Debian DSA-5438-1 : asterisk - security update

high Nessus Plugin ID 177573

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5438 advisory.

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 the oldstable distribution (bullseye), this problem has been fixed in version 1:16.28.0~dfsg-0+deb11u3. We recommend that you upgrade your asterisk packages. For the detailed security status of asterisk please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/asterisk

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the asterisk packages.
