========================================================================== Ubuntu Security Notice USN-1671-1 December 19, 2012
linux vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
Summary:
The system could be made to crash under certain conditions.
Software Description: - linux: Linux kernel
Details:
A flaw was discovered in the Linux kernel's handling of new hot-plugged memory. An unprivileged local user could exploit this flaw to cause a denial of service by crashing the system.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.10: linux-image-3.5.0-21-generic 3.5.0-21.32 linux-image-3.5.0-21-highbank 3.5.0-21.32 linux-image-3.5.0-21-omap 3.5.0-21.32 linux-image-3.5.0-21-powerpc-smp 3.5.0-21.32 linux-image-3.5.0-21-powerpc64-smp 3.5.0-21.32
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.
