Amazon Linux 2023 Security Advisory: ALAS2023-2026-1406
Advisory Released Date: 2026-02-05
Advisory Updated Date: 2026-02-05
Severity:
Important
Issue Overview:
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)
Affected Packages:
openssl
Issue Correction:
Run dnf update openssl --releasever 2023.10.20260202 or dnf update --advisory ALAS2023-2026-1406 --releasever 2023.10.20260202 to update your system.
