(*): ISC rating
- We use 4 levels:
- PATCH NOW: Typically used where we see immediate danger of exploitation. Typical environments will want to deploy these patches ASAP. Workarounds are typically not accepted by users or are not possible. This rating is often used when typical deployments make it vulnerable and exploits are being used or easy to obtain or make.
- Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.
- Important: Things where more testing and other measures can help.
- Less Urgent: Typically we expect the impact if left unpatched to be not that big a deal in the short term. Do not forget them however.
- The difference between the client and server rating is based on how you use the affected machine. We take into account the typical client and server deployment in the usage of the machine and the common measures people typically have in place already. Measures we presume are simple best practices for servers such as not using outlook, MSIE, word etc. to do traditional office or leisure work.
- The rating is not a risk analysis as such. It is a rating of importance of the vulnerability and the perceived or even predicted threat for affected systems. The rating does not account for the number of affected systems there are. It is for an affected system in a typical worst-case role.
- Only the organization itself is in a position to do a full risk analysis involving the presence (or lack of) affected systems, the actually implemented measures, the impact on their operation and the value of the assets involved.
- All patches released by a vendor are important enough to have a close look if you use the affected systems. There is little incentive for vendors to publicize patches that do not have some form of risk to them

Under the FAQ for MS10-028 it indicates -
Microsoft Office Visio 2002 and later versions have a built-in feature that prompts a user to Open, Save, or Cancel before opening a document. This mitigating factor reduces the remote code execution vulnerability from Critical to Important because the vulnerability requires more than a single user action to complete the exploit.

Which one, if any, does MS10-022 really replaces?

In pentests we sometimes get the fun of playing with client side attacks using PDFs, so far it has successfully worked in every one.
Users will click OK if it gets them what they think they want. So to me saying that the risk is reduced because the user has to open it is relying on the weakest control ever, the user. True it is slightly less risky that a fully automated exploit, but this will be used in targeted attacks.

According to http://technet.microsoft.com/en-us/security/cc998259.aspx an exploitability index of 1 is the highest possible.
Some social engineering is required for these attacks, but as can be seen in a recent PDF attack often this is not hard (even with typos), see http://www.sophos.com/blogs/sophoslabs/?p=9308
