Description |
|
|
Se ha descubierto una vulnerabilidad en Microsoft Data Access Components (MDAC) 2.5 SP3, 2.7 SP1, 2.8, y en 2.8 SP1. La vulnerabilidad reside en un error en el método "Execute()" en ADODB.Connection 2.7 y en 2.8 en el control de objetos ActiveX (ADODB.Connection.2.7 y ADODB.Connection.2.8) debido a que no maneja correctamente la memoria cuando el segundo argumente es un BSTR. Un atacante remoto podría causar una denegación de servicio y posiblemente ejecutar código arbitrario mediante ciertas cadenas de caracteres en el segundo y tercer argumento. Existe un exploit público disponible. |
