PeerCast is a client and server for P2P-radio networks.
Nico Golde reported a boundary error in the HTTP::getAuthUserPass() function when processing overly long HTTP Basic authentication requests.
A remote attacker could send a specially crafted HTTP request to the vulnerable server, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application.
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-0.1218-r1"
