S3300 V100R006C05 have an Ethernet in the First Mile (EFM) flapping vulnerability due to the lack of type-length-value (TLV) consistency check. An attacker may craft malformed packets and send them to a device to cause EFM flapping. S3300 V100R006C05 tiene una vulnerabilidad de oscilación de Ethernet in the First Mile (EFM) debido a la falta de comprobación de consistencia de tiempo-longitud-valor (TLV). Un atacante podría manipular paquetes mal formados y enviarlos a un dispositivo para provocar la oscilación EFM. • http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20170118-01-vrp-en http://www.securityfocus.com/bid/95662 • CWE-417: Communication Channel Errors •

Huawei S9300 with software before V100R006SPH013 and S2300,S3300,S5300,S6300 with software before V100R006SPH010 support Y.1731 and therefore have the Y.1731 vulnerability in processing special packets. The vulnerability causes the restart of switches. Huawei S9300 con software en versiones anteriores a V100R006SPH013 y S2300,S3300,S5300,S6300 con software en versiones anteriores a V100R006SPH010 soporte Y.1731 y por lo tanto tener la vulnerabilidad Y.1731 en el procesamiento de paquetes especiales. Ta vulnerabilidad provoca el reinicio de los switches. • http://www.huawei.com/en/psirt/security-advisories/hw-329625 • CWE-19: Data Processing Errors •
