Just got word that one of yesterday’s patch Tuesday flaws was a critical vulnerability in CAPICOM. We have been big CAPICOM advocates as it enables IE to do some great PKI stuff, and now it is time to get it patched.

We’re going to be alerting customers as soon as we get good lists of who is using it, but in the meantime, check out the link above and update yourself if you think you might have installed CAPICOM or used a website that uses it.
