Multiple vulnerabilities that have 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. Check the report to see the extent of the upgrade.

For example, a flaw has been reported in the Linux kernel's per event subsystem that allows normal users to enable function tracing. An unprivileged local user could exploit this flaw to obtain potentially Sensitive information from the kernel.

The security flaws can be fixed if you upgrade your system(s) to the linux-image-3.11.0-15-generic, (3.11.0-15.23).

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.
