Package: mailman
Vulnerability: local mailman group exploit
Debian-specific: no

Former versions of mailman v2.0 came with a security problem, introduced during the 2.0 beta cycle, that could be exploited by clever local users to gain group mailman permission. No exploit does exist at the moment, though.
