Synopsis

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

Description

The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5105 advisory.

 Two vulnerabilities were found in the BIND DNS server, which could result in denial of service or cache poisoning. For the oldstable distribution (buster), this problem has been fixed in version 1:9.11.5.P4+dfsg-5.1+deb10u7. For the stable distribution (bullseye), this problem has been fixed in version 1:9.16.27-1~deb11u1. We recommend that you upgrade your bind9 packages. For the detailed security status of bind9 please refer to its security tracker page at: https://security- tracker.debian.org/tracker/bind9

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 bind9 packages.

For the stable distribution (bullseye), this problem has been fixed in version 1
