CVE-2023-0666 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream wireshark-cli package and not the wireshark-cli package as distributed by RHEL.
Due to failure in validating the length provided by an attacker-crafted RTPS packet, Wireshark version 4.0.5 and prior, by default, is susceptible to a heap-based buffer overflow, and possibly code execution in the context of the process running Wireshark.
