Software Description: - linux: Linux kernel Details: A flaw was found in KVM's Programmable Interval Timer (PIT). When a virtual interrupt control is not available a local user could use this to cause a denial of service by starting a timer. (CVE-2011-4622) A flaw was discovered in the XFS filesystem. If a local user mounts a specially crafted XFS image it could potential execute arbitrary code on the system. (CVE-2012-0038) Andy Whitcroft discovered a that the Overlayfs filesystem was not doing the extended permission checks needed by cgroups and Linux Security Modules (LSMs). A local user could exploit this to by-pass security policy and access files that should not be accessible. (CVE-2012-0055) A flaw was found in the linux kernels IPv4 IGMP query processing. A remote attacker could exploit this to cause a denial of service. (CVE-2012-0207) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: linux-image-3.0.0-16-generic 3.0.0-16.28 linux-image-3.0.0-16-generic-pae 3.0.0-16.28 linux-image-3.0.0-16-omap 3.0.0-16.28 linux-image-3.0.0-16-powerpc 3.0.0-16.28 linux-image-3.0.0-16-powerpc-smp 3.0.0-16.28 linux-image-3.0.0-16-powerpc64-smp 3.0.0-16.28 linux-image-3.0.0-16-server 3.0.0-16.28 linux-image-3.0.0-16-virtual 3.0.0-16.28 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.
