How to fix?

Upgrade wireshark to version 1.6.3 or higher.

Overview

Affected versions of this package are vulnerable to Resource Management Errors. The csnStreamDissector function in epan/dissectors/packet-csn1.c in the CSN.1 dissector in Wireshark 1.6.x before 1.6.3 does not initialize a certain variable, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.
