CWE-476  (opens in a new tab)

How to fix?

Upgrade Centos:6 wireshark-devel to version 0:1.8.10-4.el6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark-devel package and not the wireshark-devel package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The IsDFP_Frame function in plugins/profinet/packet-pn-rt.c in the PROFINET Real-Time dissector in Wireshark 1.10.x before 1.10.1 does not validate MAC addresses, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted packet.
