Adobe Reader 9.2 has been released. (download links below)
Not only Microsoft released a bunch of patches to close security holes in their products, but also Adobe now ships updated software to fix several vulnerabilities in Adobe Reader and Acrobat which already
get attacked with specially prepared PDF documents to take over control of vulnerable computers.
Users of Adobe Reader and Acrobat with earlier versions than the new 9.2 are advised to install the updated software immediately to protect themselves from the attacks; Adobe rates the vulnerabilities as critical.
New versions of Reader are available for Windows, Mac and Unix. Further links for updates for different Acrobat versions are listed in Adobes
security advisory.
