wolfSSL Inc. — Vulnerabilities & Security Advisories 5

wolfSSL provides embedded SSL/TLS libraries for IoT devices and resource-constrained systems. Historically, vulnerabilities have included buffer overflows, use-after-free errors, and improper input validation, which could lead to remote code execution or denial of service. The company maintains a moderate CVE count of five, with no major public security incidents reported. wolfSSL emphasizes FIPS 140-2 validation and supports legacy protocols for compatibility, though this may introduce potential attack surfaces. Regular security updates and a focus on memory safety in their C codebase help mitigate risks, though the complexity of cryptographic implementations remains a challenge for embedded security.
