Several vulnerabilities have been discovered in Mozilla’s Network Security Services (NSS) library. The Common Vulnerabilities and Exposures project identifies the following problems :
CVE-2010-3170 NSS recognizes a wildcard IP address in the subject’s Common Name field of an X.509 certificate, which might allow man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.
CVE-2010-3173 NSS does not properly set the minimum key length for Diffie-Hellman Ephemeral (DHE) mode, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack.
