CVE-2023-52892

Publication date 27 June 2024

Last updated 2 April 2025

Ubuntu priority

Medium

Why this priority?

In phpseclib before 1.0.22, 2.x before 2.0.46, and 3.x before 3.0.33, some characters in Subject Alternative Name fields in TLS certificates are incorrectly allowed to have a special meaning in regular expressions (such as a + wildcard), leading to name confusion in X.509 certificate host verification.
