Clement Lecigne discovered a bug in the HFS filesystem. A local attacker could exploit this to cause a kernel oops. A flaw was found in how the Linux kernel handles user-defined key types. An unprivileged local user could exploit this to crash the system. Updated packages are available from security.ubuntu.com.
========================================================================== Ubuntu Security Notice USN-1344-1 January 24, 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: Clement Lecigne discovered a bug in the HFS filesystem. A local attacker could exploit this to cause a kernel oops. (CVE-2011-2203) A flaw was found in how the Linux kernel handles user-defined key types. An unprivileged local user could exploit this to crash the system. (CVE-2011-4110) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 10.04 LTS: linux-image-2.6.32-38-386 2.6.32-38.83 linux-image-2.6.32-38-generic 2.6.32-38.83 linux-image-2.6.32-38-generic-pae 2.6.32-38.83 linux-image-2.6.32-38-ia64 2.6.32-38.83 linux-image-2.6.32-38-lpia 2.6.32-38.83 linux-image-2.6.32-38-powerpc 2.6.32-38.83 linux-image-2.6.32-38-powerpc-smp 2.6.32-38.83 linux-image-2.6.32-38-powerpc64-smp 2.6.32-38.83 linux-image-2.6.32-38-preempt 2.6.32-38.83 linux-image-2.6.32-38-server 2.6.32-38.83 linux-image-2.6.32-38-sparc64 2.6.32-38.83 linux-image-2.6.32-38-sparc64-smp 2.6.32-38.83 linux-image-2.6.32-38-versatile 2.6.32-38.83 linux-image-2.6.32-38-virtual 2.6.32-38.83 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.
