Summary

Critical vulnerabilities have been identified in Illustrator CS3 that could allow an attacker who successfully exploits these potential vulnerabilities to take control of the affected system. A malicious BMP, DIB, RLE, or PNG must be opened in Illustrator by the user for an attacker to exploit these potential vulnerabilities.

Details

Multiple input validation errors have been identified in Illustrator CS3 which could lead to the potential execution of arbitrary code. These vulnerabilities are not remotely exploitable, but could, for instance, be triggered by opening a malicious BMP, DIB, RLE or PNG file delivered to a user via their e-mail client. This is related to a previously released bulletin for Adobe Photoshop, APSB07-13. Users are recommended to update their installations with the instructions above, and Adobe encourages all customers to be cautious before opening any unknown file, regardless of which application they may be using.
