Description
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.
Affected configurations
• opensips opensips (< 3.1.8)
• opensips opensips (>= 3.2.0 < 3.2.5)
