CWE-189  (opens in a new tab)

How to fix?

Upgrade wireshark to version 1.10.8 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). 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.
