========================================================================== Ubuntu Security Notice USN-1411-1 March 27, 2012 linux vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 10.04 LTS Summary: The system could be made to crash under certain conditions. Software Description: - linux: Linux kernel Details: Louis Rilling discovered a flaw in Linux kernel's clone command when CLONE_IO is specified. An unprivileged local user could exploit this to cause a denial of service. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 10.04 LTS: linux-image-2.6.32-40-386 2.6.32-40.87 linux-image-2.6.32-40-generic 2.6.32-40.87 linux-image-2.6.32-40-generic-pae 2.6.32-40.87 linux-image-2.6.32-40-ia64 2.6.32-40.87 linux-image-2.6.32-40-lpia 2.6.32-40.87 linux-image-2.6.32-40-powerpc 2.6.32-40.87 linux-image-2.6.32-40-powerpc-smp 2.6.32-40.87 linux-image-2.6.32-40-powerpc64-smp 2.6.32-40.87 linux-image-2.6.32-40-preempt 2.6.32-40.87 linux-image-2.6.32-40-server 2.6.32-40.87 linux-image-2.6.32-40-sparc64 2.6.32-40.87 linux-image-2.6.32-40-sparc64-smp 2.6.32-40.87 linux-image-2.6.32-40-versatile 2.6.32-40.87 linux-image-2.6.32-40-virtual 2.6.32-40.87 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.
