Description Moritz Muehlenhoff univentionstaff 2015-01-09 07:22:09 CET
Denial of service in DTLS (2014-3571)

ECDHE can be downgraded to ECDH, resulting in a loss of forward secrecy (CVE-2014-3572)
Weaker RSA keys can be negotiated (CVE-2015-0204)
AFAICS these can only be exploited by a malicous server.

Certificate fingerprints can be modified (CVE-2014-8275)

Bignum squaring may produce incorrect results (CVE-2014-3570)
