Flaw in vBulletin add-on leads to Ubuntu Forums database breach

Ubuntu support forums users should be on the lookout for dodgy emails after the website’s database of 2 million email addresses was stolen. Canonical announced the security breach on Friday after being notified that someone was claiming to have a copy of the UbuntuForums.org database. An investigation revealed that an attacker did get access to the website’s user records through a vulnerability.
