Microsoft Windows BR549.DLL ActiveX control contains vulnerability

Overview

The Microsoft Windows BR549.DLL ActiveX control, which provides support for the Windows Reporting Tool, contains an unknown vulnerability. The impact of this vulnerability is not known.

Description

Microsoft Security Bulletin MS03-032 briefly describes a vulnerability in the BR549.DLL ActiveX control:

This patch also sets the Kill Bit on the BR549.DLL ActiveX control. This control implemented support for the Windows Reporting Tool, which is no longer supported by Internet Explorer. The control has been found to contain a security vulnerability. To protect customers who have this control installed, the patch prevents the control from running or from being reintroduced onto users’ systems by setting the Kill Bit for this control.
The vulnerability may be a buffer overflow. Presumably, the ActiveX control could be instantiated by Internet Explorer (IE) and the vulnerability could be exploited when a victim viewed a specially crafted HTML document such as a web page or HTML email message.

The class ID (CLSID) for this ActiveX control is 167701E3-FDCF-11D0-A48E-006097C549FF.

Impact

The impact of this vulnerability is not known. In the case of a buffer overflow, a remote attacker could execute arbitrary code with the privileges of the user running IE. The attacker could also cause a denial of service.
