Summary
OpenSSL vulnerabilities were disclosed on January 8, 2015 by the OpenSSL
Project. This includes FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL
client and server vulnerability. OpenSSL is used by Rational Build Forge.
Build Forge has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2015-0204
DESCRIPTION: A vulnerability in the OpenSSL ssl3_get_key_exchange function
could allow a remote attacker to downgrade the security of certain TLS
connections. An OpenSSL client accepts the use of an RSA temporary key in a
non-export RSA key exchange ciphersuite. This could allow a remote attacker
using man-in-the-middle techniques to facilitate brute-force decryption of
TLS/SSL traffic between vulnerable clients and servers.
This vulnerability is also known as the FREAK attack.
CVSS Base Score: 4.3
