Detail

Two vulnerabilities were discovered in zebra, an IP routing daemon:

CAN-2003-0795 - a bug in the telnet CLI could allow a remote attacker to cause a zebra process to crash, resulting in a denial of service.

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.
