Memory leak in Huawei S9300, S5300, S5700, S6700, S7700, S9700, and S12700 devices allows remote attackers to cause a denial of service (memory consumption and restart) via a large number of malformed packets.
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.
