CVE-2022-31003: Debian Linux

Critical severity, CVSS 9.8. EPSS: 3.8% 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, 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.

Affected products

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