Details

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

• libperl5.8 - 5.8.8-7ubuntu3.1

Ubuntu 7.04

• libperl5.8 - 5.8.8-7ubuntu0.1

Ubuntu 6.10

Ubuntu 6.06

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