CVE-2022-31001

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.
