New Kernel Vulnerability Affects Ubuntu 13.10

All Saucy Salamander users are urged to update their systems immediately!

On January 30, Canonical announced in a security notice that a new Linux kernel update was available for its Ubuntu 13.10 (Saucy Salamander) operating system, fixing a security issue found recently in the Linux kernel packages.

It was discovered that pageexec reported a bug in the Linux kernel's recvmsg syscall when it was called from code using the x32 ABI, which could allow an unprivileged local user to cause a DoS (Denial of Service) attack or gain root privileges.

More information about this Linux kernel security issue can be found in the CVE-2014-0038 reference and it affects other Linux operating systems as well.

The security flaw can be fixed if you upgrade your Ubuntu 13.10 system(s) to the linux-image-3.11.0-15 (3.11.0-15.25) package(s). To apply the update, run the Update Manager application and install all the available updates, or read the instructions provided by Canonical at

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