Package        : iproute
Vulnerability  : denial of service
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2003-0856
Debian Bug     : 242994

Herbert Xu reported that local users could cause a denial of service
against iproute, a set of tools for controlling networking in Linux
kernels.  iproute uses the netlink interface to communicate with the
kernel, but failed to verify that the messages it received came from
the kernel (rather than from other user processes).

For the current stable distribution (woody) this problem has been
fixed in version 20010824-8woody1.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you update your iproute package.

Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
