Key Boundary Confusion

wolfssl is vulnerable to Key Boundary Confusion attack. The vulnerability is due to wolfSSL failing to enforce boundaries between DTLS messages handled by different keys, allowing for the amalgamation of messages meant for different security contexts into a single record...

Marvin Attack

wolfssl is vulnerable to Marvin Attack. The vulnerability is due to the implementation of the RSA cipher within the wolfSSL library, when Enables static RSA cipher suites using the "--enable-all" option and the "-DWOLFSSLSTATICRSA" CFLAGS option.It allows an attacker to decrypt ciphertexts and...

CVE-2023-3724

This CVE (CVE-2023-3724) describes a TLS 1.3 client-side issue where, if a server is malicious and the client sends neither a PSK nor a KSE, a default, potentially known, IKM buffer is used to generate the session master secret. The root cause is a mishandled IKM when PSK/KSE are absent, which ca...
