CAN-2003-0858 - netlink messages sent by other users (rather than the kernel) would be accepted, leading to a denial of service. For the current stable distribution (woody) this problem has been fixed in version 0.92a-5woody2. The zebra package has been obsoleted in the unstable distribution by GNU Quagga, where this problem was fixed in version 0.96.4x-4. We recommend that you update your zebra package.
