The Adobe patches fix the problem in each product. But wouldn't the defense in depth changes in Internet Explorer in KB972260 block the exploits? My googling is failing to find where somebody has actually tested this and published their findings.

There are two separate issues here.

First is the Microsoft ATL issue. Not sure if the defense in depth in KB972260 blocks attacks or not. The ATL issue affects Shockwave and Flash. My personal opinion is that you fix everything - belt and suspenders is best! Maybe someone finds a workaround for 972260, but if you have Flash and Shockwave patched then you're at least fine on those two. Note that, according to Adobe, Reader and Acrobat were unaffected by ATL.

Second issue is the Authplay.dll vulnerability, which is a zero-day that's been known for almost two weeks. This is present in both Flash and Adobe Reader/Acrobat and is, AFAIK, independent of the ATL issue.

Releases: Shockwave was updated on Tuesday (addressing ATL), Flash was updated (addressing both ATL and Authplay) on Thursday, and Reader/Acrobat were updated today (addressing Authplay).

Short answer? GET PATCHING!
One more note - if you have Firefox deployed en masse, according to it appears that 3.5.2 will be a chemspill release due sometime on Monday!
