CyberRota Analysis
AI-GeneratedSuricata versions prior to 7.0.16 and 8.0.5 are vulnerable to a heap buffer overflow triggered by crafted rules with mixed-case frame syntax during the signature loading process. This vulnerability does not require malicious network traffic to exploit, potentially compromising the integrity of the system. Organizations using Suricata for network security should prioritize updating to the patched versions or implement workarounds to mitigate the risk.

Original NVD Description
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 crafted rule using mixed-case frame syntax could trigger a heap buffer overflow while Suricata is loading signatures. The issue is reached during rule parsing/loading rather than by network traffic alone. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, preprocess rules to check that frames are all lowercase and/or only load trusted rulesets.
