Several vulnerabilities that have been discovered in the Linux kernel (OMAP4) 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, an information leak has been discovered in the handling of ICMPv6 Router Advertisement (RA) messages in the Linux kernel's IPv6 network stack. A remote attacker could have exploited this flaw to cause a denial of service (excessive retries and address-generation outage) and, consequently, obtain sensitive information

The security flaws can be fixed if you upgrade your system(s) to linux-image-3.5.0-236-omap4 (3.5.0-236.52).

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.
