============================================================================ Ubuntu Security Notice USN-1554-1 September 05, 2012 linux vulnerability ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.10 Summary: The system could be made to crash under certain conditions. Software Description: - linux: Linux kernel Details: A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation. A local, unprivileged user could use this flaw to cause a denial of service. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: linux-image-3.0.0-25-generic 3.0.0-25.41 linux-image-3.0.0-25-generic-pae 3.0.0-25.41 linux-image-3.0.0-25-omap 3.0.0-25.41 linux-image-3.0.0-25-powerpc 3.0.0-25.41 linux-image-3.0.0-25-powerpc-smp 3.0.0-25.41 linux-image-3.0.0-25-powerpc64-smp 3.0.0-25.41 linux-image-3.0.0-25-server 3.0.0-25.41 linux-image-3.0.0-25-virtual 3.0.0-25.41 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.
