CVE-2014-4020

Wireshark 1.10.x < 1.10.8 - Denial of Service via Frame Metadissector Length Handling

Title source: llm

Description

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.
