Extracted from above link: Affected software versions:
Adobe Reader 7.0.0 through 7.0.8 and Adobe Acrobat Standard and Professional 7.0.0 through 7.0.8 on the Windows platform when using Internet Explorer. Users of other browsers are not affected.
...........The vulnerability is in an ActiveX control used by Internet Explorer; users of other browsers are not affected. The following workaround will prevent these vulnerabilities from occurring in Adobe Reader 7.0.X on Windows using Internet Explorer:
Exit Internet Explorer and Adobe Reader. Browse to volume>:\Program Files\Adobe\Acrobat 7.0\ActiveX. Note: If you did not install Acrobat to the default location, browse to the location of your Acrobat 7.0 folder. Select AcroPDF.dll and delete it. NOTE: This workaround will prevent PDF documents from opening within an Internet Explorer window. After applying this workaround, clicking on PDF files within Internet Explorer will either open in a separate instance of Adobe Reader or the user will be prompted to download the file, which can then be opened in Adobe Reader. This workaround may disrupt some enterprise workflows and use of PDF forms
