USN-2282-1: Linux kernel vulnerabilities

16 July 2014

linux vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 10.04 LTS


Several security issues were fixed in the kernel.

Software Description

  • linux - Linux kernel


Sasha Levin reported a flaw in the Linux kernel’s point-to-point protocol (PPP) when used with the Layer Two Tunneling Protocol (L2TP). A local user could exploit this flaw to gain administrative privileges. (CVE-2014-4943)

An flaw was discovered in the Linux kernel’s audit subsystem when auditing certain syscalls. A local attacker could exploit this flaw to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS). (CVE-2014-3917)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 10.04 LTS
linux-image-2.6.32-64-386 - 2.6.32-64.128
linux-image-2.6.32-64-generic - 2.6.32-64.128
linux-image-2.6.32-64-generic-pae - 2.6.32-64.128
linux-image-2.6.32-64-ia64 - 2.6.32-64.128
linux-image-2.6.32-64-lpia - 2.6.32-64.128
linux-image-2.6.32-64-powerpc - 2.6.32-64.128
linux-image-2.6.32-64-powerpc-smp - 2.6.32-64.128
linux-image-2.6.32-64-powerpc64-smp - 2.6.32-64.128
linux-image-2.6.32-64-preempt - 2.6.32-64.128
linux-image-2.6.32-64-server - 2.6.32-64.128
linux-image-2.6.32-64-sparc64 - 2.6.32-64.128
linux-image-2.6.32-64-sparc64-smp - 2.6.32-64.128
linux-image-2.6.32-64-versatile - 2.6.32-64.128
linux-image-2.6.32-64-virtual - 2.6.32-64.128

To update your system, please follow these instructions:

After a standard system update you need to reboot your computer to make all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
