Ubuntu alert USN-1535-1 (linux)
========================================================================== Ubuntu Security Notice USN-1535-1 August 10, 2012 linux vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 10.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: An error was discovered in the Linux kernel's network TUN/TAP device implementation. A local user with access to the TUN/TAP interface (which is not available to unprivileged users until granted by a root user) could exploit this flaw to crash the system or potential gain administrative privileges. (CVE-2012-2136) An error was discovered in the Linux kernel's memory subsystem (hugetlb). An unprivileged local user could exploit this flaw to cause a denial of service (crash the system). (CVE-2012-2390) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 10.04 LTS: linux-image-2.6.32-42-386 2.6.32-42.95 linux-image-2.6.32-42-generic 2.6.32-42.95 linux-image-2.6.32-42-generic-pae 2.6.32-42.95 linux-image-2.6.32-42-ia64 2.6.32-42.95 linux-image-2.6.32-42-lpia 2.6.32-42.95 linux-image-2.6.32-42-powerpc 2.6.32-42.95 linux-image-2.6.32-42-powerpc-smp 2.6.32-42.95 linux-image-2.6.32-42-powerpc64-smp 2.6.32-42.95 linux-image-2.6.32-42-preempt 2.6.32-42.95 linux-image-2.6.32-42-server 2.6.32-42.95 linux-image-2.6.32-42-sparc64 2.6.32-42.95 linux-image-2.6.32-42-sparc64-smp 2.6.32-42.95 linux-image-2.6.32-42-versatile 2.6.32-42.95 linux-image-2.6.32-42-virtual 2.6.32-42.95 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.
