Acrobat and Acrobat Reader, two of the most widely used desktop applications, contain serious security flaws that could be used to take over a system, according to Adobe. The company urged users to update the software immediately.
Adobe Reader is Adobe's tool for reading PDF (Portable Document Format) files, while Acrobat can also create PDF files and has other more advanced features. Affected are Reader and Acrobat versions 5.1, 6.0 to 6.0.3, and 7.0 to 7.0.2. Users can update to versions 5.2, 6.0.4 or 7.0.3 via the software's built-in automatic update or via a manual download from Adobe's site.
