Details

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 machine-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)
