wolfssl — Vulnerabilities & Security Advisories 94

wolfSSL is an embedded SSL/TLS library primarily designed for resource-constrained environments, including IoT devices, automotive systems, and embedded Linux. Its compact footprint makes it a standard choice for secure communications in hardware with limited memory and processing power. Historically, the codebase has been associated with numerous Common Vulnerabilities and Exposures, totaling 62 recorded instances. These flaws predominantly involve memory corruption issues, such as buffer overflows and use-after-free errors, which can lead to remote code execution or denial of service. While cross-site scripting is less relevant to its backend nature, improper input validation remains a recurring theme. Notable incidents often stem from complex cryptographic implementations or parsing errors in certificate handling. The project maintains an active security response process, addressing these vulnerabilities through regular updates, though the high volume of past CVEs highlights the challenges of maintaining rigorous security standards in a widely deployed, low-level cryptographic component.
