TITLE:
Cisco IOS IPv6 Routing Header Information Disclosure and Denial of
Service

SECUNIA ADVISORY ID:
SA26359

VERIFY ADVISORY:
http://secunia.com/advisories/26359/

CRITICAL:
Moderately critical

IMPACT:
Exposure of sensitive information, DoS

WHERE:
>From remote

OPERATING SYSTEM:
Cisco IOS XR 3.x
http://secunia.com/product/4907/
Cisco IOS R12.x
http://secunia.com/product/50/
Cisco IOS 12.x
http://secunia.com/product/182/

DESCRIPTION:
A vulnerability has been reported in Cisco IOS and IOS XR, which can
be exploited by malicious people to potentially disclose sensitive
information or to cause a DoS (Denial of Service).

The vulnerability is caused due to an error when processing IPv6
packets with a Type 0 routing header. This can lead to disclosure of
16 bytes of packet buffer memory in the destination IPv6 address in a
IPv6 packet header, and can also be exploited to crash an IOS device
or the IPv6 subsystem on devices running Cisco IOS XR by sending a
specially crafted IPv6 packet.

Successful exploitation requires that the device is configured to use
IPv6.

The following products are reportedly not affected:
* Cisco PIX and ASA Appliances
* Cisco Firewall Services Module (FWSM)
* Cisco MDS

SOLUTION:
Apply updated versions. See vendor advisory for more details.

Filter packets that contain Type 0 routing headers. See Workarounds
section in vendor advisory.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor, who also credits Tom Cross, IBM ISS X-Force.
