PeerCast handshakeHTTP function buffer overflow
| peercast-handshakehttp-bo (39075) |  High Risk |
Description:
PeerCast is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the handshakeHTTP function. By sending an overly long request to the handshakeHTTP function, a local attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
