PeerCast is a Peer to Peer broadcasting technology for listening to radio and watching video on the Internet.
INFIGO discovered a problem in the URL handling code. Buffers that are allocated on the stack can be overflowed inside of nextCGIarg() function.
By sending a specially crafted request to the HTTP server, a remote attacker can cause a stack overflow, resulting in the execution of arbitrary code.
There is no known workaround at this time.
All PeerCast users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-sound/peercast-0.1217"
