Description
Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions from 8.0.0 to before 8.0.2, a NULL dereference can occur when the entropy keyword is used in conjunction with base64_data. This issue has been patched in version 8.0.2. A workaround involves disabling rules that use entropy in conjunction with base64_data.

Executive Summary

This vulnerability in Suricata versions 8.0.0 to before 8.0.2 involves a NULL pointer dereference that occurs when the entropy keyword is used together with base64_data. This can cause the program to crash or behave unexpectedly. The issue has been fixed in version 8.0.2, and a temporary workaround is to disable rules that use entropy with base64_data.

Impact Analysis

The vulnerability can cause Suricata to crash or become unavailable due to a NULL dereference, leading to denial of service (DoS). This impacts the availability of the network intrusion detection and prevention system, potentially leaving the network unmonitored or unprotected.

Mitigation Strategies

To mitigate this vulnerability, upgrade Suricata to version 8.0.2 or later. As a workaround before upgrading, disable rules that use the entropy keyword in conjunction with base64_data.
