Title:	Debian: Security Advisory (DLA-3394-1)
Summary:	The remote host is missing an update for the Debian 'asterisk' package(s) announced via the DLA-3394-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'asterisk' package(s) announced via the DLA-3394-1 advisory. Vulnerability Insight: 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.
