Impact

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

Resolution

Upgrade to Wireshark 0.99.7.

If are running Wireshark 0.99.6 or Ethereal 0.99.0 or earlier and cannot upgrade, you can work around each of the problems listed above by doing the following:

• Disable the HTTP, DCP ETSI, SSL, DHCP/BOOTP, and MMS dissectors.
  • Select Analyze→Enabled Protocols... from the menu.
  • Make sure "ANSI MAP", "BTSDP", "DCP (ETSI)", "DNP 3.0", "FB/IPB GDS DB", "HTTP", "MEGACO", "NCP", "PPP", "SSL" are un-checked.
  • Click "Save", then click "OK".
