Hello, Last November a bug was found in iproute. CAN-2003-0856 has more information. Basically, netlink packets can come from any user. If a program performs action based on netlink packets, they must be examined to make sure they came from the place they are expected (the kernel). Attached is a patch against pre8. Please apply this before releasing 1.00 final. All users of busy box may be vulnerable to local attacks without it. Best Regards, Steve Grubb
