24 March 2008

bzip2 vulnerability




It was discovered that bzip2 did not correctly handle certain malformed
archives. If a user or automated system were tricked into processing
a specially crafted bzip2 archive, applications linked against libbz2
could be made to crash, possibly leading to a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.10
Ubuntu 7.04
Ubuntu 6.10
Ubuntu 6.06

In general, a standard system upgrade is sufficient to effect the
necessary changes.
