Details

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.8 and 3.2.5, OpenSIPS crashes when a malformed SDP body is sent multiple times to an OpenSIPS configuration that makes use of the stream_process function. This issue was discovered during coverage guided fuzzing of the function codec_delete_except_re. By abusing this vulnerability, an attacker is able to crash the server. It affects configurations containing functions that rely on the affected code, such as the function codec_delete_except_re. This issue has been fixed in version 3.1.8 and 3.2.5.
