Detail

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."

Microsoft Data Access Components and Windows Data Access Components are prone to an overflow condition. The 'SQLConnectW' function fails to properly sanitize user-supplied input resulting in a buffer overflow. With a specially crafted long string in the Data Source Name and a crafted szDSN argument, a remote attacker can potentially execute arbitrary code.
