Several invalid HTTPS certificates were placed on the certificate
blacklist to prevent their misuse.

Users on a compromised network could be directed to sites using
the fraudulent certificates and mistake them for the legitimate
sites. This could deceive them into revealing personal information
such as usernames and passwords. It may also deceive users into
downloading malware if they believe it's coming from a trusted site.

The NSS and NSPR packages were updated to the latest versions as
well as the rootcerts packages providing the latest root CA certs
from mozilla as of 2011/03/23.

The firefox packages were updated to the latest 3.6.16 version which
is not vulnarable to this issue.

The mozilla thunderbird 3.1.9 packages were patched with the same
fix as of firefox as a precaution.

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:
