Oracle JInitiator ActiveX control stack buffer overflows

Vulnerability Note VU#474433

Original Release Date: 2007-08-28 | Last Revised: 2009-04-13

Overview

The Oracle JInitiator ActiveX control contains multiple stack buffer overflows, which could allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

Oracle JInitiator allows users to run Oracle Developer Server applications within a web browser. Oracle JInitiator includes an ActiveX control called beans.ocx. The Oracle JInitiator ActiveX control is vulnerable to multiple stack buffer overflows in initialization parameters.

This vulnerability appears to be present in versions 1.1.8.x through 1.1.8.26 of the Oracle JInitiator software. In our testing, the 1.3.1.x versions of JInitiator do not contain these buffer overflows. However, installing a later version of the software will not remove the vulnerable version of the control.

Impact

A remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system with privileges of the user.

Solution

Apply an update
Oracle reports that this issue is resolved in the Oracle Critical Patch Update for January 2008. According to the Oracle blog, the update is also available in Patch 6612584.
