Mandriva Linux Security Advisory 2009-197 – 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.
