Web and print publishing software maker Adobe Systems has pushed out security patches to cover a potentially serious code execution flaw in the Adobe Creative Suite 2 platform.

The flaw, which carries an "important" rating, affects Adobe Creative Suite 2, Adobe Photoshop CS2 and Adobe Illustrator CS2 on both Windows and Mac OS platforms.

San Jose, Calif.-based Adobe is working on a plan release security updates on a monthly cycle, but a spokesman told eWEEK that this batch of patches is not part of the scheduled updates that will be implemented later this year.

According to a security bulletin from Adobe, the vulnerability could be exploited by malicious hackers launch security bypass, data manipulation and privilege escalation attacks.

"If exploited, this vulnerability could allow a hostile user to replace program files with malicious or harmful code that could read, write, or destroy sensitive data if subsequently run by a privileged user," Adobe warned.

The flaw is caused due to insecure default file permissions being set on the installed files and folders.

This allows any non-privileged users on the system to remove the files or replace them with malicious binaries.

Adobe said the vulnerability presents a risk for shared, multi-user systems.

On such systems, the company said a hostile user could replace program files with dangerous code that would execute when subsequently run by a privileged user.

The company warned that the malicious code could be used to read, write or completely destroy sensitive corporate data.

Adobe credited security researchers Sudhakar Govindavajhala and Andrew Appel of Princeton University for reporting the flaw.
