Executive Summary

This vulnerability is a crash in Wireshark's RF4CE protocol dissector affecting versions 4.6.0 to 4.6.8 and 4.4.0 to 4.4.18. It occurs due to improper handling of malformed packets, causing Wireshark to crash when processing such packets or opening malicious trace files.

Detection Guidance

To detect this vulnerability, check your Wireshark version. If it is between 4.6.0 to 4.6.8 or 4.4.0 to 4.4.18, the system is vulnerable. Run 'wireshark -v' to check the installed version.

Impact Analysis

An attacker could exploit this to crash Wireshark by sending a malformed packet or tricking a user into opening a malicious packet trace file. This leads to a denial of service, disrupting network analysis and potentially causing data loss or downtime.

Compliance Impact

This vulnerability primarily causes denial of service by crashing Wireshark, which could disrupt network analysis and monitoring activities. For compliance standards like GDPR or HIPAA, which require continuous monitoring and logging of network traffic, such disruptions could lead to gaps in data protection measures or audit trails. However, the vulnerability does not directly expose or leak sensitive data.

Mitigation Strategies

Upgrade Wireshark to version 4.6.9 or later, or 4.4.19 or later. This addresses the RF4CE protocol dissector crash issue.
