Wireshark is a program for monitoring network traffic. Wireshark was
previously known as Ethereal.

An array index error, leading to a stack-based buffer overflow, was
found in the Wireshark ENTTEC dissector. If Wireshark read a malformed
packet off a network or opened a malicious dump file, it could crash
or, possibly, execute arbitrary code as the user running Wireshark.
(CVE-2010-4538)

Users of Wireshark should upgrade to these updated packages, which
contain a backported patch to correct this issue. All running
instances of Wireshark must be restarted for the update to take
