CVE-2015-0205
Last modified
CVE-2015-0205 is a vulnerability of currently unknown severity. The ssl3_get_cert_verify function in s3_srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k accepts client authentication with a Diffie-Hellman (DH) certificate without requiring a CertificateVerify message, which allows remote attackers to obtain access without knowledge of a private key via crafted TLS Handshake Protocol traffic to a server that recognizes a Certification Authority with DH support.. EPSS estimates a 24.63% chance of exploitation in the next 30 days.
