CVE-2016-8786
Huawei S12700 V200R005C00, V200R006C00, V200R007C00, V200R008C00, S5700 V200R006C00, V200R007C00, V200R008C00, S6700 V200R008C00, S7700 V200R001C00, V200R002C00, V200R003C00, V200R005C00, V200R006C00, V200R007C00, V200R008C00, S9700 V200R001C00, V200R002C00, V200R003C00, V200R005C00, V200R006C00, V200R007C00, V200R008C00 have a denial of service (DoS) vulnerability. Due to the lack of input validation, a remote attacker may craft a malformed Resource Reservation Protocol (RSVP) packet and send it to the device, causing a few buffer overflows and occasional device restart.
CVSS
- Versión: 3.0
- Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Debido a la falta de validación de entradas, un atacante remoto podría manipular un paquete RSVP (Resource Reservation Protocol) mal formado y enviarlo al dispositivo, lo que provocaría unos pocos desbordamientos de búfer y reincios ocasionales del dispositivo."
