NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the DICOM dissector could go into a large or infinite loop. This was addressed in epan/dissectors/packet-dcm.c by preventing an offset overflow.
