(Bugzilla: Unauthorized access and information disclosure)

    Bugzilla allows any user to modify the flags of any bug
    (CAN-2005-2173). Bugzilla inserts bugs into the database before marking
    them as private, in connection with MySQL replication this could lead
    to a race condition (CAN-2005-2174).
  
Impact :

    By manually changing the URL to process_bug.cgi, a remote attacker
    could modify the flags of any given bug, which could trigger an email
    including the bug summary to be sent to the attacker. The race
    condition when using Bugzilla with MySQL replication could lead to a
    short timespan (usually less than a second) where the summary of
    private bugs is exposed to all users.
  
Workaround :

    There are no known workarounds at this time."
