发布于3月6日3月6日 Members Debian: CVE-2023-27585: asterisk, ring -- security update Severity 8 CVSS (AV:N/AC:L/Au:N/C:N/I:N/A:C) Published 03/14/2023 Created 05/05/2023 Added 04/20/2023 Modified 01/30/2025 Description 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.
