OISF — Vulnerabilities & Security Advisories 55

Browse all 55 CVE security advisories affecting OISF. AI-powered Chinese analysis, POCs, and references for each vulnerability.

The Open Information Security Foundation (OISF) develops and maintains Suricata, an open-source network intrusion detection and prevention system widely deployed for real-time traffic analysis. With fifty-five recorded Common Vulnerabilities and Exposures, the organization’s software has historically been susceptible to remote code execution, buffer overflow, and denial-of-service flaws, often stemming from complex packet parsing logic. These vulnerabilities occasionally allow attackers to crash the service or execute arbitrary commands on affected hosts. While no catastrophic data breaches directly attributed to OISF have been publicly documented, the high volume of CVEs highlights the inherent risks in maintaining large-scale, C-based security infrastructure. The foundation addresses these issues through regular updates and community-driven patching, emphasizing transparency in its security response process.
