- Summary
- Potential heap buffer overflow when parsing DNS packets in PJSIP
- Details
-
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 inparse_query(). A patch is available in themasterbranch of thepjsip/pjprojectGitHub repository. A workaround is to disable DNS resolution in PJSIP config (by settingnameserver_countto zero) or use an external resolver instead. - References
