Vulnerability Note VU#776931
Aurigma ImageUploader ActiveX control stack buffer overflows
Overview
The Aurigma ImageUploader ActiveX control contains multiple stack
buffer overflow vulnerabilities, which may allow a remote attacker to
execute arbitrary code on a vulnerable system.
I. Description
Aurigma ImageUploader is an ActiveX control that provides the ability
to upload pictures using the Internet Explorer web browser. The
Aurigma ImageUploader ActiveX control is used by multiple web sites,
such as Facebook and MySpace. This ActiveX control contains multiple
stack buffer overflows in several properties, including Action,
ExtractExif, and ExtractIptc. Limited testing has shown that versions
up to and including version 5.0.30 may be vulnerable.
Exploit code is publicly available.
II. Impact
By convincing a user to view a specially crafted HTML document (e.g.,
a web page or an HTML email message or attachment), a remote,
unauthenticated attacker may be able to execute arbitrary code with
the privileges of the user on a vulnerable system.
III. Solution
We are currently unaware of a practical solution to this problem.
Please consider the following workarounds:
Disable the Aurigma ImageUploader ActiveX controls in Internet
Explorer
