============================================================================ Ubuntu Security Notice USN-1499-1 July 09, 2012 linux-ti-omap4 vulnerability ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.10 Summary: The system could be made to crash if it received specially crafted network traffic. Software Description: - linux-ti-omap4: Linux kernel for OMAP4 Details: A flaw was discovered in the Linux kernel's NFSv4 (Network file system) handling of ACLs (access control lists). A remote NFS server (attacker) could cause a denial of service (OOPS). Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: linux-image-3.0.0-1212-omap4 3.0.0-1212.24 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.
