CVE-2022-31001 Information

Description

Sofia-SIP is an open-source Session Initiation Protocol (SIP) User-Agent library. Prior to version 1.13.8 an attacker can send a message with evil sdp to FreeSWITCH which may cause 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]). Version 1.13.8 contains a patch for this issue.
