Hi,

The following vulnerabilities were published for sofia-sip.

CVE-2022-31001[0]:
| 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.

CVE-2022-31003[2]:
| Sofia-SIP is an open-source Session Initiation Protocol (SIP) User-
| Agent library. Prior to version 1.13.8, when parsing each line of a
| sdp message, `rest = record + 2` will access the memory behind `\0`
| and cause an out-of-bounds write. An attacker can send a message with
| evil sdp to FreeSWITCH, causing a crash or more serious consequence,
| such as remote code execution. Version 1.13.8 contains a patch for
| this issue.
