Adobe patches security issues in Flash and Shockwave players

New versions of the players fix critical vulnerabilities in each.

Adobe has released updates for the Flash Player and Shockwave Player to address vulnerabilities in the previous versions. In the case of the Flash vulnerability, Adobe says that there is an exploit available, but not whether it is being used in the wild.


The vulnerabilities in the old Flash Player are both critical and highest priority. The vulnerable versions are:

  • Adobe Flash Player 11.9.900.152 and earlier versions for Windows and Macintosh
  • Adobe Flash Player and earlier versions for Linux
  • Adobe AIR and earlier versions for Windows and Macintosh
  • Adobe AIR and earlier versions for Android
  • Adobe AIR SDK and earlier versions
  • Adobe AIR SDK & Compiler and earlier versions

Flash Player users on Windows and Mac should update to version 11.9.900.170. Flash Player users on Linux should update to version The current version of Google Chrome (31.0.1650.63) already integrates the current version of Flash Player, as does the latest versions of Internet Explorer 10 and 11.

Adobe says that they are "...aware of reports that an exploit designed to trick the user into opening a Microsoft Word document with malicious Flash (.swf) content exists..." Adobe Flash Player has mitigated against this form of attack since version 11.6.
