========================================================================== Ubuntu Security Notice USN-2176-1 April 26, 2014 linux-lts-raring vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - linux-lts-raring: Linux hardware enablement kernel from Raring Details: A flaw was discovered in the Kernel Virtual Machine (KVM) subsystem of the Linux kernel. A guest OS user could exploit this flaw to execute arbitrary code on the host OS. (CVE-2014-0049) Al Viro discovered an error in how CIFS in the Linux kernel handles uncached write operations. An unprivileged local user could exploit this flaw to cause a denial of service (system crash), obtain sensitive information from kernel memory, or possibly gain privileges. (CVE-2014-0069) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: linux-image-3.8.0-39-generic 3.8.0-39.57~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.
