OpenSSL: Remote code execution or Denial of Service via oversized Initialization Vector in CMS parsing
CVE: CVE-2025-15467
Component: openssl
CWE: CWE-120
Severity: Important
CVSS v3: 9.8/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Release date: 2025-01-01T00:00:00+00:00

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.

Statement: This vulnerability is rated Important for Red Hat products. On Red Hat Enterprise Linux, OpenSSL is built with stack protections enabled which mitigate the risk of code execution though a denial-of-service condition remains possible. This vulnerability only affects applications and services that parse untrusted CMS or PKCS#7 content using AEAD ciphers, such as Kerberos using the PKINIT plugin. OpenSSL versions 1.1.1 and 1.0.2 are not affected by this issue.
