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

The following controls are NOT vulnerable:
{5C6698D9-7BE4-4122-8EC5-291D84DBD4A0}
FaceBook PhotoUploader 4.5.57.1
Fix:
