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 2.6.4 and 2.4.0 to 2.4.10, the MMSE dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-mmse.c by preventing length overflows.
