Two security patches were released yesterday by Adobe for their two popular graphics applications.

Adobe states:

The identified vulnerability allows non-privileged users permission to change key program files. This condition presents a risk for shared, multi-user systems. On such systems, a hostile user could take advantage of this condition to replace these program files with malicious or harmful code that could read, write, or destroy sensitive data if subsequently run by a privileged user.

Both patches can be found here:

According to the patch log, it appears that there is just 1 file you need to download which will patch both programs.
