## Overview

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, a malicious rule could potentially overwrite any file on the file system on rule load or reload. Versions 7.0.16 and 8.0.5 fix the issue. Some workarounds are available. Preprocess `load`+ `save` rules to disallow absolute filenames for save, use Suricata's privilege dropping to limit writable files, and/or configure landlock in suricata.yaml.

## Affected

- `suricata >= 7.0.0, < 7.0.16`
- `suricata >= 8.0.0, < 8.0.5`

## Remediation

Upgrade past the affected range:

- `suricata 8.0.5`
