The IP stack in multiple Huawei Campus series switch models allows remote attackers to cause a denial of service (reboot) via a crafted ICMP request message.
Huawei S12700 switches with software before V200R008C00SPC500 and S5700 switches with software before V200R005SPH010, when the debug switch is enabled, allows remote attackers to cause a denial of service or execute arbitrary code via crafted DNS packets.
