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, compressed HTTP data can lead to unbounded memory growth during decompression. This issue has been patched in version 8.0.2. A workaround involves disabling LZMA decompression or limiting response-body-limit size.

Executive Summary

This vulnerability in Suricata versions 8.0.0 to before 8.0.2 involves unbounded memory growth during decompression of compressed HTTP data, specifically related to LZMA decompression. This can cause the system to consume excessive memory, potentially leading to denial of service. The issue has been fixed in version 8.0.2, and workarounds include disabling LZMA decompression or limiting the response-body size.

Impact Analysis

The vulnerability can cause unbounded memory growth during decompression, which may lead to denial of service (DoS) by exhausting system resources. This can disrupt network intrusion detection and prevention capabilities, potentially allowing malicious traffic to go undetected or causing system instability.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade Suricata to version 8.0.2 or later. Alternatively, you can apply a workaround by disabling LZMA decompression or limiting the response-body-limit size in your Suricata configuration.
