EulerOS Virtualization 2.11.0 : dhcp (EulerOS-SA-2026-3496)

high Nessus Plugin ID 348068

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the dhcp package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

Resolver caches and authoritative zone databases that hold significant numbers of RRs for the same hostname (of any RTYPE) can suffer from degraded performance as content is being added or updated, and also when handling client queries for this name.(CVE-2024-1737)

If a server hosts a zone containing a 'KEY' Resource Record, or a resolver DNSSEC-validates a 'KEY' Resource Record from a DNSSEC-signed domain in cache, a client can exhaust resolver CPU resources by sending a stream of SIG(0) signed requests.(CVE-2024-1975)

It is possible to construct a zone such that some queries to it will generate responses containing numerous records in the Additional section. An attacker sending many such queries can cause either the authoritative server itself or an independent resolver to use disproportionate resources processing the queries. Zones will usually need to have been deliberately crafted to attack this exposure.This issue affects BIND 9 versions 9.11.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.32, 9.20.0 through 9.20.4, 9.21.0 through 9.21.3, 9.11.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.50-S1, and 9.18.11-S1 through 9.18.32-S1.(CVE-2024-11187)

Under certain circumstances, BIND is too lenient when accepting records from answers, allowing an attacker to inject forged data into the cache.This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1.(CVE-2025-40778)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization dhcp 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

Update the affected dhcp packages.
