Ubuntu 13.10 Gets a Linux Kernel Update to Fix Security Issues

Users have been advised to upgrade as soon as possible

A vulnerability that has been discovered in the Linux kernel affecting the Ubuntu 13.10 (Saucy Salamander) operating system has been announced by Canonical.

According to the company, several security issues have been fixed in the kernel.

For example, a flaw has been found in how the permissions for network sysctls are handled in the Linux kernel. An unprivileged local user could exploit this flaw to have privileged access to files in proc/sys/net/.

The security flaws can be fixed if you upgrade your system(s) to linux-image-3.11.0-14 (3.11.0-14.21).

Don't forget to reboot your computer after the upgrade!

ATTENTION: Due to an unavoidable ABI change, the kernel packages have a new version number, which will force you to reinstall and recompile all third-party kernel modules you might have installed. Moreover, if you use the linux-restricted-modules package, you have to update it as well to get modules that work with the new Linux kernel version.
