CVE-2014-4020  (opens in a new tab)
CWE-189  (opens in a new tab)

How to fix?

Upgrade Ubuntu:14.04 wireshark to version 2.6.3-1~ubuntu14.04.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

The dissect_frame function in epan/dissectors/packet-frame.c in the frame metadissector in Wireshark 1.10.x before 1.10.8 interprets a negative integer as a length value even though it was intended to represent an error condition, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.
