Impact
It may be possible to make Ethereal crash, use up available memory, or
run arbitrary code by injecting a purposefully malformed packet onto the
wire or by convincing someone to read a malformed packet trace file.

Resolution
Upgrade to Wireshark 0.99.2.

If are running Ethereal 0.99.0 or earlier and cannot upgrade, you can disable each
of the dissectors listed above by doing the following:

     * Select Analyze→Enabled Protocols... from the menu.
     * Make sure every protocol listed above is un-checked.
     * Click "Save", then click "OK".
