Amazon Linux 2023 : bind, bind-chroot, bind-devel (ALAS2023-2026-1533)
high Nessus Plugin ID 304615
Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1533 advisory.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 tested product security advisory.
