Security issues in nss prior to 3.12.3 could lead to a man-in-the-middle attack via a spoofed X.509 certificate and md2 algorithm flaws , and also cause a denial-of-service and possible code execution via a long domain name in X.509 certificate . This update provides the latest versions of NSS and NSPR libraries which are not vulnerable to those attacks. Update: Packages for 2008.0 are being provided due to extended support for Corporate products.
