Adobe Album Starter 3.2 Unchecked Local Buffer Overflow Exploit

Exploitable issue in various Adobe products

Vulnerable applications, tested:
Adobe Photoshop Album Starter
Adobe After Effects CS3
Adobe Photoshop CS3

Not Vulnerable applications, tested:
Adobe Reader
Adobe Flash Player

This bug is related to the parsing of header images, in that the applications do not verify that the image header is valid before trying to render it. This leaves an opportunity to cause an unchecked buffer overflow and allow for the execution of malicious code.

All the issues are standard local overflows whereby an attacker can exploit a machine after sending the malicious image to the user, or by placing the image on a web site or email and waiting for a user to view it in one of the effected products.

One fun thing with Album Starter is that it will run a service which will look for new devices being attached to the system, things like cameras or USB drives and when one is found it will check the device for image files. If some are found, the application will auto-run and import the images and thus allow the attacker to exploit locked workstations.. pretty lame but fun :)
