Description

Wireshark 1.6.1 fixes the following vulnerabilities:

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 1.6.1 or later. Although you can disable the ANSI MAP dissector it is not possible to work around the Lucent/Ascend parser bug.
