The update also applies to Kubuntu, Edubuntu and Xubuntu and it patches 10 important security issues (see below for details) discovered in the Linux kernel packages by various hackers. Therefore, it is strongly recommended to update your system as soon as possible!

"The following Linux kernel vulnerabilities were discovered:

"1. The EXT4 and HFS filesystems failed to check various disk structures. Because of this, a remote attacker could trick a user into mounting a specially devised filesystem and could crash the affected system or gain root (system administrator) privileges. The issue was discovered by Amerigo Wang and Eric Sesterhenn and affects all the aforementioned Ubuntu systems.

"2. FUSE (Filesystem in Userspace) failed to check various requests."
