Wireshark: wnpa-sec-2008-01


Name: Multiple problems in Wireshark (formerly Ethereal) versions
      0.6.0 to 0.99.7
Docid: wnpa-sec-2008-01
Date: February 27, 2008
Versions affected: 0.6.0 up to and including 0.99.7


Wireshark 0.99.8 fixes the following vulnerabilities:
    * The SCTP dissector could crash.
      Versions affected: 0.99.5 to 0.99.7
    * The SNMP dissector could crash. (Bugs 2144 and 2277)
      Versions affected: 0.99.6 to 0.99.7
    * The TFTP dissector could crash Wireshark on Ubuntu 7.10. (This 
      appears to be a bug in the Cairo library on that platform.)
      Reported by Noam Rathaus.
      Versions affected: 0.6.0 to 0.99.7
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

Upgrade to Wireshark 0.99.8.
If are running Wireshark 0.99.7 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 SCTP, SNMP and TFTP dissectors.
          o Select Analyze?Enabled Protocols... from the menu.
          o Make sure "SCTP," "SNMP," and "TFTP" are un-checked.
          o Click "Save", then click "OK".
