========================================================================== Ubuntu Security Notice USN-2259-1 June 27, 2014 linux 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: Linux kernel Details: Salva Peiró discovered an information leak in the Linux kernel's media- device driver. A local attacker could exploit this flaw to obtain sensitive information from kernel memory. (CVE-2014-1739) A bounds check error was discovered in the socket filter subsystem of the Linux kernel. A local user could exploit this flaw to cause a denial of service (system crash) via crafted BPF instructions. (CVE-2014-3144) A remainder calculation error was discovered in the socket filter subsystem of the Linux kernel. A local user could exploit this flaw to cause a denial of service (system crash) via crafted BPF instructions. (CVE-2014-3145) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: linux-image-3.2.0-65-generic 3.2.0-65.98 linux-image-3.2.0-65-generic-pae 3.2.0-65.98 linux-image-3.2.0-65-highbank 3.2.0-65.98 linux-image-3.2.0-65-omap 3.2.0-65.98 linux-image-3.2.0-65-powerpc-smp 3.2.0-65.98 linux-image-3.2.0-65-powerpc64-smp 3.2.0-65.98 linux-image-3.2.0-65-virtual 3.2.0-65.98 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.
