NVD Description

Note: Versions mentioned in the description apply only to the upstream pjproject package and not the pjproject package as distributed by Ubuntu. See How to fix? for Ubuntu:18.04 relevant fixed versions and status.

PJSIP is a free and open source multimedia communication library written in C. A buffer overflow vulnerability in versions 2.13 and prior affects applications that use PJSIP DNS resolver. It doesn't affect PJSIP users who do not utilise PJSIP DNS resolver. This vulnerability is related to CVE-2022-24793. The difference is that this issue is in parsing the query record parse_query(), while the issue in CVE-2022-24793 is in parse_rr(). A patch is available as commit d1c5e4d in the master branch. A workaround is to disable DNS resolution in PJSIP config (by setting nameserver_count to zero) or use an external resolver implementation instead.
