Prior to commit a1b707c, a stack buffer overflow exists in the SRTP\/SDES media transport when processing a=crypto attributes during SDP offer\/answer (sdes_encode_sdp() in transport_srtp_sdes.c). This affects applications with SRTP enabled (use_srtp optional or mandatory, using SDES keying). During media negotiation, the crypto attributes from the remote SDP are collected into a fixed-size array without bounding their number; a remote peer that includes an excessive number of a=crypto attributes in a single media description can write past the end of that array on the stack. This is reachable from an incoming SIP INVITE during offer\/answer, before application-level authentication. Impact may range from unexpected application termination to control flow hijack\/memory corruption. Applications that do not enable SRTP are not affected.
