CyberRota Analysis
AI-GeneratedSuricata versions 8.0.0 to 8.0.4 are vulnerable due to an unbounded storage of LDAP transaction responses, which can be exploited through crafted UDP traffic to consume excessive memory and potentially lead to a denial of service. Organizations utilizing Suricata for network security monitoring should prioritize upgrading to version 8.0.5 or implementing the recommended workarounds to mitigate this risk.

Original NVD Description
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Starting in version 8.0.0 and prior to version 8.0.5, LDAP transaction state could store an unbounded number of responses. Because LDAP can be processed over UDP, crafted traffic may cause Suricata to consume excessive memory, potentially resulting in denial of service. Version 8.0.5 contains a fix. As a workaround, disable LDAP application-layer parsing where it is not required. Alternatively, use a rule like `alert ldap any any -> any any (sid: 1; ldap.responses.count: >1024; bypass;)`.
