CVE-2015-0205  (opens in a new tab)
CWE-310  (opens in a new tab)

How to fix?

Upgrade openssl to version 1.0.0p, 1.0.1k or higher.

Overview

Affected versions of this package are vulnerable to Cryptographic Issues. 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.
