Huawei AR1220 routers with software before V200R005SPH006 allow remote attackers to cause a denial of service (board reset) via vectors involving a large amount of traffic from the GE port to the FE port.

There is a digital signature verification bypass vulnerability in AR1200, AR1200-S, AR150, AR160, AR200, AR2200, AR2200-S, AR3200, SRG1300, SRG2300 and SRG3300 Huawei routers. The vulnerability is due to the affected software improperly verifying digital signatures for the software image in the affected device. A local attacker with high privilege may exploit the vulnerability to bypass integrity checks for software images and install a malicious software image on the affected device.
