Amazon Linux 2023 : openssl, openssl-devel, openssl-fips-provider-latest (ALAS2023-2026-1406)

critical Nessus Plugin ID 298108

Synopsis

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

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1406 advisory.

 A flaw was found in OpenSSL. A remote attacker can exploit a stack buffer overflow vulnerability by supplying a crafted Cryptographic Message Syntax (CMS) message with an oversized Initialization Vector (IV) when parsing AuthEnvelopedData structures that use Authenticated Encryption with Associated Data (AEAD) ciphers such as AES-GCM. This can lead to a crash, causing a Denial of Service (DoS), or potentially allow for remote code execution. (CVE-2025-15467)

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 openssl --releasever 2023.10.20260202' or or 'dnf update --advisory ALAS2023-2026-1406 --releasever 2023.10.20260202' to update your system.
