========================================================================== Ubuntu Security Notice USN-2415-1 November 25, 2014 linux vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 10.04 LTS Summary: The system could be made to deny write access to files. Software Description: - linux: Linux kernel Details: Andy Lutomirski discovered that the Linux kernel was not checking the CAP_SYS_ADMIN when remounting filesystems to read-only. A local user could exploit this flaw to cause a denial of service (loss of writability). Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 10.04 LTS: linux-image-2.6.32-68-386 2.6.32-68.135 linux-image-2.6.32-68-generic 2.6.32-68.135 linux-image-2.6.32-68-generic-pae 2.6.32-68.135 linux-image-2.6.32-68-ia64 2.6.32-68.135 linux-image-2.6.32-68-lpia 2.6.32-68.135 linux-image-2.6.32-68-powerpc 2.6.32-68.135 linux-image-2.6.32-68-powerpc-smp 2.6.32-68.135 linux-image-2.6.32-68-powerpc64-smp 2.6.32-68.135 linux-image-2.6.32-68-preempt 2.6.32-68.135 linux-image-2.6.32-68-server 2.6.32-68.135 linux-image-2.6.32-68-sparc64 2.6.32-68.135 linux-image-2.6.32-68-sparc64-smp 2.6.32-68.135 linux-image-2.6.32-68-versatile 2.6.32-68.135 linux-image-2.6.32-68-virtual 2.6.32-68.135 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.
