Adobe's Acrobat and Acrobat Reader packages are currently under attack from a JavaScript-based exploit, similar to one which afflicted the software back in June.

Adobe acknowledged that all versions of Reader and Acrobat contain at least one critical vulnerability.

Adobe, although they have admitted to the flaw, has not given a time line for fixing the affected applications with include Acrobat (Reader as well) 9.1, 8.1.4, 7.1.1 and earlier.
