Name of the Vulnerable Software and Affected Versions Sofia-SIP versions prior to 1.13.8

Description Sofia-SIP is an open-source Session Initiation Protocol (SIP) User-Agent library. An attacker can send a message with malicious sdp to FreeSWITCH, which may cause a crash. This type of crash may be caused by #define MATCH(s, m) (strncmp(s, m, n = sizeof(m) - 1) == 0), which will make n bigger and trigger out-of-bound access when IS NON WS(s[n]).

Recommendations For versions prior to 1.13.8, update to version 1.13.8 to resolve the issue. As a temporary workaround, consider restricting the handling of sdp messages from untrusted sources until the patch is applied.
