CVE-2023-0465  (opens in a new tab)
CWE-295  (opens in a new tab)

How to fix?

Upgrade openssl to version 1.1.1u, 3.0.9, 3.1.1 or higher.

Overview

Affected versions of this package are vulnerable to Improper Certificate Validation due to invalid certificate policies in leaf certificates are silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A malicious CA could use this to deliberately assert invalid certificate policies to circumvent policy checking on the certificate altogether.

Note: Exploiting this vulnerability is possible on applications that use a non-default option when verifying certificates.
