Description

Who: FaceBook http://www.facebook.com

Aurigma http://www.aurigma.com

What: FaceBook uses Aurigma's ImageUploader control. This control enables users to upload photos to FaceBook.

How: Please note that this vulnerability is DIFFERENT than the one that I previously posted. This also affects the stock Aurigma ImageUploader control.

The control is vulnerable to a stack-based buffer overflow in the ExtractExif and ExtractIptc properties. See the exploit code for buffer offsets. Other properties may be vulnerable as well to a DoS and/or code execution.

The following controls are vulnerable, other version may be vulnerable as well:

{5C6698D9-7BE4-4122-8EC5-291D84DBD4A0} FaceBook PhotoUploader 4.5.57.0

{6E5E167B-1566-4316-B27F-0DDAB3484CF7} Aurigma ImageUploader4 4.6.17.0 Aurigma ImageUploader4 4.5.70.0 Aurigma ImageUploader4 4.5.126.0

{BA162249-F2C5-4851-8ADC-FC58CB424243} Aurigma ImageUploader5 5.0.10.0

The following controls are NOT vulnerable:

{5C6698D9-7BE4-4122-8EC5-291D84DBD4A0} FaceBook PhotoUploader 4.5.57.1

Fix: FaceBook PhotoUploader: Update to 4.5.57.1 Aurigma: No official fix known. Vendor has been notified

Workaround: Set the killbit for these controls, see http://support.microsoft.com/kb/240797

Exploit: Code should be posted on milw0rm shortly
