Where can I find a list of un-patched CVEs for a specific piece of software?
MS Exchange 2003 is no longer supported by Microsoft since April 2009.
However the Exchange 2003 server that I currently have is working just fine for me.
Is there a list of exploits in Exchange 2003 that are not patchable, so that I can make an informed decision on whether I need to upgrade urgently or not?
Links to unofficial patches to fix holes after the last security pack are also much appreciated.
