Adobe to patch critical flaws in Reader and Acrobat
Adobe will release a number of critical security patches today for both Windows and Mac users with Reader and Acrobat.


Adobe will today patch a number of critical flaws in both its Reader and Acrobat offerings.
The flaws, which affect both Windows and Mac users, are considered "critical security issues" and include an earlier noted issue in Adobe's Flash Player, allowing the possibility to subvert the domain sandbox and make unauthorised cross-domain requests.
The updates will affect Adobe Reader 9.3 for Windows, Mac and UNIX, Adobe Acrobat 9.3, Adobe Reader 8.2 and Acrobat 8.2 for Windows and Mac.
It is the third patch from Adobe in less than two months following critical vulnerabilities in Shockwave and the introduction of the Auto Updater.
As ever, Adobe recommends that all its users update to the latest versions of its products to keep themselves better protected.
