      feature. (Bug 2392)
      Versions affected: 0.99.6 to 0.99.8 

Impact

It may be possible to make Wireshark crashby injecting a purposefully
malformed packet onto the wire or by convincing someone to read a
malformed packet trace file.

Resolution

Upgrade to Wireshark 1.0.0 or later.

If are running Wireshark 0.99.8 or earlier and cannot upgrade, you can
work around each of the problems listed above by doing the following:

    * Disable the LDAP, Roofnet, and X.509sat dissectors:
          o Select Analyze?Enabled Protocols... from the menu.
          o Make sure "LDAP," "Roofnet," and "X509SAT" are un-checked.
          o Click "Save", then click "OK".
