EulerOS 2.0 SP15 : bind (EulerOS-SA-2026-3899)

high Nessus Plugin ID 364079

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the bind packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

It is possible for an attacker's zone to respond to a query with an RRSIG that has a smaller number of labels than the zone in which the RRSIG is contained. This causes `named` to produce a wildcard name for a zone that is shorter than the attacker's zone, which can result in cache poisoning. For this attack to have any effect, the resolver under attack must have set `synth-from-dnssec yes;` (which is the default)._x000D_ This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-S1.(CVE-2026-11721)

BIND may accept incorrect child-zone NSEC3 records as valid, which could allow an attacker to forge authenticated NXDOMAIN responses._x000D_ This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-S1.(CVE-2026-10723)

The BIND resolver accepts validly-signed NSEC records where the 'Next Domain Name' field points outside the signer's zone._x000D_ This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-S1.(CVE-2026-13321)

Tenable has extracted the preceding description block directly from the EulerOS bind 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 bind packages.
