CVE-2022-31001: Debian Linux

High severity, CVSS 7.5. EPSS: 2.1% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 10.0 only; version 11.0 only
• Signalwire Sofia-SIP: before 1.13.8 (fixed in 1.13.8)
