CVE-2015-0204

Description

The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct RSA-to-EXPORT_RSA downgrade attacks and facilitate brute-force decryption by offering a weak ephemeral RSA key in a noncompliant role, related to the "FREAK" issue. NOTE: the scope of this CVE is only client code based on OpenSSL, not EXPORT_RSA issues associated with servers or other TLS implementations.

Tenable Responds to CVE-2015-0204: FREAK Vulnerability

Published: 2015-03-05

It seems that in recent history, the SSL library continues to give security teams plenty of opportunities to interface with systems/application administrators and vendors to upgrade SSL in their environments. The latest vulnerability to impact SSL is CVE-2015-0204, known in the media as "FREAK," short for Factoring RSA EXPORT Keys. FREAK can facilitate a man-in-the-middle attack and force a browser to export a weak 512-bit key, which can be factored in just a few hours.
