wolfSSL CyaSSL before 2.9.4 allows remote attackers to cause a denial of service (NULL pointer dereference) via (1) a request for the peer certificate when a certificate parsing failure occurs or (2). Rated medium severity (CVSS 5.0), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
wolfSSL CyaSSL before 2.9.4 does not properly validate X.509 certificates with unknown critical extensions, which allows man-in-the-middle attackers to spoof servers via crafted X.509 certificate. Rated medium severity (CVSS 5.8), this vulnerability is remotely exploitable. No vendor patch available.
The TLS and DTLS implementations in wolfSSL CyaSSL before 2.5.0 do not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable. No vendor patch available.
yaSSL CyaSSL before 2.0.8 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted X.509 certificate. Rated medium severity (CVSS 5.0), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
