(PAM-MySQL: Multiple vulnerabilities)

    A flaw in handling the result of pam_get_item() as well as further
    unspecified flaws were discovered in PAM-MySQL.
  
Impact :

    By exploiting the mentioned flaws an attacker can cause a Denial of
    Service and thus prevent users that authenticate against PAM-MySQL from
    logging into a machine. There is also a possible additional attack
    vector with more malicious impact that has not been confirmed yet.
  
Workaround :

    There is no known workaround at this time."
