Adobe is a very large company with lots of products. By being that highly used.
This security issue adresses to almost all versions of Adobe flash player, Adobe reader and Adobe X. This vulnerability can offer full access to your system if it is exploited.
If you are using a Solaris and Linux operating system you should only be worried about the Flash player problem but if you are using Windows or Macintosh you should also be carefull with adobe reader and adobe X as well.
At this point there are already news on an exploit that comes as a .swf file embeded in a .xls file. So if you get any strange emails with this kind of content you should probably pay attention.
