NVD Description

Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the NetScaler file parser could go into an infinite loop, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by ensuring a nonzero record size.
