Ubuntu alert USN-1788-1 (linux-lts-backport-oneiric)
========================================================================== Ubuntu Security Notice USN-1788-1 April 04, 2013 linux-lts-backport-oneiric 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-lts-backport-oneiric: Linux kernel backport from Oneiric Details: Emese Revfy discovered that in the Linux kernel signal handlers could leak address information across an exec, making it possible to bypass ASLR (Address Space Layout Randomization). A local user could use this flaw to bypass ASLR to reliably deliver an exploit payload that would otherwise be stopped (by ASLR). (CVE-2013-0914) A memory use after free error was discovered in the Linux kernel's tmpfs filesystem. A local user could exploit this flaw to gain privileges or cause a denial of service (system crash). (CVE-2013-1767) Mateusz Guzik discovered a race in the Linux kernel's keyring. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-1792) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 10.04 LTS: linux-image-3.0.0-32-generic 3.0.0-32.51~lucid1 linux-image-3.0.0-32-generic-pae 3.0.0-32.51~lucid1 linux-image-3.0.0-32-server 3.0.0-32.51~lucid1 linux-image-3.0.0-32-virtual 3.0.0-32.51~lucid1 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.
