Just saw this over on HardOCP and thought I would post it along. here is the dish from Adobe's site:

Overview: Adobe has been made aware that the file and folder permissions for Photoshop CS2, Illustrator CS2, and Adobe Help Center can permit non-privileged users to change key program files. This condition presents a risk for shared, multi-user systems. Adobe is providing update utilities which correct these access permission issues and prevent manipulation of the program files by non-privileged users. Adobe recommends that customers using CS2 products on shared systems apply these updates.
Effect: If exploited, this vulnerability could allow a hostile user 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.
