10 Kernel Vulnerabilities in Ubuntu 6.06, 8.04, 8.10, 9.04 and 9.10

“Canonical announced a few hours ago the immediate availability
of a new Linux kernel security update for the following Ubuntu
distributions: 6.06 LTS (Dapper Drake), 8.04 LTS (Hardy Heron),
8.10 (Intrepid Ibex), 9.04 (Jaunty Jackalope) and 9.10 (Karmic
Koala). 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.”
