Description
Wireshark is a program for monitoring network traffic. Wireshark was
previously known as Ethereal.
Multiple buffer overflow flaws were found in the Wireshark SigComp

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-2010-2286)
Users of Wireshark should upgrade to these updated packages, which contain
