This update has been rated as having important security impact by the Red
Hat Security Response Team.

Description

Mailman is software to help manage email discussion lists.

A flaw in the true_path function of Mailman was discovered. A remote
attacker who is a member of a private mailman list could use a carefully
crafted URL and gain access to arbitrary files on the server. The Common
