CVE-2015-7744

CVE-2015-7744 affects wolfSSL (formerly CyaSSL) before 3.6.8. The flaw is in handling faults during the CRT-based RSA key exchange when performing ephemeral key exchange on servers with limited memory, enabling remote attackers to extract private RSA keys from TLS handshakes (Lenstra attack). Pub...

CVE-2015-7744

wolfSSL formerly CyaSSL before 3.6.8 does not properly handle faults associated with the Chinese Remainder Theorem CRT process when allowing ephemeral key exchange without low memory optimizations on a server, which makes it easier for remote attackers to obtain private RSA keys by capturing TLS...

CVE-2014-2899

CVE-2014-2899 affects CyaSSL (wolfSSL) prior to 2.9.4. The issue enables remote denial of service via a NULL pointer dereference in two paths: (1) a certificate parsing failure when processing the peer certificate, and (2) a client_key_exchange path when the ephemeral key is not found. The NVD en...
