Adobe's emergency patch for Reader and Acrobat is here

Adobe has released the emergency update for Reader and Acrobat that it promised late last week.

The company decided to get a move on to deal with a newly-reported vulnerability that was actively being exploited, at least on Windows and the Mac.

The timeline has been pretty swift:

    2012-02-12: Bug reported in a blog post by FireEye. Details scant.
    2013-02-13: Adobe publishes a security bulletin, including a workaround for Windows users.
    2013-02-17: (Weekend) Adobe announces patch "next week."
    2013-02-20: Patch is released.

The fixes are available for all affected platforms, so Windows, Mac and Linux users should all upgrade.
