System Requirements for Patching
Before you start patching, allow your system to access http://crl3.digicert.com and http://crl4.digicert.com on the Software Vulnerability Research host machine to create patching packages.
Important:If your organization allows specific URL access to the Internet, and you are having problems downloading or verifying a patch, ensure the CRLs are allowed; examine the logs to identify the download's source, and examine the certificate at that address for its CRL distribution points.
