Overview

Several security issues were fixed in the kernel.

Releases

Packages

Details

Salva Peiró discovered an information leak in the Linux kernel's media-
device driver. A local attacker could exploit this flaw to obtain sensitive
information from kernel memory. (CVE-2014-1739)

A bounds check error was discovered in the socket filter subsystem of the
Linux kernel. A local user could exploit this flaw to cause a denial of
service (system crash) via crafted BPF instructions. (CVE-2014-3144)

A remainder calculation error was discovered in the socket filter subsystem
of the Linux kernel. A local user could exploit this flaw to cause a denial
of service (system crash) via crafted BPF instructions. (CVE-2014-3145)

Update instructions

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

Learn more about how to get the fixes.

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.

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

Ubuntu Release Package Version
12.04 precise linux-image-3.2.0-65-highbank –  3.2.0-65.98
linux-image-3.2.0-65-virtual –  3.2.0-65.98
linux-image-3.2.0-65-powerpc64-smp –  3.2.0-65.98
linux-image-3.2.0-65-generic-pae –  3.2.0-65.98
linux-image-3.2.0-65-omap –  3.2.0-65.98
linux-image-3.2.0-65-generic –  3.2.0-65.98
linux-image-3.2.0-65-powerpc-smp –  3.2.0-65.98
