Peercast procConnectArgs function buffer overflow

peercast-url-bo (25113) The risk level is classified as HighHigh Risk

Description:

Peercast is vulnerable to a stack-based buffer overflow, caused by improper bounds checking of the user supplied input by the procConnectArgs function in servmgr.cpp. By sending a specially-crafted HTTP GET request with an overly long parameter, a remote attacker could overflow a buffer and execute arbitrary code on the system.
