------------------------------------------------------------------------- Debian LTS Advisory DLA-3394-1 [email protected] https://www.debian.org/lts/security/ Markus Koschany April 19, 2023 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

Package : asterisk Version : 1:16.28.0~dfsg-0+deb10u3 CVE ID : CVE-2023-27585

A flaw was found in Asterisk, an Open Source Private Branch Exchange. A buffer overflow vulnerability affects users that use 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 workaround is to disable DNS resolution in PJSIP config (by setting `nameserver_count` to zero) or use an external resolver implementation instead.

For Debian 10 buster, this problem has been fixed in version 1:16.28.0~dfsg-0+deb10u3.

We recommend that you upgrade your asterisk packages.
