Overview

IPv6 Type 0 Route Headers allow the sender to control packet routing. This vulnerability may allow an attacker to cause a denial-of-service condition.

Description

Routing header options provided by IPv6 allow packet senders to indicate specific nodes through which the packet should travel. Note that a node is defined as any device that implements IPv6, which includes hosts as well as routing devices. According to FreeBSD-SA-07:03.ipv6:

An attacker can “amplify” a denial of service attack against a link between two vulnerable hosts; that is, by sending a small volume of traffic the attacker can consume a much larger amount of bandwidth between the two vulnerable hosts.
_
An attacker can use vulnerable hosts to “concentrate” a denial of service attack against a victim host or network; that is, a set of packets sent over a period of 30 seconds or more could be constructed such that they all arrive at the victim within a period of 1 second or less._

---

Impact

This condition can facilitate a number of different impacts including packet amplification, bypassing filtering devices, denial of service, and defeating IPv6 Anycast.

Secure Computing Network Security Division __ Affected

Notified: May 09, 2007 Updated: June 15, 2007

Status

Affected

Vendor Statement

Sidewinder G2, Sidewinder 7, and TSP: Not Vulnerable

By default, Sidewinder ignores routing header 0, and strips it from datagrams
passing through the firewall.

TSP drops IPv6 datagrams containing routing headers.

SnapGear: Vulnerable

SnapGear products at version 3.1.5 and earlier honor IPv6 routing header 0.
This will be corrected in an upcoming release.

This vulnerability is not relevant to any other Secure Computing products.

Vendor Information

We are not aware of further vendor information regarding this vulnerability.

Sun Microsystems, Inc. __ Affected

Notified: May 09, 2007 Updated: May 17, 2007

Statement Date: May 16, 2007

Status

Affected

Vendor Statement

Sun can confirm that while Solaris has support for the IPv6 Routing Header type 0 that is described in VU#267289, packets containing this header extension are discarded by default on Solaris 9 and 10, and Solaris 8 can be configured to discard them by setting a kernel driver parameter.

For Solaris systems, this setting is controlled by the ip6_forward_src_routed kernel driver parameter, which defaults to 1 on Solaris 8 systems, and 0 on later systems. The ‘ndd(1M)’ command can be used to set this variable, for example to set it for the current session the command could be used as follows:

ndd -set /dev/ip ip6_forward_src_routed 0
