Adobe has updated its Adobe Reader software (used to view PDF files) and Acrobat software for Windows and Macintosh to “address vulnerabilities that could cause a crash and potentially allow an attacker to take control of the affected system”.
Such vulnerabilities in Adobe Reader (and Acrobat) before December 9 2014 could allow for execution of unwanted code (typically installing malware or viruses/worms on your PC), without your consent just by opening a PDF.
The affected software versions of Adobe Reader and Acrobat are
- Adobe Reader XI (11.0.09) and earlier 11.x versions
- Adobe Reader X (10.1.12) and earlier 10.x versions
- Adobe Acrobat XI (11.0.09) and earlier 11.x versions
- Adobe Acrobat X (10.1.12) and earlier 10.x versions
