Description

Overview

Oracle Outside In contains a stack buffer overflow in the CorelDRAW parser, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

Description

Oracle Outside In is a set of libraries that can decode over 500 different file formats. Originally written by Stellent, Outside In is now part of Oracle. The Oracle Outside In libraries are used by a variety of applications, including Oracle Fusion Middleware, Google Search Appliance, Guidance Encase Forensics, AccessData FTK, and Novell Groupwise.

Outside In versions 8.3.5.5927 and 8.3.2.5927 and earlier fail to properly handle CorelDRAW data, which is handled by the imcdr2.flt library.


Impact

By causing an application to process a specially-crafted .CDR file with the Oracle Outside In library, a remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the vulnerable application. Depending on what application is using Outside In, this may happen as the result of some user interaction, such as single-clicking on a file, or it may happen with no user interaction at all.


Solution

Apply an update

These vulnerabilites are addressed in the Oracle Fusion Middleware Critical Patch Update July 2011. Please see Oracle Support Note 1323616.1 (valid Oracle CSI# required) for more details. If you are using an application that uses Outside In, please check with that application's vendor for updates. If updates for your application are not yet available, or if you wish to mitigate other vulnerabilities in Outside In, please consider the following workarounds:


Use the Microsoft Enhanced Mitigation Experience Toolkit

The Microsoft Enhanced Mitigation Experience Toolkit (EMET) can be used to help prevent exploitation of this and other vulnerabilities.

Enable DEP in Microsoft Windows

Consider enabling Data Execution Prevention (DEP) in supported versions of Windows. DEP should not be treated as a complete workaround, but it can mitigate the execution of attacker-supplied code in some cases. Microsoft has published detailed technical information about DEP in Security Research & Defense blog posts "Understanding DEP as a mitigation technology" part 1 and part 2. DEP should be used in conjunction with the application of patches or other mitigations described in this document.

Note that when relying on DEP for exploit mitigation, it is important to use a system that supports Address Space Layout Randomization (ASLR) as well. ASLR is not supported by Windows XP or Windows Server 2003 or earlier. ASLR was introduced with Microsoft Windows Vista and Windows Server 2008. Please see the Microsoft SRD blog entry: On the effectiveness of DEP and ASLR for more details.
