(RHSA-2003:317) iproute security update

The iproute package contains advanced IP routing and network device
configuration tools.

Herbert Xu reported that iproute can accept spoofed messages sent on the
kernel netlink interface by other users on the local machine. This could
lead to a local denial of service attack. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2003-0856 to
this issue.

Users of iproute should upgrade to these erratum packages, which contain a
patch that checks that netlink messages actually came from the kernel.
