FreeBSD Security Advisory FreeBSD-SA-00:57 - The muh port, an IRC bouncer, versions 2.05c and below contains a vulnerability which allows remote users to gain the privileges of the user running muh. This is accomplished by sending a carefully crafted exploit string containing string format operators to a user using muh but who is not connected. When the user reconnects and executes '/muh read', muh will allow the remote attacker to execute arbitrary code as the local user.
