EulerOS Virtualization 2.13.0 : bind (EulerOS-SA-2026-2395)

high Nessus Plugin ID 320706

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 If a BIND resolver is performing DNSSEC validation and encounters a maliciously crafted zone, the resolver may consume excessive CPU. Authoritative-only servers are generally unaffected, although there are circumstances where authoritative servers may make recursive queries (see: https://kb.isc.org/docs/why- does-my-authoritative-server-make-recursive-queries).This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.46, 9.20.0 through 9.20.20, 9.21.0 through 9.21.19, 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.46-S1, and 9.20.9-S1 through 9.20.20-S1.(CVE-2026-1519)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization bind security advisory.

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

Solution

Update the affected bind packages.
