TITLE:
Facebook Photo Uploader ActiveX Control Property Handling Buffer
Overflow

SECUNIA ADVISORY ID:
SA28713

VERIFY ADVISORY:
http://secunia.com/advisories/28713/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Facebook Photo Uploader 4.x
http://secunia.com/product/17433/

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.

SOLUTION:
Update to version 4.5.57.1.

PROVIDED AND/OR DISCOVERED BY:
