Descriptions

Buffer overflow in the SQLDriverConnect function in unixODBC 2.0.10, 2.3.1, and earlier allows local users to cause a denial of service (crash) via a long string in the FILEDSN option. NOTE: this issue might not be a vulnerability, since the ability to set this option typically implies that the attacker already has legitimate access to cause a DoS or execute code, and therefore the issue would not cross privilege boundaries. There may be limited attack scenarios if isql command-line options are exposed to an attacker, although it seems likely that other, more serious issues would also be exposed, and this issue might not cross privilege boundaries in that context.

** EN DISPUTA ** Desbordamiento de búfer en la función SQLDriverConnect en unixODBC v2.0.10, v2.3.1 y anteriores permite a usuarios locales provocar una denegación de servicio (caída de la aplicación) a través de una cadena larga en la opción FILEDSN. NOTA: este problema puede no ser una vulnerabilidad, ya que la capacidad de establecer esta opción suele implicar que el atacante ya tiene acceso legítimo para causar una denegación de servicio o ejecutar código, y por lo tanto el problema sería de privilegios. Puede haber escenarios limitados de ataque si las opciones de la línea de comandos isql están expuestas a un atacante, aunque parece probable que otros asuntos más graves también se verían expuestos, y este problema podría no cruzar los límites de privilegio en ese contexto.
