TITLE

Autonomy KeyView Filter SDK of kvolefio.dll Integer overflow vulnerability

DESCRIPTION

Integer overflow in kvolefio.dll 8.5.0.8339 and 10.5.0.0 in the Autonomy KeyView Filter SDK, as used in IBM Lotus Notes 8.5, Symantec Mail Security for Microsoft Exchange 5.0.10 through 5.0.13, and other products, allows context-dependent attackers to execute arbitrary code via a crafted OLE document that triggers a heap-based buffer overflow. Autonomy KeyView module is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data before copying it to insufficiently sized buffers. Exploiting this issue will allow an attacker to corrupt memory and cause denial-of-service conditions and may potentially allow the execution of arbitrary code in the context of an application using the module. Multiple products using the KeyView module are affected, including: Symantec Mail Security for Domino Symantec Mail Security for Microsoft Exchange Symantec Mail Security for SMTP Symantec Brightmail Gateway Symantec Data Loss Prevention Detection Servers Symantec Data Loss Prevention Endpoint Agents Symantec IM Manager. KeyView is a software package for exporting, converting and viewing files in various formats. For more information: SA38797 SOLUTION: Please see the vendor's advisory for a list of fixes. iDefense Security Advisory 03.04.10 http://labs.idefense.com/intelligence/vulnerabilities/ Mar 04, 2010 I. BACKGROUND Autonomy KeyView SDK is a commercial SDK that provides many file format parsing libraries. It supports a large number of different document formats. KeyView is used by several popular vendors for processing documents. For more information, visit the URLs referenced below. http://www.autonomy.com/ II. This vulnerability occurs when processing specially crafted documents. When processing such a document, the software reads an integer value from the file and uses this integer, without validation, in an arithmetic operation to calculate the amount of memory to allocate. If a sufficiently large number is supplied, the calculation overflows, resulting in a buffer of insufficient size being allocated. The software then proceeds to copy data into this under-sized buffer. This results in an exploitable heap buffer overflow condition. III. ANALYSIS Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the targeted application. In order to exploit this vulnerability, an attacker must cause a specially crafted OLE file to be processed by an application using the Autonomy KeyView SDK. This includes file types such as PowerPoint, Excel, Word, as well as other document formats. The amount of user interaction required is tied to the way in which the KeyView SDK is used. In cases such as Lotus Notes, this requires that an attacker convince a user to view an e-mail attachment; however, in other cases, processing may take place automatically as a document is examined. The privileges that an attacker gains may be different for each application that uses the KeyView SDK. For example, exploiting this issue via Lotus Notes yields the current user's privileges while exploiting the vulnerability via Symantec Mail Security yields SYSTEM privileges. IV. All applications that utilize Autonomy's KeyView SDK to process untrusted content are also believed to be vulnerable. V. WORKAROUND For Symantec Mail Security, disabling "content filtering" will prevent exploitation. Unfortunately, disabling the affected "kvolefio.dll" library causes additional issues. Working around this issue by disabling filters would require all filters that utilize this module to be disabled. It is not clear at this time if this is even possible. iDefense will update this workaround once more information has been received from the vendor(s). VI. VENDOR RESPONSE Symantec Corporation has released a solution which addresses this issue.
