Multiple vendor IPv6 NDP implementation denial of service

multiple-vendor-ndp-dos (45601) The risk level is classified as MediumMedium Risk

Description:

Multiple vendor IPv6 Neighbor Discovery Protocol (NDP) implementations are vulnerable to a denial of service, caused by a failure to validate the origin of Neighbor Discovery messages. By sending a spoofed neighbor solicitation request, a remote attacker with IPv6 connectivity to the targeted system could exploit this vulnerability to intercept traffic or add a false entry to the router's neighbor cache, which could result in a denial of service.

*CVSS:

Denial of Service

Remedy:

For FreeBSD:
Refer to FreeBSD-SA-08:10.nd6 for patch, upgrade or suggested workaround information. See References.

For FTOS:
Upgrade to the latest version of FTOS (E7.7.1.1 or later), available from the Force10 Networks Web site. See References.

For other distributions:
Apply the appropriate update for your system. See References.
