Summary
Juthawong Naisanguansee discovered that PAM incorrectly cleared failed
login attempt records when certain services invoked the account phase
without first performing authentication. An attacker could possibly use
this issue to reset failed login counters, resulting in authentication
lockout restrictions being bypassed.
