Secunia Advisory SA28713Facebook Photo Uploader ActiveX Control Property Handling Buffer Overflow
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Description
Elazar Broad has discovered a vulnerability in Facebook Photo Uploader, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to a boundary error in the TheFacebook.FacebookPhotoUploader4.4.1 ActiveX control (ImageUploader4.1.ocx) when handling strings assigned to certain properties (e.g. "ExtractExif" and "ExtractIptc"). This can be exploited to cause a stack-based buffer overflow by assigning an overly long string to the affected properties. Successful exploitation allows execution of arbitrary code. The vulnerability is confirmed in version 4.5.57.0. Other versions may also be affected.
