ID CVE-2015-1593
Summary The stack randomization feature in the Linux kernel before 3.19.1 on 64-bit platforms uses incorrect data types for the results of bitwise left-shift operations, which makes it easier for attackers to bypass the ASLR protection mechanism by predicting the address of the top of the stack, related to the randomize_stack_top function in fs/binfmt_elf.c and the stack_maxrandom_size function in arch/x86/mm/mmap.c.

Exploitability:
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.

    NASL id SUSE_11_KERNEL-150306.NASL
    description The SUSE Linux Enterprise 11 SP3 kernel has been updated to receive various security and bugfixes. New features enabled : - The Ceph and rbd remote network block device drivers are now enabled and supported, to serve as client for SUSE Enterprise Storage 1.0. (FATE#318328) - Support to selected Bay Trail CPUs used in Point of Service Hardware was enabled. (FATE#317933) - Broadwell Legacy Audio, HDMI Audio and DisplayPort Audio support (Audio Driver: HD-A HDMI/DP Audio/HDA Analog/DSP) was enabled. (FATE#317347) The following security bugs have been fixed : - An integer overflow in the stack randomization on 64-bit systems lead to less effective stack ASLR on those systems. (bsc#917839). (CVE-2015-1593) - iptables rules could be bypassed if the specific network protocol module was not loaded, allowing e.g. SCTP to bypass the firewall if the sctp protocol was not enabled. (bsc#913059). (CVE-2014-8160) - A flaw was found in the way the Linux kernels splice() system call validated its parameters. On certain file systems, a local, unprivileged user could have used this flaw to write past the maximum file size, and thus crash the system. (bnc#915322). (CVE-2014-7822) - The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel did not ensure that Thread Local Storage (TLS) descriptors are loaded before proceeding with other steps, which made it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address. (bnc#911326). (CVE-2014-9419) - The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel did not validate a length value in the Extensions Reference (ER) System Use Field, which allowed local users to obtain sensitive information from kernel memory via a crafted iso9660 image. (bnc#912654). (CVE-2014-9584) - The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel did not properly choose memory locations for the vDSO area, which made it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD. (bnc#912705). (CVE-2014-9585) - The d_walk function in fs/dcache.c in the Linux kernel did not properly maintain the semantics of rename_lock, which allowed local users to cause a denial of service (deadlock and system hang) via a crafted application. (bnc#903640). (CVE-2014-8559) - The rock_continue function in fs/isofs/rock.c in the Linux kernel did not restrict the number of Rock Ridge continuation entries, which allowed local users to cause a denial of service (infinite loop, and system crash or hang) via a crafted iso9660 image (bsc#911325). (CVE-2014-9420) - The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel used an improper paravirt_enabled setting for KVM guest kernels, which made it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value (bnc#907818 909077 909078). (CVE-2014-8134) - The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel miscalculated the number of pages during the handling of a mapping failure, which allowed guest OS users to cause a denial of service (host OS page unpinning) or possibly have unspecified other impact by leveraging guest OS privileges. NOTE: this vulnerability exists because of an incorrect fix for CVE-2014-3601 (bsc#902675). (CVE-2014-8369) - arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel on Intel processors did not ensure that the value in the CR4 control register remains the same after a VM entry, which allowed host OS users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm access, as demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU. (bnc#902232). (CVE-2014-3690) - Race condition in arch/x86/kvm/x86.c in the Linux kernel allowed guest OS users to cause a denial of service (guest OS crash) via a crafted application that performs an MMIO transaction or a PIO transaction to trigger a guest userspace emulation error report, a similar issue to CVE-2010-5313. (bnc#905312). (CVE-2014-7842) - The Netlink implementation in the Linux kernel did not provide a mechanism for authorizing socket operations based on the opener of a socket, which allowed local users to bypass intended access restrictions and modify network configurations by using a Netlink socket for the (1) stdout or (2) stderr of a setuid program. (bnc#875051). (CVE-2014-0181) - The SCTP implementation in the Linux kernel allowed remote attackers to cause a denial of service (memory consumption) by triggering a large number of chunks in an associations output queue, as demonstrated by ASCONF probes, related to net/sctp/inqueue.c and net/sctp/sm_statefuns.c. (bnc#902351). (CVE-2014-3688) - The pivot_root implementation in fs/namespace.c in the Linux kernel did not properly interact with certain locations of a chroot directory, which allowed local users to cause a denial of service (mount-tree loop) via . (dot) values in both arguments to the pivot_root system call. (bnc#900644). (CVE-2014-7970) - The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the SCTP implementation in the Linux kernel allowed remote attackers to cause a denial of service (panic) via duplicate ASCONF chunks that trigger an incorrect uncork within the side-effect interpreter. (bnc#902349, bnc#904899).

  • NASL family Ubuntu Local Security Checks
    NASL id UBUNTU_USN-2562-1.NASL
    description Sun Baoliang discovered a use after free flaw in the Linux kernel's SCTP (Stream Control Transmission Protocol) subsystem during INIT collisions. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially escalate their privileges on the system. (CVE-2015-1421) Marcelo Leitner discovered a flaw in the Linux kernel's routing of packets to too many different dsts/too fast. A remote attacker can exploit this flaw to cause a denial of service (system crash). (CVE-2015-1465) An integer overflow was discovered in the stack randomization feature of the Linux kernel on 64 bit platforms. A local attacker could exploit this flaw to bypass the Address Space Layout Randomization (ASLR) protection mechanism. (CVE-2015-1593) An information leak was discovered in the Linux Kernel's handling of userspace configuration of the link layer control (LLC). A local user could exploit this flaw to read data from other sysctl settings. (CVE-2015-2041) An information leak was discovered in how the Linux kernel handles setting the Reliable Datagram Sockets (RDS) settings. A local user could exploit this flaw to read data from other sysctl settings. (CVE-2015-2042). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2015-1138.NASL
    description Updated kernel-rt packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise MRG 2.5. Red Hat Product Security 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. * It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important) * A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate) * A flaw was found in the way the Linux kernel's 32-bit emulation implementation handled forking or closing of a task with an 'int80' entry. A local user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-2830, Low) * It was found that the Linux kernel's ISO file system implementation did not correctly limit the traversal of Rock Ridge extension Continuation Entries (CE). An attacker with physical access to the system could use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service. (CVE-2014-9420, Low) * An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low) * A flaw was found in the way the nft_flush_table() function of the Linux kernel's netfilter tables implementation flushed rules that were referencing deleted chains. A local user who has the CAP_NET_ADMIN capability could use this flaw to crash the system. (CVE-2015-1573, Low) * An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four. (CVE-2015-1593, Low) Red Hat would like to thank Carl Henrik Lunde for reporting CVE-2014-9420 and CVE-2014-9584. The security impact of CVE-2015-1805 was discovered by Red Hat. This update provides a build of the kernel-rt package for Red Hat Enterprise MRG 2.5 that is layered on Red Hat Enterprise Linux 6, and fixes the following issues : * storvsc: get rid of overly verbose warning messages * storvsc: force discovery of LUNs that may have been removed * storvsc: in responce to a scan event, scan the hos * storvsc: NULL pointer dereference fix * futex: Mention key referencing differences between shared and private futexes * futex: Ensure get_futex_key_refs() always implies a barrier * kernel module: set nx before marking module MODULE_STATE_COMING * kernel module: Clean up ro/nx after early module load failures * btrfs: make xattr replace operations atomic * megaraid_sas: revert: Add release date and update driver version * radeon: fix kernel segfault in hwmonitor (BZ#1223077) Bug fix : * There is an XFS optimization that depended on a spinlock to disable preemption using the preempt_disable() function. When CONFIG_PREEMPT_RT is enabled on realtime kernels, spinlocks do not disable preemption while held, so the XFS critical section was not protected from preemption. Systems on the Realtime kernel-rt could lock up in this XFS optimization when a task that locked all the counters was then preempted by a realtime task, causing all callers of that lock to block indefinitely. This update disables the optimization when building a kernel with CONFIG_PREEMPT_RT_FULL enabled. (BZ#1217849) All kernel-rt users are advised to upgrade to these updated packages, which correct these issues and add these enhancements. The system must be rebooted for this update to take effect.

A local user who has the CAP_NET_ADMIN capability could use this flaw to crash the system. (CVE-2015-1573, Low) * An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four. (CVE-2015-1593, Low) Red Hat would like to thank Carl Henrik Lunde for reporting CVE-2014-9420 and CVE-2014-9584. The security impact of CVE-2015-1805 was discovered by Red Hat. The kernel-rt packages have been upgraded to version 3.10.0-229.7.2, which provides a number of bug fixes and enhancements over the previous version, including : * storvsc: get rid of overly verbose warning messages * storvsc: force discovery of LUNs that may have been removed * storvsc: in responce to a scan event, scan the hos * storvsc: NULL pointer dereference fix * futex: Mention key referencing differences between shared and private futexes * futex: Ensure get_futex_key_refs() always implies a barrier * kernel module: set nx before marking module MODULE_STATE_COMING * kernel module: Clean up ro/nx after early module load failures * btrfs: make xattr replace operations atomic * megaraid_sas: revert: Add release date and update driver version * radeon: fix kernel segfault in hwmonitor (BZ#1223955) Bug fix : * There is an XFS optimization that depended on a spinlock to disable preemption using the preempt_disable() function. When CONFIG_PREEMPT_RT is enabled on realtime kernels, spinlocks do not disable preemption while held, so the XFS critical section was not protected from preemption. Systems on the Realtime kernel-rt could lock up in this XFS optimization when a task that locked all the counters was then preempted by a realtime task, causing all callers of that lock to block indefinitely. This update disables the optimization when building a kernel with CONFIG_PREEMPT_RT_FULL enabled. (BZ#1223955) All kernel-rt users are advised to upgrade to these updated packages, which correct these issues and add these enhancements. The system must be rebooted for this update to take effect.

    description This update fixes the CVEs described below. A further issue, CVE-2014-9419, was considered, but appears to require extensive changes with a consequent high risk of regression. It is now unlikely to be fixed in squeeze-lts. CVE-2013-6885 It was discovered that under specific circumstances, a combination of write operations to write-combined memory and locked CPU instructions may cause a core hang on AMD 16h 00h through 0Fh processors. A local user can use this flaw to mount a denial of service (system hang) via a crafted application. For more information please refer to the AMD CPU erratum 793 in http://support.amd.com/TechDocs/51810_16h_00h-0Fh_Rev_Guide. pdf CVE-2014-7822 It was found that the splice() system call did not validate the given file offset and length. A local unprivileged user can use this flaw to cause filesystem corruption on ext4 filesystems, or possibly other effects. CVE-2014-8133 It was found that the espfix functionality can be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks for) and using it for stack. A local unprivileged user could potentially use this flaw to leak kernel stack addresses. CVE-2014-8134 It was found that the espfix functionality is wrongly disabled in a 32-bit KVM guest. A local unprivileged user could potentially use this flaw to leak kernel stack addresses. CVE-2014-8160 It was found that a netfilter (iptables or ip6tables) rule accepting packets to a specific SCTP, DCCP, GRE or UDPlite port/endpoint could result in incorrect connection tracking state. If only the generic connection tracking module (nf_conntrack) was loaded, and not the protocol-specific connection tracking module, this would allow access to any port/endpoint of the specified protocol. CVE-2014-9420 It was found that the ISO-9660 filesystem implementation (isofs) follows arbitrarily long chains, including loops, of Continuation Entries (CEs). This allows local users to mount a denial of service via a crafted disc image. CVE-2014-9584 It was found that the ISO-9660 filesystem implementation (isofs) does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted disc image. CVE-2014-9585 It was discovered that address randomisation for the vDSO in 64-bit processes is extremely biassed. A local unprivileged user could potentially use this flaw to bypass the ASLR protection mechanism. CVE-2015-1421 It was found that the SCTP implementation could free authentication state while it was still in use, resulting in heap corruption. This could allow remote users to cause a denial of service or privilege escalation. CVE-2015-1593 It was found that address randomisation for the initial stack in 64-bit processes was limited to 20 rather than 22 bits of entropy. A local unprivileged user could potentially use this flaw to bypass the ASLR protection mechanism. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, information leaks or privilege escalation. - CVE-2013-7421 / CVE-2014-9644 It was discovered that the Crypto API allowed unprivileged users to load arbitrary kernel modules. A local user can use this flaw to exploit vulnerabilities in modules that would not normally be loaded. - CVE-2014-7822 Akira Fujita found that the splice() system call did not validate the given file offset and length. A local unprivileged user can use this flaw to cause filesystem corruption on ext4 filesystems, or possibly other effects. - CVE-2014-8160 Florian Westphal discovered that a netfilter (iptables/ip6tables) rule accepting packets to a specific SCTP, DCCP, GRE or UDPlite port/endpoint could result in incorrect connection tracking state. If only the generic connection tracking module (nf_conntrack) was loaded, and not the protocol-specific connection tracking module, this would allow access to any port/endpoint of the specified protocol. - CVE-2014-8559 It was found that kernel functions that iterate over a directory tree can dead-lock or live-lock in case some of the directory entries were recently deleted or dropped from the cache. A local unprivileged user can use this flaw for denial of service. - CVE-2014-9585 Andy Lutomirski discovered that address randomisation for the vDSO in 64-bit processes is extremely biased. A local unprivileged user could potentially use this flaw to bypass the ASLR protection mechanism. - CVE-2014-9683 Dmitry Chernenkov discovered that eCryptfs writes past the end of the allocated buffer during encrypted filename decoding, resulting in local denial of service. - CVE-2015-0239 It was found that KVM did not correctly emulate the x86 SYSENTER instruction. An unprivileged user within a guest system that has not enabled SYSENTER, for example because the emulated CPU vendor is AMD, could potentially use this flaw to cause a denial of service or privilege escalation in that guest. - CVE-2015-1420 It was discovered that the open_by_handle_at() system call reads the handle size from user memory a second time after validating it. A local user with the CAP_DAC_READ_SEARCH capability could use this flaw for privilege escalation. - CVE-2015-1421 It was found that the SCTP implementation could free an authentication state while it was still in use, resulting in heap corruption.

    description The Linux kernel was updated to fix various bugs and security issues. Following security issues were fixed : - CVE-2014-8173: A NULL pointer dereference flaw was found in the way the Linux kernels madvise MADV_WILLNEED functionality handled page table locking. A local, unprivileged user could have used this flaw to crash the system. - CVE-2015-1593: A integer overflow reduced the effectiveness of the stack randomization on 64-bit systems. - CVE-2014-7822: A flaw was found in the way the Linux kernels splice() system call validated its parameters. On certain file systems, a local, unprivileged user could have used this flaw to write past the maximum file size, and thus crash the system. - CVE-2014-9419: The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel did not ensure that Thread Local Storage (TLS) descriptors are loaded before proceeding with other steps, which made it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address. - CVE-2014-8134: The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel used an improper paravirt_enabled setting for KVM guest kernels, which made it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value. - CVE-2014-8160: net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel generated incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allowed remote attackers to bypass intended access restrictions via packets with disallowed port numbers. - CVE-2014-9529: Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel allowed local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key. - CVE-2014-8559: The d_walk function in fs/dcache.c in the Linux kernel through did not properly maintain the semantics of rename_lock, which allowed local users to cause a denial of service (deadlock and system hang) via a crafted application. - CVE-2014-9420: The rock_continue function in fs/isofs/rock.c in the Linux kernel did not restrict the number of Rock Ridge continuation entries, which allowed local users to cause a denial of service (infinite loop, and system crash or hang) via a crafted iso9660 image. - CVE-2014-9584: The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel did not validate a length value in the Extensions Reference (ER) System Use Field, which allowed local users to obtain sensitive information from kernel memory via a crafted iso9660 image. - CVE-2014-9585: The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel did not properly choose memory locations for the vDSO area, which made it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD. Following bugs were fixed : - HID: usbhid: enable always-poll quirk for Elan Touchscreen 0103 (bnc#920901). - HID: usbhid: enable always-poll quirk for Elan Touchscreen 016f (bnc#920901). - HID: usbhid: enable always-poll quirk for Elan Touchscreen 009b (bnc#920901). - HID: usbhid: add another mouse that needs QUIRK_ALWAYS_POLL (bnc#920901). - HID: usbhid: fix PIXART optical mouse (bnc#920901). - HID: usbhid: enable always-poll quirk for Elan Touchscreen (bnc#920901). - HID: usbhid: add always-poll quirk (bnc#920901). - storvsc: ring buffer failures may result in I/O freeze (bnc#914175). - mm, vmscan: prevent kswapd livelock due to pfmemalloc-throttled process being killed (VM Functionality bnc#910150). - Input: evdev - fix EVIOCG{type} ioctl (bnc#904899). - mnt: Implicitly add MNT_NODEV on remount when it was implicitly added by mount (bsc#907988). - DocBook: Do not exceed argument list limit. - DocBook: Make mandocs parallel-safe. - mm: free compound page with correct order (bnc#913695). - udf: Check component length before reading it. - udf: Check path length when reading symlink. - udf: Verify symlink size before loading it. - udf: Verify i_size when loading inode. - xfs: remote attribute overwrite causes transaction overrun.

    title Scientific Linux Security Update : kernel on SL7.x x86_64
  • NASL family Oracle Linux Local Security Checks
    NASL id ORACLELINUX_ELSA-2015-1137.NASL
    description From Red Hat Security Advisory 2015:1137 : Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 7. Red Hat Product Security 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. * It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important) * A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate) * A flaw was found in the way the Linux kernel's 32-bit emulation implementation handled forking or closing of a task with an 'int80' entry. A local user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-2830, Low) * It was found that the Linux kernel's ISO file system implementation did not correctly limit the traversal of Rock Ridge extension Continuation Entries (CE). An attacker with physical access to the system could use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service. (CVE-2014-9420, Low) * An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low) * A flaw was found in the way the nft_flush_table() function of the Linux kernel's netfilter tables implementation flushed rules that were referencing deleted chains. A local user who has the CAP_NET_ADMIN capability could use this flaw to crash the system. (CVE-2015-1573, Low) * An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four. (CVE-2015-1593, Low) Red Hat would like to thank Carl Henrik Lunde for reporting CVE-2014-9420 and CVE-2014-9584. The security impact of the CVE-2015-1805 issue was discovered by Red Hat. This update also fixes several bugs. Documentation for these changes is available from the following Knowledgebase article: https://access.redhat.com/articles/1469163 All kernel users are advised to 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 The Linux kernel was updated to fix bugs and security issues : Following security issues were fixed: CVE-2015-2830: A flaw was found in the way the Linux kernels 32-bit emulation implementation handled forking or closing of a task with an int80 entry. A local user could have potentially used this flaw to escalate their privileges on the system. CVE-2015-2042: A kernel information leak in rds sysctl files was fixed. CVE-2014-9683: Off-by-one error in the ecryptfs_decode_from_filename function in fs/ecryptfs/crypto.c in the eCryptfs subsystem in the Linux kernel allowed local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted filename. CVE-2015-0275: A BUG_ON in ext4 was fixed which could be triggered by local users. CVE-2015-2666: A buffer overflow when loading microcode files into the kernel could be used by the administrator to execute code in the kernel, bypassing secure boot measures. - CVE-2015-1421: Use-after-free vulnerability in the sctp_assoc_update function in net/sctp/associola.c in the Linux kernel allowed remote attackers to cause a denial of service (slab corruption and panic) or possibly have unspecified other impact by triggering an INIT collision that leads to improper handling of shared-key data. - CVE-2015-2150: XSA-120: Guests were permitted to modify all bits of the PCI command register of passed through cards, which could lead to Host system crashes. - CVE-2015-0777: The XEN usb backend could leak information to the guest system due to copying uninitialized memory. - CVE-2015-1593: A integer overflow reduced the effectiveness of the stack randomization on 64-bit systems. - CVE-2014-9419: The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel did not ensure that Thread Local Storage (TLS) descriptors are loaded before proceeding with other steps, which made it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address. - CVE-2014-9428: The batadv_frag_merge_packets function in net/batman-adv/fragmentation.c in the B.A.T.M.A.N. implementation in the Linux kernel used an incorrect length field during a calculation of an amount of memory, which allowed remote attackers to cause a denial of service (mesh-node system crash) via fragmented packets. - CVE-2014-8160: net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel generated incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allowed remote attackers to bypass intended access restrictions via packets with disallowed port numbers. - CVE-2014-9529: Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel allowed local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key. - CVE-2014-9420: The rock_continue function in fs/isofs/rock.c in the Linux kernel did not restrict the number of Rock Ridge continuation entries, which allowed local users to cause a denial of service (infinite loop, and system crash or hang) via a crafted iso9660 image. - CVE-2014-9584: The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel did not validate a length value in the Extensions Reference (ER) System Use Field, which allowed local users to obtain sensitive information from kernel memory via a crafted iso9660 image. - CVE-2014-9585: The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel did not properly choose memory locations for the vDSO area, which made it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD. - CVE-2014-8559: The d_walk function in fs/dcache.c in the Linux kernel through did not properly maintain the semantics of rename_lock, which allowed local users to cause a denial of service (deadlock and system hang) via a crafted application. - CVE-2014-8134: The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel used an improper paravirt_enabled setting for KVM guest kernels, which made it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value. Following bugs were fixed : - powerpc/pci: Fix IO space breakage after of_pci_range_to_resource() change (bnc#922542). - cifs: fix use-after-free bug in find_writable_file (bnc#909477). - usb: Do not allow usb_alloc_streams on unconfigured devices (bsc#920581). - fuse: honour max_read and max_write in direct_io mode (bnc#918954). - switch iov_iter_get_pages() to passing maximal number of pages (bnc#918954). - bcache: fix a livelock in btree lock v2 (bnc#910440) (bnc#910440).

(CVE-2015-3636, Moderate) * An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four. (CVE-2015-1593, Low) * A flaw was found in the way the Linux kernel's 32-bit emulation implementation handled forking or closing of a task with an 'int80' entry. A local user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-2830, Low) * It was found that the Linux kernel's TCP/IP protocol suite implementation for IPv6 allowed the Hop Limit value to be set to a smaller value than the default one. An attacker on a local network could use this flaw to prevent systems on that network from sending or receiving network packets. (CVE-2015-2922, Low) These updated kernel packages also include numerous bug fixes and one enhancement. Space precludes documenting all of these changes in this advisory. For information on the most significant of these changes, users are directed to the following article on the Red Hat Customer Portal : https://access.redhat.com/articles/1506133 All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement. The system must be rebooted for this update to take effect.
