Microsoft Visual Basic Enterprise Edition is vulnerable to a buffer overflow, caused by improper bounds checking by MSDE.dll when handling .dsr files. By persuading a victim to open a specially-crafted .dsr file with an overly long ConnectionName or CommandName string and then opening the Object window and clicking on the ConnectionName or CommandName, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service.
