intended capability restrictions. (CVE-2009-1883, Moderate) * a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak. (CVE-2009-2847, Moderate) This update also fixes the following bugs : * the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#517964) * the Emulex LPFC driver has been updated to version 8.0.16.47, which fixes a memory leak that caused memory allocation failures and system hangs. (BZ#513192) * an error in the MPT Fusion driver makefile caused CSMI ioctls to not work with Serial Attached SCSI devices. (BZ#516184) * this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer deference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#517904) * time-outs resulted in I/O errors being logged to '/var/log/messages' when running 'mt erase' on tape drives using certain LSI MegaRAID SAS adapters, preventing the command from completing. The megaraid_sas driver's timeout value is now set to the OS layer value. (BZ#517965) * a locking issue caused the qla2xxx ioctl module to hang after encountering errors. This locking issue has been corrected. This ioctl module is used by the QLogic SAN management tools, such as SANsurfer and scli. (BZ#519428) * when a RAID 1 array that uses the mptscsi driver and the LSI 1030 controller became degraded, the whole array was detected as being offline, which could cause kernel panics at boot or data loss. (BZ#517295) * on 32-bit architectures, if a file was held open and frequently written for more than 25 days, it was possible that the kernel would stop flushing those writes to storage. (BZ#515255) * a memory allocation bug in ib_mthca prevented the driver from loading if it was loaded with large values for the 'num_mpt=' and 'num_mtt=' options. (BZ#518707) * with this update, get_random_int() is more random and no longer uses a common seed value, reducing the possibility of predicting the values returned. (BZ#519692) * a bug in __ptrace_unlink() caused it to create deadlocked and unkillable processes. (BZ#519446) * previously, multiple threads using the fcntl() F_SETLK command to synchronize file access caused a deadlock in posix_locks_deadlock(). This could cause a system hang. (BZ#519429) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes : * when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a denial of service issue. (CVE-2008-5029, Important) * the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important) * the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important) * a flaw was found in the Intel PRO/1000 network driver in the Linux kernel.

(CVE-2009-2848, Important) * missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak. (CVE-2009-3002, Important) * a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open().

    description Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes : * a system with SELinux enforced was more permissive in allowing local users in the unconfined_t domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important) * a NULL pointer dereference flaw was found in the eCryptfs implementation in the Linux kernel. A local attacker could use this flaw to cause a local denial of service or escalate their privileges. (CVE-2009-2908, Important) * a flaw was found in the NFSv4 implementation. The kernel would do an unnecessary permission check after creating a file. This check would usually fail and leave the file with the permission bits set to random values. Note: This is a server-side only issue. (CVE-2009-3286, Important) * a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important) * a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU space exhaustion and a system crash. An attacker on the local network could abuse this flaw by using jumbo frames for large amounts of network traffic. (CVE-2009-3613, Important) * missing initialization flaws were found in the Linux kernel. Padding data in several core network structures was not initialized properly before being sent to user-space. These flaws could lead to information leaks. (CVE-2009-3228, Moderate) Bug fixes : * with network bonding in the 'balance-tlb' or 'balance-alb' mode, the primary setting for the primary slave device was lost when said device was brought down. Bringing the slave back up did not restore the primary setting. (BZ#517971) * some faulty serial device hardware caused systems running the kernel-xen kernel to take a very long time to boot. (BZ#524153) * a caching bug in nfs_readdir() may have caused NFS clients to see duplicate files or not see all files in a directory. (BZ#526960) * the RHSA-2009:1243 update removed the mpt_msi_enable option, preventing certain scripts from running. This update adds the option back. (BZ#526963) * an iptables rule with the recent module and a hit count value greater than the ip_pkt_list_tot parameter (the default is 20), did not have any effect over packets, as the hit count could not be reached. (BZ#527434) * a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#527436) * a kernel panic occurred in certain conditions after reconfiguring a tape drive's block size. (BZ#528133) * when using the Linux Virtual Server (LVS) in a master and backup configuration, and propagating active connections on the master to the backup, the connection timeout value on the backup was hard-coded to 180 seconds, meaning connection information on the backup was soon lost. This could prevent the successful failover of connections. The timeout value can now be set via 'ipvsadm --set'. (BZ#528645) * a bug in nfs4_do_open_expired() could have caused the reclaimer thread on an NFSv4 client to enter an infinite loop. (BZ#529162) * MSI interrupts may not have been delivered for r8169 based network cards that have MSI interrupts enabled. This bug only affected certain systems. (BZ#529366) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description This kernel update for openSUSE 11.0 fixes some bugs and several security problems. The following security issues are fixed: CVE-2009-2692: A missing NULL pointer check in the socket sendpage function can be used by local attackers to gain root privileges. CVE-2009-2406: A kernel stack overflow when mounting eCryptfs filesystems in parse_tag_11_packet() was fixed. Code execution might be possible of ecryptfs is in use. CVE-2009-2407: A kernel heap overflow when mounting eCryptfs filesystems in parse_tag_3_packet() was fixed. Code execution might be possible of ecryptfs is in use. The compiler option -fno-delete-null-pointer-checks was added to the kernel build, and the -fwrapv compiler option usage was fixed to be used everywhere. This works around the compiler removing checks too aggressively. CVE-2009-1389: A crash in the r8169 driver when receiving large packets was fixed. This is probably exploitable only in the local network. CVE-2009-1895: Personality flags on set*id were not cleared correctly, so ASLR and NULL page protection could be bypassed. CVE-2009-1046: A utf-8 console memory corruption that can be used for local privilege escalation was fixed. The NULL page protection using mmap_min_addr was enabled (was disabled before). No CVE yet: A sigaltstack kernel memory disclosure was fixed. CVE-2008-5033: A local denial of service (Oops) in video4linux tvaudio was fixed. CVE-2009-1385: A Integer underflow in the e1000_clean_rx_irq function in drivers/net/e1000/e1000_main.c in the e1000 driver the e1000e driver in the Linux kernel, and Intel Wired Ethernet (aka e1000) before 7.5.5 allows remote attackers to cause a denial of service (panic) via a crafted frame size.

This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * a flaw was found in the IPv6 Extension Header (EH) handling implementation in the Linux kernel. The skb->dst data structure was not properly validated in the ipv6_hop_jumbo() function. This could possibly lead to a remote denial of service. (CVE-2007-4567, Important) * the possibility of a timeout value overflow was found in the Linux kernel high-resolution timers functionality, hrtimers. This could allow a local, unprivileged user to execute arbitrary code, or cause a denial of service (kernel panic). (CVE-2007-5966, Important) * memory leaks were found on some error paths in the icmp_send() function in the Linux kernel. This could, potentially, cause the network connectivity to cease. (CVE-2009-0778, Important) * a deficiency was found in the Linux kernel system call auditing implementation on 64-bit systems. This could allow a local, unprivileged user to circumvent a system call audit configuration, if that configuration filtered based on the 'syscall' number or arguments. (CVE-2009-0834, Important) * a flaw was found in the Intel PRO/1000 Linux driver (e1000) in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important) * the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2009-1895, Important) * a flaw was found in each of the following Intel PRO/1000 Linux drivers in the Linux kernel: e1000 and e1000e. A remote attacker using packets larger than the MTU could bypass the existing fragment check, resulting in partial, invalid frames being passed to the network stack. These flaws could also possibly be used to trigger a remote denial of service. (CVE-2009-4536, CVE-2009-4538, Important) * a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. Receiving overly-long frames with a certain revision of the network cards supported by this driver could possibly result in a remote denial of service. (CVE-2009-4537, Important) Note: This update also fixes several bugs.

(CVE-2008-5300, Important) * the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important) * a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important) * the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2009-1895, Important) * it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important) * missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak. (CVE-2009-3002, Important) * a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important) Bug fixes : * this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer dereference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#512642) * a bridge reference count problem in IPv6 has been fixed. (BZ#457010) * enforce null-termination of user-supplied arguments to setsockopt(). (BZ#505514) * the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#511185) * a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#520300) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-1844.NASL
    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-1385 Neil Horman discovered a missing fix from the e1000 network driver. A remote user may cause a denial of service by way of a kernel panic triggered by specially crafted frame sizes. - CVE-2009-1389 Michael Tokarev discovered an issue in the r8169 network driver. Remote users on the same LAN may cause a denial of service by way of a kernel panic triggered by receiving a large size frame. - CVE-2009-1630 Frank Filz discovered that local users may be able to execute files without execute permission when accessed via an nfs4 mount. - CVE-2009-1633 Jeff Layton and Suresh Jayaraman fixed several buffer overflows in the CIFS filesystem which allow remote servers to cause memory corruption. - CVE-2009-1895 Julien Tinnes and Tavis Ormandy reported an issue in the Linux personality code. Local users can take advantage of a setuid binary that can either be made to dereference a NULL pointer or drop privileges and return control to the user. This allows a user to bypass mmap_min_addr restrictions which can be exploited to execute arbitrary code. - CVE-2009-1914 Mikulas Patocka discovered an issue in sparc64 kernels that allows local users to cause a denial of service (crash) by reading the /proc/iomem file. - CVE-2009-1961 Miklos Szeredi reported an issue in the ocfs2 filesystem. Local users can create a denial of service (filesystem deadlock) using a particular sequence of splice system calls. - CVE-2009-2406 CVE-2009-2407 Ramon de Carvalho Valle discovered two issues with the eCryptfs layered filesystem using the fsfuzzer utility. A local user with permissions to perform an eCryptfs mount may modify the contents of a eCryptfs file, overflowing the stack and potentially gaining elevated privileges.

    description From Red Hat Security Advisory 2009:1438 : Updated kernel packages that fix several security issues and several bugs are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2009-1895, Important) * it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important) * Solar Designer reported a missing capability check in the z90crypt driver in the Linux kernel. This missing check could allow a local user with an effective user ID (euid) of 0 to bypass intended capability restrictions. (CVE-2009-1883, Moderate) * a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak. (CVE-2009-2847, Moderate) This update also fixes the following bugs : * the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#517964) * the Emulex LPFC driver has been updated to version 8.0.16.47, which fixes a memory leak that caused memory allocation failures and system hangs. (BZ#513192) * an error in the MPT Fusion driver makefile caused CSMI ioctls to not work with Serial Attached SCSI devices. (BZ#516184) * this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer deference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#517904) * time-outs resulted in I/O errors being logged to '/var/log/messages' when running 'mt erase' on tape drives using certain LSI MegaRAID SAS adapters, preventing the command from completing. The megaraid_sas driver's timeout value is now set to the OS layer value. (BZ#517965) * a locking issue caused the qla2xxx ioctl module to hang after encountering errors. This locking issue has been corrected. This ioctl module is used by the QLogic SAN management tools, such as SANsurfer and scli. (BZ#519428) * when a RAID 1 array that uses the mptscsi driver and the LSI 1030 controller became degraded, the whole array was detected as being offline, which could cause kernel panics at boot or data loss. (BZ#517295) * on 32-bit architectures, if a file was held open and frequently written for more than 25 days, it was possible that the kernel would stop flushing those writes to storage. (BZ#515255) * a memory allocation bug in ib_mthca prevented the driver from loading if it was loaded with large values for the 'num_mpt=' and 'num_mtt=' options. (BZ#518707) * with this update, get_random_int() is more random and no longer uses a common seed value, reducing the possibility of predicting the values returned. (BZ#519692) * a bug in __ptrace_unlink() caused it to create deadlocked and unkillable processes. (BZ#519446) * previously, multiple threads using the fcntl() F_SETLK command to synchronize file access caused a deadlock in posix_locks_deadlock(). This could cause a system hang. (BZ#519429) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
