CWE CWE-264
CAPEC
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

    description IPv6 fragment identification value generation could allow a remote attacker to disrupt a target system's networking, preventing legitimate users from accessing its services. (CVE-2011-2699 , Important) A signedness issue was found in the Linux kernel's CIFS (Common Internet File System) implementation. A malicious CIFS server could send a specially crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted. (CVE-2011-3191 , Important) A flaw was found in the way the Linux kernel handled fragmented IPv6 UDP datagrams over the bridge with UDP Fragmentation Offload (UFO) functionality on. A remote attacker could use this flaw to cause a denial of service. (CVE-2011-4326 , Important) The way IPv4 and IPv6 protocol sequence numbers and fragment IDs were generated could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence numbers and fragment IDs are now more random. (CVE-2011-3188 , Moderate) A buffer overflow flaw was found in the Linux kernel's FUSE (Filesystem in Userspace) implementation. A local user in the fuse group who has access to mount a FUSE file system could use this flaw to cause a denial of service. (CVE-2011-3353 , Moderate) A flaw was found in the b43 driver in the Linux kernel. If a system had an active wireless interface that uses the b43 driver, an attacker able to send a specially crafted frame to that interface could cause a denial of service. (CVE-2011-3359 , Moderate) A flaw was found in the way CIFS shares with DFS referrals at their root were handled. An attacker on the local network who is able to deploy a malicious CIFS server could create a CIFS network share that, when mounted, would cause the client system to crash. (CVE-2011-3363 , Moderate) A flaw was found in the way the Linux kernel handled VLAN 0 frames with the priority tag set. When using certain network drivers, an attacker on the local network could use this flaw to cause a denial of service. (CVE-2011-3593 , Moderate) A flaw in the way memory containing security-related data was handled in tpm_read() could allow a local, unprivileged user to read the results of a previously run TPM command. (CVE-2011-1162 , Low) A heap overflow flaw was found in the Linux kernel's EFI GUID Partition Table (GPT) implementation. A local attacker could use this flaw to cause a denial of service by mounting a disk that contains specially crafted partition tables. (CVE-2011-1577 , Low) The I/O statistics from the taskstats subsystem could be read without any restrictions. A local, unprivileged user could use this flaw to gather confidential information, such as the length of a password used in a process. (CVE-2011-2494 , Low) It was found that the perf tool, a part of the Linux kernel's Performance Events implementation, could load its configuration file from the current working directory. If a local user with access to the perf tool were tricked into running perf in a directory that contains a specially crafted configuration file, it could cause perf to overwrite arbitrary files and directories accessible to that user.

    description Updated kernel packages that fix multiple security issues, address several hundred bugs and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 6. This is the second regular update. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * The proc file system could allow a local, unprivileged user to obtain sensitive information or possibly cause integrity issues. (CVE-2011-1020, Moderate) * Non-member VLAN (virtual LAN) packet handling for interfaces in promiscuous mode and also using the be2net driver could allow an attacker on the local network to cause a denial of service. (CVE-2011-3347, Moderate) * A flaw was found in the Linux kernel in the way splitting two extents in ext4_ext_convert_to_initialized() worked. A local, unprivileged user with access to mount and unmount ext4 file systems could use this flaw to cause a denial of service. (CVE-2011-3638, Moderate) * A NULL pointer dereference flaw was found in the way the Linux kernel's key management facility handled user-defined key types. A local, unprivileged user could use the keyctl utility to cause a denial of service. (CVE-2011-4110, Moderate) Red Hat would like to thank Kees Cook for reporting CVE-2011-1020; Somnath Kotur for reporting CVE-2011-3347; and Zheng Liu for reporting CVE-2011-3638. This update also fixes several hundred bugs and adds enhancements. Refer to the Red Hat Enterprise Linux 6.2 Release Notes for information on the most significant of these changes, and the Technical Notes for further information, both linked to in the References. All Red Hat Enterprise Linux 6 users are advised to install these updated packages, which correct these issues, and fix the bugs and add the enhancements noted in the Red Hat Enterprise Linux 6.2 Release Notes and Technical Notes. The system must be rebooted for this update to take effect.

    NASL id SUSE_KERNEL-8325.NASL
    description This Linux kernel update fixes various security issues and bugs in the SUSE Linux Enterprise 10 SP4 kernel. The following security issues have been fixed : - kernel/taskstats.c in the Linux kernel allowed local users to obtain sensitive I/O statistics by sending taskstats commands to a netlink socket, as demonstrated by discovering the length of another users password (a side channel attack). (CVE-2011-2494) - net/ipv6/netfilter/nf_conntrack_reasm.c in the Linux kernel, when the nf_conntrack_ipv6 module is enabled, allowed remote attackers to cause a denial of service (NULL pointer dereference and system crash) via certain types of fragmented IPv6 packets. (CVE-2012-2744) - Use-after-free vulnerability in the xacct_add_tsk function in kernel/tsacct.c in the Linux kernel allowed local users to obtain potentially sensitive information from kernel memory or cause a denial of service (system crash) via a taskstats TASKSTATS_CMD_ATTR_PID command. (CVE-2012-3510) - The user_update function in security/keys/user_defined.c in the Linux kernel 2.6 allowed local users to cause a denial of service (NULL pointer dereference and kernel oops) via vectors related to a user-defined key and updating a negative key into a fully instantiated key. (CVE-2011-4110) - The ib_uverbs_poll_cq function in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel did not initialize a certain response buffer, which allowed local users to obtain potentially sensitive information from kernel memory via vectors that cause this buffer to be only partially filled, a different vulnerability than CVE-2010-4649. (CVE-2011-1044) - Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel allowed remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem. (CVE-2012-3400) - The sock_alloc_send_pskb function in net/core/sock.c in the Linux kernel did not properly validate a certain length value, which allowed local users to cause a denial of service (heap-based buffer overflow and system crash) or possibly gain privileges by leveraging access to a TUN/TAP device.

    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-2011-2183 Andrea Righi reported an issue in KSM, a memory-saving de-duplication feature. By exploiting a race with exiting tasks, local users can cause a kernel oops, resulting in a denial of service. - CVE-2011-2213 Dan Rosenberg discovered an issue in the INET socket monitoring interface. Local users could cause a denial of service by injecting code and causing the kernel to execute an infinite loop. - CVE-2011-2898 Eric Dumazet reported an information leak in the raw packet socket implementation. - CVE-2011-3353 Han-Wen Nienhuys reported a local denial of service issue in the FUSE (Filesystem in Userspace) support in the Linux kernel. Local users could cause a buffer overflow, leading to a kernel oops and resulting in a denial of service. - CVE-2011-4077 Carlos Maiolino reported an issue in the XFS filesystem. A local user with the ability to mount a filesystem could corrupt memory resulting in a denial of service or possibly gain elevated privileges. - CVE-2011-4110 David Howells reported an issue in the kernel's access key retention system which allow local users to cause a kernel oops leading to a denial of service. - CVE-2011-4127 Paolo Bonzini of Red Hat reported an issue in the ioctl passthrough support for SCSI devices. Users with permission to access restricted portions of a device (e.g. a partition or a logical volume) can obtain access to the entire device by way of the SG_IO ioctl. This could be exploited by a local user or privileged VM guest to achieve a privilege escalation. - CVE-2011-4611 Maynard Johnson reported an issue with the perf support on POWER7 systems that allows local users to cause a denial of service. - CVE-2011-4622 Jan Kiszka reported an issue in the KVM PIT timer support. Local users with the permission to use KVM can cause a denial of service by starting a PIT timer without first setting up the irqchip. - CVE-2011-4914 Ben Hutchings reported various bounds checking issues within the ROSE protocol support in the kernel. Remote users could possibly use this to gain access to sensitive memory or cause a denial of service.

    description Updated kernel-rt packages that fix multiple security issues and various bugs are now available for Red Hat Enterprise MRG 2.1. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. These packages contain the Linux kernel. Security fixes : * SG_IO ioctl SCSI requests on partitions or LVM volumes could be passed to the underlying block device, allowing a privileged user to bypass restrictions and gain read and write access (and be able to issue other SCSI commands) to the entire block device. (CVE-2011-4127, Important) * A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. (CVE-2012-0044, Important) * A local, unprivileged user could use a flaw in the Performance Events implementation to cause a denial of service. (CVE-2011-2918, Moderate) * A local, unprivileged user could use flaws in the XFS file system implementation to cause a denial of service or escalate their privileges by mounting a specially crafted disk. (CVE-2011-4077, CVE-2012-0038, Moderate) * A local, unprivileged user could use a flaw in the Out of Memory (OOM) killer to monopolize memory, have their process skipped by the OOM killer, or cause other tasks to be terminated. (CVE-2011-4097, Moderate) * A local, unprivileged user could use a flaw in the key management facility to cause a denial of service. (CVE-2011-4110, Moderate) * A malicious Network File System version 4 (NFSv4) server could return a crafted reply to a GETACL request, causing a denial of service on the client. (CVE-2011-4131, Moderate) * A local attacker could use a flaw in the Journaling Block Device (JBD) to crash the system by mounting a specially crafted ext3 or ext4 disk. (CVE-2011-4132, Moderate) * A flaw in igmp_heard_query() could allow an attacker, who is able to send certain IGMP (Internet Group Management Protocol) packets to a target system, to cause a denial of service. (CVE-2012-0207, Moderate) * If lock contention during signal sending occurred when in a software interrupt handler that is using the per-CPU debug stack, the task could be scheduled out on the realtime kernel, possibly leading to debug stack corruption. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-0810, Moderate) Red Hat would like to thank Chen Haogang for reporting CVE-2012-0044; Wang Xi for reporting CVE-2012-0038; Shubham Goyal for reporting CVE-2011-4097; Andy Adamson for reporting CVE-2011-4131; and Simon McVittie for reporting CVE-2012-0207. Bug fixes : * When a sleeping task, waiting on a futex (fast userspace mutex), tried to get the spin_lock(hb->lock) RT-mutex, if the owner of the futex released the lock, the sleeping task was put on a futex proxy lock. Consequently, the sleeping task was blocked on two locks and eventually terminated in the BUG_ON() function. With this update, the WAKEUP_INPROGRESS pseudo-lock has been added to be used as a proxy lock. This pseudo-lock tells the sleeping task that it is being woken up so that the task no longer tries to get the second lock. Now, the futex code works as expected and sleeping tasks no longer crash in the described scenario. (BZ#784733) * When the CONFIG_CRYPTO_FIPS configuration option was disabled, some services such as sshd and ipsec, while working properly, returned warning messages regarding this missing option during start up. With this update, CONFIG_CRYPTO_FIPS has been enabled and no warning messages are now returned in the described scenario. (BZ#786145) * Previously, when a read operation on a loop device failed, the data successfully read from the device was not cleared and could eventually leak. This bug has been fixed and all data are now properly cleared in the described scenario. (BZ#761420) * Due to an assembler-sourced object, the perf utility (from the perf-rt package) for AMD64 and Intel 64 architectures contained an executable stack. This update adds the '.note.GNU-stack' section definition to the bench/mem-memcpy-x86-64-asm.S component of perf, with all flags disabled, and perf no longer contains an executable stack, thus fixing this bug.

    description From Red Hat Security Advisory 2011:1479 : Updated kernel packages that fix multiple security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * Using PCI passthrough without interrupt remapping support allowed Xen hypervisor guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. Refer to Red Hat Bugzilla bug 715555 for details. (CVE-2011-1898, Important) * A flaw was found in the way CIFS (Common Internet File System) shares with DFS referrals at their root were handled. An attacker on the local network who is able to deploy a malicious CIFS server could create a CIFS network share that, when mounted, would cause the client system to crash. (CVE-2011-3363, Moderate) * A NULL pointer dereference flaw was found in the way the Linux kernel's key management facility handled user-defined key types. A local, unprivileged user could use the keyctl utility to cause a denial of service. (CVE-2011-4110, Moderate) * A flaw in the way memory containing security-related data was handled in tpm_read() could allow a local, unprivileged user to read the results of a previously run TPM command. (CVE-2011-1162, Low) * A NULL pointer dereference flaw was found in the Linux kernel's HFS file system implementation. A local attacker could use this flaw to cause a denial of service by mounting a disk that contains a specially crafted HFS file system with a corrupted MDB extent record. (CVE-2011-2203, Low) * The I/O statistics from the taskstats subsystem could be read without any restrictions. A local, unprivileged user could use this flaw to gather confidential information, such as the length of a password used in a process. (CVE-2011-2494, Low) Red Hat would like to thank Yogesh Sharma for reporting CVE-2011-3363; Peter Huewe for reporting CVE-2011-1162; Clement Lecigne for reporting CVE-2011-2203; and Vasiliy Kulikov of Openwall for reporting CVE-2011-2494. This update also fixes several bugs and adds one enhancement. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs and add the enhancement noted in the Technical Notes. The system must be rebooted for this update to take effect.

    NASL id SUSE_KERNEL-8324.NASL
    description This Linux kernel update fixes various security issues and bugs in the SUSE Linux Enterprise 10 SP4 kernel. The following security issues have been fixed : - kernel/taskstats.c in the Linux kernel allowed local users to obtain sensitive I/O statistics by sending taskstats commands to a netlink socket, as demonstrated by discovering the length of another users password (a side channel attack). (CVE-2011-2494) - net/ipv6/netfilter/nf_conntrack_reasm.c in the Linux kernel, when the nf_conntrack_ipv6 module is enabled, allowed remote attackers to cause a denial of service (NULL pointer dereference and system crash) via certain types of fragmented IPv6 packets. (CVE-2012-2744) - Use-after-free vulnerability in the xacct_add_tsk function in kernel/tsacct.c in the Linux kernel allowed local users to obtain potentially sensitive information from kernel memory or cause a denial of service (system crash) via a taskstats TASKSTATS_CMD_ATTR_PID command. (CVE-2012-3510) - The user_update function in security/keys/user_defined.c in the Linux kernel 2.6 allowed local users to cause a denial of service (NULL pointer dereference and kernel oops) via vectors related to a user-defined key and updating a negative key into a fully instantiated key. (CVE-2011-4110) - The ib_uverbs_poll_cq function in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel did not initialize a certain response buffer, which allowed local users to obtain potentially sensitive information from kernel memory via vectors that cause this buffer to be only partially filled, a different vulnerability than CVE-2010-4649. (CVE-2011-1044) - Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel allowed remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem. (CVE-2012-3400) - The sock_alloc_send_pskb function in net/core/sock.c in the Linux kernel did not properly validate a certain length value, which allowed local users to cause a denial of service (heap-based buffer overflow and system crash) or possibly gain privileges by leveraging access to a TUN/TAP device. (CVE-2012-2136) - A small denial of service leak in dropping syn+fin messages was fixed. (CVE-2012-2663) The following non-security issues have been fixed : Packaging : - kbuild: Fix gcc -x syntax (bnc#773831). NFS : - knfsd: An assortment of little fixes to the sunrpc cache code. (bnc#767766) - knfsd: Unexport cache_fresh and fix a small race. (bnc#767766) - knfsd: nfsd: do not drop silently on upcall deferral.

(bnc#767766) - sunrpc/cache: recheck cache validity after cache_defer_req. (bnc#767766) - sunrpc/cache: use list_del_init for the list_head entries in cache_deferred_req. (bnc#767766) - sunrpc/cache: avoid variable over-loading in cache_defer_req. (bnc#767766) - sunrpc/cache: allow thread to block while waiting for cache update. (bnc#767766) - sunrpc/cache: Fix race in sunrpc/cache introduced by patch to allow thread to block while waiting for cache update. (bnc#767766) - sunrpc/cache: Another fix for race problem with sunrpc cache deferal. (bnc#767766) - knfsd: nfsd: make all exp_finding functions return -errnos on err. (bnc#767766) - Fix kabi breakage in previous nfsd patch series. (bnc#767766) - nfsd: Work around incorrect return type for wait_for_completion_interruptible_timeout. (bnc#767766) - nfs: Fix a potential file corruption issue when writing. (bnc#773272) - nfs: Allow sync writes to be multiple pages. (bnc#763526) - nfs: fix reference counting for NFSv4 callback thread. (bnc#767504) - nfs: flush signals before taking down callback thread. (bnc#767504) - nfsv4: Ensure nfs_callback_down() calls svc_destroy() (bnc#767504). SCSI : - SCSI/ch: Check NULL for kmalloc() return.

    NASL id SL_20111206_SCIENTIFIC_LINUX_6_KERNEL_ON_SL6_X.NASL
    description The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : - The proc file system could allow a local, unprivileged user to obtain sensitive information or possibly cause integrity issues. (CVE-2011-1020, Moderate) - Non-member VLAN (virtual LAN) packet handling for interfaces in promiscuous mode and also using the be2net driver could allow an attacker on the local network to cause a denial of service. (CVE-2011-3347, Moderate) - A flaw was found in the Linux kernel in the way splitting two extents in ext4_ext_convert_to_initialized() worked. A local, unprivileged user with access to mount and unmount ext4 file systems could use this flaw to cause a denial of service. (CVE-2011-3638, Moderate) - A NULL pointer dereference flaw was found in the way the Linux kernel's key management facility handled user-defined key types. A local, unprivileged user could use the keyctl utility to cause a denial of service. (CVE-2011-4110, Moderate) This update also fixes several hundred bugs and adds enhancements.

    NASL id REDHAT-RHSA-2012-0010.NASL
    description Updated kernel-rt packages that fix several security issues and two bugs are now available for Red Hat Enterprise MRG 2.0. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * A malicious CIFS (Common Internet File System) server could send a specially crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted. (CVE-2011-3191, Important) * The way fragmented IPv6 UDP datagrams over the bridge with UDP Fragmentation Offload (UFO) functionality on were handled could allow a remote attacker to cause a denial of service. (CVE-2011-4326, Important) * GRO (Generic Receive Offload) fields could be left in an inconsistent state. An attacker on the local network could use this flaw to cause a denial of service. GRO is enabled by default in all network drivers that support it. (CVE-2011-2723, Moderate) * IPv4 and IPv6 protocol sequence number and fragment ID generation could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence numbers and fragment IDs are now more random. (CVE-2011-3188, Moderate) * A flaw in the FUSE (Filesystem in Userspace) implementation could allow a local user in the fuse group who has access to mount a FUSE file system to cause a denial of service. (CVE-2011-3353, Moderate) * A flaw in the b43 driver. If a system had an active wireless interface that uses the b43 driver, an attacker able to send a specially crafted frame to that interface could cause a denial of service. (CVE-2011-3359, Moderate) * A flaw in the way CIFS shares with DFS referrals at their root were handled could allow an attacker on the local network, who is able to deploy a malicious CIFS server, to create a CIFS network share that, when mounted, would cause the client system to crash. (CVE-2011-3363, Moderate) * A flaw in the m_stop() implementation could allow a local, unprivileged user to trigger a denial of service. (CVE-2011-3637, Moderate) * Flaws in ghash_update() and ghash_final() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-4081, Moderate) * A flaw in the key management facility could allow a local, unprivileged user to cause a denial of service via the keyctl utility. (CVE-2011-4110, Moderate) * A flaw in the Journaling Block Device (JBD) could allow a local attacker to crash the system by mounting a specially crafted ext3 or ext4 disk. (CVE-2011-4132, Moderate) * A flaw in the way memory containing security-related data was handled in tpm_read() could allow a local, unprivileged user to read the results of a previously run TPM command. (CVE-2011-1162, Low) * I/O statistics from the taskstats subsystem could be read without any restrictions, which could allow a local, unprivileged user to gather confidential information, such as the length of a password used in a process. (CVE-2011-2494, Low) * Flaws in tpacket_rcv() and packet_recvmsg() could allow a local, unprivileged user to leak information to user-space. (CVE-2011-2898, Low) Red Hat would like to thank Darren Lavender for reporting CVE-2011-3191; Brent Meshier for reporting CVE-2011-2723; Dan Kaminsky for reporting CVE-2011-3188; Yogesh Sharma for reporting CVE-2011-3363; Nick Bowler for reporting CVE-2011-4081; Peter Huewe for reporting CVE-2011-1162; and Vasiliy Kulikov of Openwall for reporting CVE-2011-2494. This update also fixes the following bugs : * Previously, a mismatch in the build-id of the kernel-rt and the one in the related debuginfo package caused failures in SystemTap and perf. (BZ#768413) * IBM x3650m3 systems were not able to boot the MRG Realtime kernel because they require a pmcraid driver that was not available. The pmcraid driver is included in this update. (BZ#753992) Users should upgrade to these updated packages, which correct these issues. The system must be rebooted for this update to take effect.

    NASL id CENTOS_RHSA-2011-1479.NASL
    description Updated kernel packages that fix multiple security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * Using PCI passthrough without interrupt remapping support allowed Xen hypervisor guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. Refer to Red Hat Bugzilla bug 715555 for details. (CVE-2011-1898, Important) * A flaw was found in the way CIFS (Common Internet File System) shares with DFS referrals at their root were handled. An attacker on the local network who is able to deploy a malicious CIFS server could create a CIFS network share that, when mounted, would cause the client system to crash. (CVE-2011-3363, Moderate) * A NULL pointer dereference flaw was found in the way the Linux kernel's key management facility handled user-defined key types. A local, unprivileged user could use the keyctl utility to cause a denial of service. (CVE-2011-4110, Moderate) * A flaw in the way memory containing security-related data was handled in tpm_read() could allow a local, unprivileged user to read the results of a previously run TPM command. (CVE-2011-1162, Low) * A NULL pointer dereference flaw was found in the Linux kernel's HFS file system implementation. A local attacker could use this flaw to cause a denial of service by mounting a disk that contains a specially crafted HFS file system with a corrupted MDB extent record. (CVE-2011-2203, Low) * The I/O statistics from the taskstats subsystem could be read without any restrictions. A local, unprivileged user could use this flaw to gather confidential information, such as the length of a password used in a process. (CVE-2011-2494, Low) Red Hat would like to thank Yogesh Sharma for reporting CVE-2011-3363; Peter Huewe for reporting CVE-2011-1162; Clement Lecigne for reporting CVE-2011-2203; and Vasiliy Kulikov of Openwall for reporting CVE-2011-2494. This update also fixes several bugs and adds one enhancement. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs and add the enhancement noted in the Technical Notes. The system must be rebooted for this update to take effect.

    title Ubuntu 11.10 : linux vulnerability (USN-1336-1)
  • NASL family Scientific Linux Local Security Checks
    NASL id SL_20111129_KERNEL_ON_SL5_X.NASL
    description The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : - Using PCI passthrough without interrupt remapping support allowed Xen hypervisor guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting.(CVE-2011-1898, Important) - A flaw was found in the way CIFS (Common Internet File System) shares with DFS referrals at their root were handled. An attacker on the local network who is able to deploy a malicious CIFS server could create a CIFS network share that, when mounted, would cause the client system to crash. (CVE-2011-3363, Moderate) - A NULL pointer dereference flaw was found in the way the Linux kernel's key management facility handled user-defined key types. A local, unprivileged user could use the keyctl utility to cause a denial of service. (CVE-2011-4110, Moderate) - A flaw in the way memory containing security-related data was handled in tpm_read() could allow a local, unprivileged user to read the results of a previously run TPM command. (CVE-2011-1162, Low) - A NULL pointer dereference flaw was found in the Linux kernel's HFS file system implementation. A local attacker could use this flaw to cause a denial of service by mounting a disk that contains a specially crafted HFS file system with a corrupted MDB extent record. (CVE-2011-2203, Low) - The I/O statistics from the taskstats subsystem could be read without any restrictions. A local, unprivileged user could use this flaw to gather confidential information, such as the length of a password used in a process. (CVE-2011-2494, Low) This update also fixes several bugs and adds one enhancement. The system must be rebooted for this update to take effect.

    title Scientific Linux Security Update : kernel on SL5.x i386/x86_64
  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2011-1479.NASL
    description Updated kernel packages that fix multiple security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : * Using PCI passthrough without interrupt remapping support allowed Xen hypervisor guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. Refer to Red Hat Bugzilla bug 715555 for details. (CVE-2011-1898, Important) * A flaw was found in the way CIFS (Common Internet File System) shares with DFS referrals at their root were handled. An attacker on the local network who is able to deploy a malicious CIFS server could create a CIFS network share that, when mounted, would cause the client system to crash. (CVE-2011-3363, Moderate) * A NULL pointer dereference flaw was found in the way the Linux kernel's key management facility handled user-defined key types. A local, unprivileged user could use the keyctl utility to cause a denial of service. (CVE-2011-4110, Moderate) * A flaw in the way memory containing security-related data was handled in tpm_read() could allow a local, unprivileged user to read the results of a previously run TPM command. (CVE-2011-1162, Low) * A NULL pointer dereference flaw was found in the Linux kernel's HFS file system implementation. A local attacker could use this flaw to cause a denial of service by mounting a disk that contains a specially crafted HFS file system with a corrupted MDB extent record. (CVE-2011-2203, Low) * The I/O statistics from the taskstats subsystem could be read without any restrictions. A local, unprivileged user could use this flaw to gather confidential information, such as the length of a password used in a process. (CVE-2011-2494, Low) Red Hat would like to thank Yogesh Sharma for reporting CVE-2011-3363; Peter Huewe for reporting CVE-2011-1162; Clement Lecigne for reporting CVE-2011-2203; and Vasiliy Kulikov of Openwall for reporting CVE-2011-2494. This update also fixes several bugs and adds one enhancement. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs and add the enhancement noted in the Technical Notes. The system must be rebooted for this update to take effect.

  • NASL family Ubuntu Local Security Checks
    NASL id UBUNTU_USN-1325-1.NASL
    description Peter Huewe discovered an information leak in the handling of reading security-related TPM data. A local, unprivileged user could read the results of a previous TPM command. (CVE-2011-1162) Clement Lecigne discovered a bug in the HFS filesystem. A local attacker could exploit this to cause a kernel oops. (CVE-2011-2203) Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local user who can mount a FUSE file system could cause a denial of service. (CVE-2011-3353) A flaw was found in the b43 driver in the Linux kernel. An attacker could use this flaw to cause a denial of service if the system has an active wireless interface using the b43 driver. (CVE-2011-3359) A flaw was found in how the Linux kernel handles user-defined key types. An unprivileged local user could exploit this to crash the system. (CVE-2011-4110)
