Descriptions

The Netskope client service, v57 before 57.2.0.219 and v60 before 60.2.0.214, running with NT\SYSTEM privilege, accepts network connections from localhost. The connection handling function in this service suffers from a stack based buffer overflow in "doHandshakefromServer" function. Local users can use this vulnerability to trigger a crash of the service and potentially cause additional impact on the system.

El servicio cliente Netskope, v57 versiones anteriores a 57.2.0.219 y v60 versiones anteriores a 60.2.0.214, ejecutado con privilegio NT\SYSTEM, acepta conexiones de red de localhost. La función de manejo de conexión en este servicio sufre de un desbordamiento de búfer en la región heap de la memoria en la función "doHandshakefromServer". Los usuarios locales pueden usar esta vulnerabilidad para desencadenar un bloqueo del servicio y causar potencialmente un impacto adicional en el sistema.
