## Description

epan/dissectors/packet-wcp.c in the WCP dissector in Wireshark 1.10.x
before 1.10.14 and 1.12.x before 1.12.5 improperly refers to previously
processed bytes, which allows remote attackers to cause a denial of service
(application crash) via a crafted packet, a different vulnerability than
CVE-2015-2188.
