CVE-2011-0026

Published Jan 12, 2011 microsoft CWE-189

Overview

CVE-2011-0026 is a known-severity vulnerability affecting microsoft data_access_components. It was published on January 12, 2011.

Technical Description

Integer signedness error in the SQLConnectW function in an ODBC API (odbc32.dll) in Microsoft Data Access Components (MDAC) 2.8 SP1 and SP2, and Windows Data Access Components (WDAC) 6.0, allows remote attackers to execute arbitrary code via a long string in the Data Source Name (DSN) and a crafted szDSN argument, which bypasses a signed comparison and leads to a buffer overflow, aka "DSN Overflow Vulnerability."

Remediation

Check the references section for vendor advisories and patches from microsoft. Update data_access_components to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
