USN-842-1: Wget vulnerability

6 October 2009

Wget vulnerability




It was discovered that Wget did not correctly handle SSL certificates with
zero bytes in the Common Name. A remote attacker could exploit this to
perform a machine-in-the-middle attack to view sensitive information or alter
encrypted communications.

Update instructions

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

Ubuntu 9.04
Ubuntu 8.10
Ubuntu 8.04
Ubuntu 6.06

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