Ubuntu alert USN-1743-1 (linux-lts-quantal)
========================================================================== Ubuntu Security Notice USN-1743-1 February 22, 2013 linux-lts-quantal vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS Summary: The system could be made to run programs as an administrator. Software Description: - linux-lts-quantal: Linux hardware enablement kernel from Quantal Details: Suleiman Souhlal, Salman Qazi, Aaron Durbin and Michael Davidson discovered a race condition in the Linux kernel's ptrace syscall. An unprivileged local attacker could exploit this flaw to run programs as an administrator. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: linux-image-3.5.0-25-generic 3.5.0-25.38~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.
