Adobe has released a patch for two critical vulnerabilities that are already being exploited by attackers. The vulnerabilities affect Adobe Reader and Acrobat XI (11.0.01 and earlier), X (10.1.5 and earlier) and 9.5.3 and earlier for Windows and Mac OS X systems. Exploits were discovered by security company FireEye and researchers with antivirus provider Kaspersky Lab have confirmed the exploit can successfully escape the Adobe sandbox. Users can update the software through the built-in updater or by downloading a copy of the Windows, Mac, Linux installer directly from Adobe’s website.
