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 S5300 Campus Series switches with software before V200R005SPH008 do not mask the password when uploading files, which allows physically proximate attackers to obtain sensitive password information by reading the display.
