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 RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the SIGCOMP dissector could crash. This was addressed in epan/dissectors/packet-sigcomp.c by correcting the extraction of the length value.
