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.

For the stable distribution (lenny), these problems have been fixed in version 3.12.3.1-0lenny2.

For the unstable distribution (sid) and the upcoming stable distribution (squeeze), these problems have been fixed in version 3.12.8-1.

We recommend that you upgrade your NSS packages.");
