CVE-2022-24786: Debian Linux

Critical severity, CVSS 9.8. EPSS: 2.1% chance of exploitation in the next 30 days.

PJSIP is a free and open source multimedia communication library written in C. PJSIP versions 2.12 and prior do not parse incoming RTCP feedback RPSI (Reference Picture Selection Indication) packet, but any app that directly uses pjmedia_rtcp_fb_parse_rpsi() will be affected. A patch is available in the `master` branch of the `pjsip/pjproject` GitHub repository. There are currently no known workarounds.

Affected products

• Debian Debian Linux: version 9.0 only; version 10.0 only
• Pjsip Pjsip: up to and including 2.12
