Wireshark 1.0.4 fixes the following vulnerabilities:

• Florent Drouin and David Maciejak of Fortinet's FortiGuard Global Security Research Team independently discovered that the Bluetooth ACL dissector could crash or abort. (Bug )
  Versions affected: 0.99.2 to 1.0.3
• The Q.931 dissector could crash or abort. (Bug )

• Wireshark could abort while reading Tamos CommView capture files. (Bug )
  Versions affected: 0.99.7 to 1.0.3
• David Maciejak found that the USB dissector could crash or abort. This led to the discovery of a similar problem in the Bluetooth RFCOMM dissector. (Bug )
  Versions affected: 0.99.7 to 1.0.3
• Vivek Gupta and David Maciejak found that the PRP and MATE dissectors could make Wireshark crash. (Neither PRP nor MATE are enabled by default.) (Bug ) Versions affected: 0.99.2 to 1.0.3

Impact

It may be possible to make Wireshark crash by injecting a series of malformed packets onto the wire or by convincing someone to read a malformed packet trace file.

Resolution

Upgrade to Wireshark 1.0.4 or later. Due to the nature of the bugs, there is no workaround for previous versions.
