I was clicking around in the news today and saw Adobe announce another exploit was in the wild and they should release a patch for it next Tuesday. Again, this one is affecting versions 9.1.3 and earlier, for Linux, Mac OS and Windows.
Here’s a link to the advisory:

The patch also coincides with Microsoft’s Patch Tuesday.
In the meantime the workarounds are pretty standard. For Windows XP, disable Javascript and/or use Firefox with Noscript. For Vista and Windows 7, you can enable Data Execution Prevention (DEP)
