USN-552-1: Perl vulnerability

4 December 2007

Perl vulnerability




It was discovered that Perl's regular expression library did not correctly
handle certain UTF sequences. If a user or automated system were tricked
into running a specially crafted regular expression, a remote attacker
could crash the application or possibly execute arbitrary code with
user privileges.

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.
