CWE-20  (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 s7comm_decode_ud_cpu_szl_subfunc function in epan/dissectors/packet-s7comm_szl_ids.c in the S7COMM dissector in Wireshark 2.0.x before 2.0.1 does not validate the list count in an SZL response, which allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted packet.
