CVE-2015-0204

MEDIUM 4.3EPSS 98.7%

Does this matter?

EPSS puts the probability of exploitation in the next 30 days at 98.7%, higher than 100% of all known CVEs. Patch or mitigate before the next change window.

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.
