Major Linux Kernel Update Issued for Ubuntu 13.10

Users have to upgrade their operating systems in order to fix the problem

Multiple vulnerabilities that have been discovered in the Linux kernel affecting the Ubuntu 13.10 (Saucy Salamander) operating system have 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 the ipv6 UDP Fragmentation Offload (UFI) in the Linux kernel. A remote attacker could exploit it to cause a denial of service (panic).

Also, an error has been discovered in the way the ath9k driver was handling the BSSID masking. A remote attacker could exploit this error to discover the original MAC address after a spoofing attack.

The security flaws can be fixed if you upgrade your system(s) to the linux-image-3.11.0-17-generic, (3.11.0-17.31).

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.
