CVE-2018-14340 (opens in a new tab)How to fix?
Upgrade RHEL:7 wireshark to version 0:1.10.14-24.el7 or higher.
This issue was patched in RHSA-2020:1047.
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, dissectors that support zlib decompression could crash. This was addressed in epan/tvbuff_zlib.c by rejecting negative lengths to avoid a buffer over-read.
