============================================================================ Ubuntu Security Notice USN-1849-1 May 31, 2013 linux-lts-raring vulnerability ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS Summary: The system could be made to crash or run programs as an administrator if it received specially crafted network traffic. Software Description: - linux-lts-raring: Linux hardware enablement kernel from Raring 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 12.04 LTS: linux-image-3.8.0-23-generic 3.8.0-23.34~precise1 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.
