Amazon Linux 2023 : buildah (ALAS2023-2026-3326)

medium Nessus Plugin ID 371906

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-3326 advisory.

Due to security concerns regarding a small set of intermediate certificates issued by a specific Certificate Authority (CA), the Go's crypto/x509 package is updated to not trust certificates issued by the affected intermediate certificates. This would prevent possible future misuse of certificate issued by the affected intermediate certificates. (CVE-2026-111943)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'dnf update buildah --releasever 2023.12.20261026' or or 'dnf update --advisory ALAS2023-2026-3326 --releasever 2023.12.20261026' to update your system.
