Stack-based buffer overflow in the HTTP::getAuthUserPass function (core/common/http.cpp) in Peercast 0.1218 and gnome-peercast allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a Basic Authentication string with a long (1) username or (2) password.
Heap-based buffer overflow in the handshakeHTTP function in servhs.cpp in PeerCast 0.1217 and earlier, and SVN 344 and earlier, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long SOURCE request.
Peercast places a cleartext password in a query string, which might allow attackers to obtain sensitive information by sniffing the network, or obtaining Referer or browser history information.
Multiple stack-based buffer overflows in the procConnectArgs function in servmgr.cpp in PeerCast before 0.1217 allow remote attackers to execute arbitrary code via an HTTP GET request with a long (1) parameter name or (2) value in a URL, which triggers the overflow in the nextCGIarg function in servhs.cpp.
