3. Description:

Wireshark is a network protocol analyzer. It is used to capture and browse
the traffic running on a computer network.

Multiple flaws were found in Wireshark. 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-2014-6429, CVE-2014-6430, CVE-2014-6431, CVE-2014-6432)

Several denial of service flaws were found in Wireshark. Wireshark could
crash or stop responding if it read a malformed packet off a network, or
opened a malicious dump file. (CVE-2014-6421, CVE-2014-6422, CVE-2014-6423,
CVE-2014-6424, CVE-2014-6425, CVE-2014-6426, CVE-2014-6427, CVE-2014-6428)

All wireshark users are advised to upgrade to these updated packages, which
