Memory leak in mm/hugetlb.c in the Linux kernel before 3.4.2 allows local users to cause a denial of service (memory consumption or system crash) via invalid MAP_HUGETLB mmap operations.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:1150 advisory.

    The kernel-rt packages contain the Linux kernel, the core of any Linux     operating system.

    This update fixes the following security issues:

    * A memory leak flaw was found in the way the Linux kernel's memory     subsystem handled resource clean up in the mmap() failure path when the     MAP_HUGETLB flag was set. A local, unprivileged user could use this flaw to     cause a denial of service. (CVE-2012-2390, Moderate)

    * A flaw was found in the way the Linux kernel's Event Poll (epoll)     subsystem handled resource clean up when an ELOOP error code was returned.
    A local, unprivileged user could use this flaw to cause a denial of     service. (CVE-2012-3375, Moderate)

    This update also fixes the following bugs:

    * The MRG 2.1 realtime kernel lacked support for automatic memory     reservation for the kdump kernel, as present in Red Hat Enterprise Linux     kernels. Using the parameter crashkernel=auto on the kernel boot command     line led to kdump being disabled because no memory was correctly reserved.
    Support for crashkernel=auto has been implemented in the 3.0 realtime     kernel and now when the crashkernel=auto parameter is specified, machines     with more than 4GB of RAM have the amount of memory required by the kdump     kernel calculated and reserved. (BZ#820427)

    * The current bnx2x driver in the MRG 2.1 realtime kernel had faulty     support for the network adapter PCI ID 14e4:168e and did not work     correctly. The bnx2x driver was updated to include support for this network     adapter. (BZ#839037)

    Users should upgrade to these updated packages, which upgrade the kernel-rt     kernel to version kernel-rt-3.0.36-rt57, and correct these issues. The     system must be rebooted for this update to take effect.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An integer overflow flaw was found in the i915_gem_do_execbuffer() function in the Intel i915 driver in the Linux kernel. A local, unprivileged user could use this flaw to cause a denial of service.
This issue only affected 32-bit systems. (CVE-2012-2384 , Moderate)

A memory leak flaw was found in the way the Linux kernel's memory subsystem handled resource clean up in the mmap() failure path when the MAP_HUGETLB flag was set. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2390 , Moderate)

A race condition was found in the way access to inet->opt ip_options was synchronized in the Linux kernel's TCP/IP protocol suite implementation. Depending on the network facing applications running on the system, a remote attacker could possibly trigger this flaw to cause a denial of service. A local, unprivileged user could use this flaw to cause a denial of service regardless of the applications the system runs. (CVE-2012-3552 , Moderate)

A flaw was found in the way the Linux kernel's dl2k driver, used by certain D-Link Gigabit Ethernet adapters, restricted IOCTLs. A local, unprivileged user could use this flaw to issue potentially harmful IOCTLs, which could cause Ethernet adapters using the dl2k driver to malfunction (for example, losing network connectivity). (CVE-2012-2313 , Low)

A flaw was found in the way the msg_namelen variable in the rds_recvmsg() function of the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation was initialized. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space.
(CVE-2012-3430 , Low)

  - kernel: unfiltered netdev rio_ioctl access by users (CVE-2012-2313)

  - kernel: drm/i915: integer overflow in i915_gem_do_execbuffer() (CVE-2012-2384)

  - kernel: huge pages: memory leak on mmap failure (CVE-2012-2390)

  - kernel: recv{from,msg}() on an rds socket can leak kernel memory (CVE-2012-3430)

  - kernel: net: slab corruption due to improper synchronization around inet->opt (CVE-2012-3552)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An error was discovered in the Linux kernel's network TUN/TAP device implementation. A local user with access to the TUN/TAP interface (which is not available to unprivileged users until granted by a root user) could exploit this flaw to crash the system or potential gain administrative privileges. (CVE-2012-2136)

Ulrich Obergfell discovered an error in the Linux kernel's memory management subsystem on 32 bit PAE systems with more than 4GB of memory installed. A local unprivileged user could exploit this flaw to crash the system. (CVE-2012-2373)

An error was discovered in the Linux kernel's memory subsystem (hugetlb). An unprivileged local user could exploit this flaw to cause a denial of service (crash the system). (CVE-2012-2390)

A flaw was discovered in the Linux kernel's epoll system call. An unprivileged local user could use this flaw to crash the system.
(CVE-2012-3375)

Some errors where discovered in the Linux kernel's UDF file system, which is used to mount some CD-ROMs and DVDs. An unprivileged local user could use these flaws to crash the system. (CVE-2012-3400)

A flaw was discovered in the madvise feature of the Linux kernel's memory subsystem. An unprivileged local use could exploit the flaw to cause a denial of service (crash the system). (CVE-2012-3511).

(CVE-2012-2136)

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2372)

An error was discovered in the Linux kernel's memory subsystem (hugetlb). An unprivileged local user could exploit this flaw to cause a denial of service (crash the system). (CVE-2012-2390).

Update to Linux 2.6.43.8 (3.3.8).

Disabled 32bit NX emulation. Suspected of being broken and it deviates from upstream.

Unless there are further security issues, this will likely be the last F15 kernel update before End-of-Life. The 3.3.7 stable kernel contains a number of important bug fixes

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Linux v3.3.8

Fixes for CVE-2012-2390 and CVE-2012-2372. Disabled 32bit NX emulation which is suspected of being broken and aligns us more with upstream.

Final 3.3.x update before rebasing to the 3.4 kernel series.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The 3.4 kernel contains a large number of bug fixes

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote CentOS system is missing a security update which has been documented in Red Hat advisory RHSA-2012-1304.
