Description

Richard Moore discovered that NSS would sometimes incorrectly match an SSL certificate which had a Common Name that used a wildcard followed by a partial IP address. While it is very unlikely that a Certificate Authority would issue such a certificate, if an attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. (CVE-2010-3170)

Nelson Bolyard discovered a weakness in the Diffie-Hellman Ephemeral mode (DHE) key exchange implementation which allowed servers to use a too small key length. (CVE-2010-3173)
