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 September 10 2013 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 versions are:
- Adobe Reader XI (11.0.03) and earlier 11.x versions for Windows and Macintosh
- Adobe Reader X (10.1.7) and earlier 10.x versions for Windows and Macintosh
- Adobe Acrobat XI (11.0.03) and earlier 11.x versions for Windows and Macintosh
- Adobe Acrobat X (10.1.7) and earlier 10.x versions for Windows and Macintosh
