Multiple heap-based buffer overflows in the eSap software platform in Huawei Campus S9300, S7700, S9700, S5300, S5700, S6300, and S6700 series switches; AR150, AR160, AR200, AR1200, AR2200, AR3200, AR530, NetEngine16EX, SRG1300, SRG2300, and SRG3300 series routers; and WLAN AC6005, AC6605, and ACU2 access controllers allow remote attackers to cause a denial of service (device restart) via a crafted length field in a packet.

Huawei S5700 and S6700 with software of V200R005C00 have a DoS vulnerability due to insufficient validation of the Network Quality Analysis (NQA) packets. A remote attacker could exploit this vulnerability by sending malformed NQA packets to the target device. Successful exploitation could make the device restart.
