Software Company Adobe has warned the users of their Acrobat and Acrobat Reader applications about critical un-patched bugs.

These bugs are serious enough to let hackers take control of computers using Windows Operating System running Internet Explorer web browser.

These security bugs have been labeled critical by the software company. Adobe said that the problem exists in the AcroPDF ActiveX control, which is a component present in both Adobe Acrobat and Adobe Reader applications.

This control enables the user to view PDF files within the Internet Explorer browser. However, users who prefer to use alternative browsers like Opera and Firefox are safe from this bug. Adobe further said that they are working on a patch, which would be included in Acrobat and Reader updates in the coming days.
