Facebook Photo Uploader 4 'ImageUploader4.1.ocx' ActiveX Control Buffer Overflow Vulnerability

Facebook Photo Uploader ActiveX control is prone to a buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied data.

Successfully exploiting this issue may allow remote attackers to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Failed exploit attempts will result in denial-of-service conditions.

The Symantec DeepSight team has confirmed that this issue leads to a crash in 'ImageUploader4.1.ocx' 4.5.57.0; other versions may also be vulnerable. We will update this BID as more information emerges.
