Debian DSA-415-1 : zebra - denial of service

medium Nessus Plugin ID 15252

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

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.
