Oisf

Oisf maintains Suricata, a widely deployed open-source network intrusion detection and prevention engine that sits in line with traffic inspection and threat monitoring workloads across both enterprise and specialized security deployments. Despite a narrow product portfolio, the vendor's prominence in the security landscape derives from Suricata's deep integration into network monitoring infrastructure and its role as a foundational component in threat-detection pipelines. Vulnerabilities affecting the vendor center on resource-handling and memory-safety issues—including unbounded resource consumption, out-of-bounds writes, and NULL-pointer dereferences—that reflect the demands of high-performance packet processing and protocol parsing in a C-based codebase. The recurring exposure across Suricata itself and its companion tools such as libhtp and update utilities underscores the breadth of the attack surface introduced by a protocol-heavy engine exposed to untrusted network input. Live severity and exploitation counts are shown alongside this summary.
