Acrobat and Reader for Windows and Mac have been updated to address 3 vulnerabilities. At least one of these vulnerabilities gets priority 1 from Adobe, which they define as one which is "...being targeted, or which ha[s] a higher risk of being targeted, by exploit(s) in the wild for a given product version and platform. Adobe recommends administrators install the update as soon as possible. (for example, within 72 hours)."
The new versions of Adobe Reader and Acrobat X and XI are 10.1.9 and 11.0.06. The quickest way to update is with the Help > Check for Updates feature.
Adobe has also updated Flash Player for Windows, Macintosh and Linux, as well as Adobe AIR and the AIR SDK and Compiler. The vulnerabilities fixed in these updates could allow an attacker to bypass Flash security protections and take control of the system.
The new Flash Player 12 versions are 18.104.22.168 (for Mac and Windows with Internet Explorer); 22.214.171.124 for all versions of Chrome; and 126.96.36.199 for all NPAPI-based browsers (such as Firefox). Flash Player 11 has been updated to 11.7.700.260 for Windows and Mac and to 188.8.131.525 on Linux.
Look for updates to come to Google Chrome and Internet Explorer 10 and 11 on Windows 8 and RT to fix these vulnerabilities in their embedded Flash clients.
