The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5734 advisory.
- ------------------------------------------------------------------------- Debian Security Advisory DSA-5734-1 [email protected] https://www.debian.org/security/ Salvatore Bonaccorso July 25, 2024 https://www.debian.org/security/faq
- -------------------------------------------------------------------------
Package : bind9 CVE ID : CVE-2024-0760 CVE-2024-1737 CVE-2024-1975 CVE-2024-4076
Several vulnerabilities were discovered in BIND, a DNS server implementation, which may result in denial of service.
To mitigate CVE-2024-1737 two new configuration statements have been added to allow operators of secondary servers and recursive resolvers to set an upper bound on the growth of data in their zones or caches.
Details can be found at:
https://kb.isc.org/docs/rrset-limits-in-zones
For the oldstable distribution (bullseye), these problems have been fixed in version 1:9.16.50-1~deb11u1. For the oldstable distribution (bullseye) the limits to mitigate CVE-2024-1737 are hardcoded and not configurable.
For the stable distribution (bookworm), these problems have been fixed in version 1:9.18.28-1~deb12u1.
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
Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/

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.
