Vault and Vault Enterprise (“Vault”) TLS certificate auth method did not correctly validate client certificates when configured with a non-CA certificate as trusted certificate. In this configuration, an attacker may be able to craft a malicious certificate that could be used to bypass authentication. Fixed in Vault 1.15.5 and 1.14.10.

Ubuntu Security Notice 6673-1 - Hubert Kario discovered that python-cryptography incorrectly handled errors returned by the OpenSSL API when processing incorrect padding in RSA PKCS#1 v1.5. A remote attacker could possibly use this issue to expose confidential or sensitive information.
