All Precise Pangolin users are urged to update their systems!
A few days ago, Canonical has announced in a security notice that a new Linux kernel update is available for its Ubuntu 12.04 LTS (Precise Pangolin) operating system, fixing eight vulnerabilities found in the Linux kernel packages.These are the eight kernel vulnerabilities found in the kernel packages for Ubuntu 12.04 LTS (Precise Pangolin): CVE-2013-1059, CVE-2013-1060, CVE-2013-2164, CVE-2013-2232, CVE-2013-2234, CVE-2013-2851, CVE-2013-4162, and CVE-2013-4163.
As usual, you can click on each one to see how it affects your system, or go here for in-depth descriptions, as it affects other Linux operating systems as well.
These security flaws can be fixed if you upgrade your system(s) to the linux-image-3.2.0-53 (3.2.0-53.81) package(s). To apply the update, run the Update Manager application.
Don't forget to reboot your computer after the upgrade! Ubuntu 12.10, Ubuntu 13.04 and Ubuntu 10.04 LTS also received kernel updates, so make sure you keep your systems up-to-date.
