ORDR Security Bulletin - OpenSSLv3
- Which OpenSSL v3 versions are affected by CVE-2022-3602 and CVE-2022-3786?
- OpenSSL v3.0.0 through v3.0.6 contain critical remote code execution and denial-of-service vulnerabilities. ORDR's security bulletin identifies the specific affected versions and recommends immediate patching to v3.0.7 or later to close these attack vectors.
- How do buffer overflow exploits work in OpenSSL v3?
- The vulnerabilities exploit buffer overflow conditions in OpenSSL v3's X.509 certificate verification logic, allowing attackers to execute remote code or trigger denial-of-service conditions. ORDR details the specific attack mechanisms to help security teams understand exposure across their IoT and OT environments.
- What's the fastest way to prioritize OpenSSL patching across my infrastructure?
- ORDR recommends prioritizing patches based on asset criticality and external exposure first, then addressing internal-only systems. The security bulletin provides actionable guidance to systematically remediate vulnerabilities across your connected asset inventory without operational disruption.
