1109034: CVE-2014-4020 wireshark: Frame metadissector crash (wnpa-sec-2014-07)

The MITRE CVE dictionary describes this issue as:

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.
