========================================================================== Ubuntu Security Notice USN-1844-1 May 30, 2013

linux vulnerability

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

  • Ubuntu 12.04 LTS


The system could be made to crash or run programs as an administrator if it received specially crafted network traffic.

Software Description: - linux: Linux kernel


Kees Cook discovered a flaw in the Linux kernel's iSCSI subsystem. A remote unauthenticated attacker could exploit this flaw to cause a denial of service (system crash) or potentially gain administrative privileges.

Update instructions:

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

Ubuntu 12.04 LTS: linux-image-3.2.0-45-generic 3.2.0-45.70 linux-image-3.2.0-45-generic-pae 3.2.0-45.70 linux-image-3.2.0-45-highbank 3.2.0-45.70 linux-image-3.2.0-45-omap 3.2.0-45.70 linux-image-3.2.0-45-powerpc-smp 3.2.0-45.70 linux-image-3.2.0-45-powerpc64-smp 3.2.0-45.70 linux-image-3.2.0-45-virtual 3.2.0-45.70

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.
