Descriptions

A vulnerability in the cryptographic hardware accelerator driver of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a temporary denial of service (DoS) condition. The vulnerability exists because the affected devices have a limited amount of Direct Memory Access (DMA) memory and the affected software improperly handles resources in low-memory conditions. An attacker could exploit this vulnerability by sending a sustained, high rate of malicious traffic to an affected device to exhaust memory on the device. A successful exploit could allow the attacker to exhaust DMA memory on the affected device, which could cause the device to reload and result in a temporary DoS condition.

Una vulnerabilidad en el controlador del acelerador de hardware criptográfico de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software podría permitir que un atacante remoto no autenticado provoque que un dispositivo afectado se recargue, lo que resulta en una denegación de servicio (DoS) temporal. La vulnerabilidad existe debido a que los dispositivos afectados tienen una cantidad limitada de memoria Direct Memory Access (DMA) y el software afectado gestiona incorrectamente los recursos en condiciones de poca memoria. Un atacante podría explotar esta vulnerabilidad enviando continuamente un gran volumen de tráfico a un dispositivo afectado para agotar la memoria del dispositivo. Si se explota con éxito, esta vulnerabilidad podría permitir que el atacante agote la memoria DMA en el dispositivo afectado, lo que podría provocar que el dispositivo se recargue y desemboque en una denegación de servicio (DoS) temporal.
