"The remote Bugzilla bug tracking system, according to its version
number, is vulnerable to various flaws :

- An administrator may be able to execute arbitrary SQL
    commands on
    the remote host.

- There are instances of information leaks that may let an
    attacker
    know the database password (under certain circumstances,
    2.17.x only)
    or obtain the names of otherwise hidden products.

- A user with grant membership privileges may escalate his
    privileges
    and belong to another group.

- There is a cross-site scripting issue in the
    administrative web
    interface.

- Users passwords may be embedded in URLs (2.17.x only).

- Several information leaks exist that may allow users to
    determine the
    names of other users and non-users to obtain a list of
    products,
    including those that administrators might want to keep
    confidential.");
