Debian Security Advisory DSA 492-1 security@debian.org

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.
