Yamaha RTX, RT, SRT, RTV, RTW, and RTA series routers with firmware 6.x through 10.x, and NEC IP38X series routers with firmware 6.x through 10.x, do not properly handle IP header options, which allows remote attackers to cause a denial of service (device reboot) via a crafted option that triggers access to an invalid memory location.

Cross-site request forgery (CSRF) vulnerability in the management interface in multiple Yamaha RT series routers allows remote attackers to change password settings and probably other configuration settings as administrators via unspecified vectors.
