Potential heap buffer overflow when parsing DNS packets in PJSIP
Résumé
Potential heap buffer overflow when parsing DNS packets in PJSIP
Description d'origine
La description telle que publiée par la source (souvent en anglais).
PJSIP is a free and open source multimedia communication library written in C. A buffer overflow vulnerability in versions 2.12 and prior affects applications that use PJSIP DNS resolution. It doesn't affect PJSIP users who utilize an external resolver. This vulnerability is related to CVE-2023-27585. The difference is that this issue is in parsing the query record parse_rr(), while the issue in CVE-2023-27585 is in parse_query(). A patch is available in the master branch of the pjsip/pjproject GitHub repository. A workaround is to disable DNS resolution in PJSIP config (by setting nameserver_count to zero) or use an external resolver instead.
