CyberRota Analysis

AI-Generated

Suricata versions prior to 7.0.16 and 8.0.5 are vulnerable to a denial of service attack due to insufficient bounds in certain NFS parser state structures, which can lead to excessive memory consumption when processing crafted NFS traffic. Organizations utilizing Suricata for network intrusion detection or prevention should prioritize updating to the patched versions or disabling NFS application-layer parsing if it is not required for their operations. This vulnerability poses a significant risk, particularly for environments heavily reliant on NFS traffic.

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, certain NFS parser state structures were insufficiently bounded. Crafted NFS traffic may cause Suricata to consume excessive memory, potentially resulting in denial of service. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, disable NFS application-layer parsing if it is not needed.
