7.9 - USN-1846-1

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

- Ubuntu 12.10

Summary:

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

Details:

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 12.10:
linux-image-3.5.0-32-generic 3.5.0-32.53
linux-image-3.5.0-32-highbank 3.5.0-32.53
linux-image-3.5.0-32-omap 3.5.0-32.53
linux-image-3.5.0-32-powerpc-smp 3.5.0-32.53
linux-image-3.5.0-32-powerpc64-smp 3.5.0-32.53

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.
