There's a new JS vulnerability in Adobe Acrobat and Reader, according to ComputerWorld [computerworld.com]. It's going to go in the wild within a day or two. You might want to protect yourself.

To disable JavaScript in Adobe Reader or Acrobat on Windows, users must select Preferences from the Edit menu, choose "JavaScript," then uncheck the "Enable Acrobat JavaScript" option. (On the Mac, Preferences is under the "Adobe Reader" or "Adobe Acrobat" menus.)

Turning off JavaScript may be the only defense against attack until Adobe patches the problem. And it may be nearly a month before that happens: Adobe's next regularly-scheduled security updates for Reader/Acrobat are to ship Jan. 12, 2010.
