CVE-2021-31924

Affected software: Yubico pam-u2f (PAM module for FIDO2/U2F) prior to version 1.1.1. Root cause: A logic issue in pam-u2f could bypass a PIN requirement when configured to require PIN and the application allows NULL as the PIN; pam-u2f then proceeds with FIDO2 authentication without PIN. This byp...
