Descriptions
A vulnerability in the Layer 2 Ethernet services of Cisco IOS XR Software could allow an unauthenticated, adjacent attacker to cause the line card network processor to reset, resulting in a denial of service (DoS) condition.
This vulnerability is due to the incorrect handling of specific Ethernet frames that are received on line cards that have the Layer 2 services feature enabled. An attacker could exploit this vulnerability by sending specific Ethernet frames through an affected device. A successful exploit could allow the attacker to cause the ingress interface network processor to reset, resulting in a loss of traffic over the interfaces that are supported by the network processor. Multiple resets of the network processor would cause the line card to reset, resulting in a DoS condition.
Una vulnerabilidad en los servicios Ethernet de capa 2 del software Cisco IOS XR podría permitir que un atacante adyacente no autenticado provoque que el procesador de red de la tarjeta de línea se reinicie, lo que resultaría en una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe al manejo incorrecto de tramas Ethernet específicas que se reciben en tarjetas de línea que tienen habilitada la función de servicios de Capa 2. Un atacante podría aprovechar esta vulnerabilidad enviando tramas Ethernet específicas a través de un dispositivo afectado. Un exploit exitoso podría permitir al atacante hacer que el procesador de red de la interfaz de entrada se reinicie, lo que resultaría en una pérdida de tráfico en las interfaces admitidas por el procesador de red. Múltiples reinicios del procesador de red provocarían que la tarjeta de línea se reinicie, lo que resultaría en una condición DoS.
