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.
