Missing some critical patches from Microsoft

I have a question about the Altiris Patch Mgmt solution for Windows.

Special note:  I do not have the additional pieces for the client management suite, I only have patch management.

I am missing critical updates from Microsoft.  They are KB articles (not the MS13-0xxx type updates).

Here are two examples:

kb2685813
kb2685811

What is different about these KB's I listed above that they would not show up within Altiris patch mangement for Windows?

Is there some type of description that explains exactly what updates are provided from Microsoft vs the ones that are not provided?  I can get these through WSUS but not Altiris and I don't understand what the differences are between one update and another.

Thank you,

Scott
