Cisco Security Advisory: IPv6 Crafted Packet Vulnerability

by Cisco Systems Product Security Incident Response Team

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: IPv6 Crafted Packet Vulnerability Revision 1.0 For Public Release 2005 July 29 0800 UTC - ------------------------------------------------------------------------------- Contents ======== Summary Affected Products Details Impact Software Versions and Fixes Obtaining Fixed Software Workarounds Exploitation and Public Announcements Status of This Notice: INTERIM Distribution Revision History Cisco Security Procedures - -------------------------------------------------------------------------- Summary ======= Cisco Internetwork Operating System (IOS ) Software is vulnerable to a Denial of Service (DoS) and potentially an arbitrary code execution attack from a specifically crafted IPv6 packet. The packet must be sent from a local network segment. Only devices that have been explicitly configured to process IPv6 traffic are affected. Upon successful exploitation, the device may reload or be open to further exploitation. Cisco has made free software available to address this vulnerability for all affected customers. This advisory will be posted at http://www.cisco.com/warp/public/707/cisco-sa-20050729-ipv6.shtml. Affected Products ================= Vulnerable Products This issue affects all Cisco devices running any unfixed version of Cisco IOS code that supports, and is configured for, IPv6. A device which supports IPv6 must have the interfaces specifically disabled to not be affected. IPv6 must be completely disabled using both the command no ipv6 address and no ipv6 enable on each interface. Sample output of the show ipv6 interface command is shown below for two systems, one not configured for IPv6 and one configured for IPv6. An empty output or an error message will be displayed if IPv6 is disabled or unsupported on the system. Router#show ipv6 int fa 0/0 -here you see blank output In the example below the system is vulnerable. Router#show ipv6 interface Serial1/0 is up, line protocol is up IPv6 is enabled, link-local address is FE80::A8BB:CCFF:FE00:D200 Global unicast address(es): 2001:1:33::3, subnet is 2001:1:33::/64 Joined group address(es): FF02::1 FF02::1:FF00:3 FF02::1:FF00:D200 MTU is 1500 bytes ICMP error messages limited to one every 100 milliseconds ICMP redirects are enabled ND DAD is enabled, number of DAD attempts: 1 ND reachable time is 30000 milliseconds Router# A router that has IPv6 enabled on a physical or logical interface is vulnerable to this issue even if ipv6 unicast-routing is globally disabled. The show ipv6 interface command can be used to determine whether IPv6 is enabled on any interface. To determine the software running on a Cisco product, log in to the device and issue the show version command to display the system banner. Cisco IOS Software will identify itself as "Internetwork Operating System Software" or simply "IOS." On the next line of output, the image name will be displayed between parentheses, followed by "Version" and the IOS release name. Other Cisco devices will not have the show version command or will give different output. The following example shows a product running IOS release 12.3(6) with an image name of C2600-JS-MZ: Cisco Internetwork Operating System Software IOS (tm) C2600 Software (C2600-JS-MZ), Version 12.3(6), RELEASE SOFTWARE (fc1) Additional information about Cisco IOS release naming can be found at http:// www.cisco.com/warp/public/620/1.html. Products Confirmed Not Vulnerable Products that are not running Cisco IOS are not affected. Products running any version of Cisco IOS that do not have IPv6 configured interfaces are not vulnerable. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= IPv6 is the "Internet Protocol Version 6", designed by the Internet Engineering Task Force (IETF) to replace the current version Internet Protocol, IP Version 4 (IPv4). A vulnerability exists in the processing of IPv6 packets. Crafted packets from the local segment received on logical interfaces (that is, tunnels including 6to4 tunnels) as well as physical interfaces can trigger this vulnerability. Crafted packets can not traverse a 6to4 tunnel and attack a box across the tunnel. The crafted packet must be sent from a local network segment to trigger the attack. This vulnerability can not be exploited one or more hops from the IOS device. This issue is documented in Cisco bug ID CSCef68324. Impact ====== Successful exploitation of the vulnerability may result in a reload of the device or execution of arbitrary code. Repeated exploitation could result in a sustained DoS attack or execution of arbitrary code. Software Versions and Fixes =========================== Each row of the Cisco IOS software table below describes a release train and the platforms or products for which it is intended. If a given release train is vulnerable, then the earliest possible releases that contain the fix (the First Fixed Release) and the anticipated date of availability for each are listed in the Rebuild and Maintenance columns. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. The release should be upgraded at least to the indicated release or a later version (greater than or equal to the First Fixed Release label). +---------------------------------------------+ | Major Release | Availability of Repaired | | | Releases | |----------------+----------------------------| | Affected | | | | 12.0-Based | Rebuild | Maintenance | | Release | | | |----------------+--------------+-------------| | 12.0S | 12.0(26)S6 | | |----------------+--------------+-------------| | | 12.0(27)S5 | | |----------------+--------------+-------------| | | 12.0(28)S3 | | |----------------+--------------+-------------| | | 12.0(30)S2 | 12.0(31)S | |----------------+----------------------------| | 12.0SX | Vulnerable;

In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center ("TAC") for assistance. Obtaining Fixed Software ======================== Customers with Service Contracts Customers with contracts should obtain upgraded software through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's worldwide website at http:// www.cisco.com. Customers using Third-party Support Organizations Customers whose Cisco products are provided or maintained through prior or existing agreement with third-party support organizations such as Cisco Partners, authorized resellers, or service providers should contact that support organization for assistance with the upgrade, which should be free of charge. Customers without Service Contracts Customers who purchase direct from Cisco but who do not hold a Cisco service contract and customers who purchase through third-party vendors but are unsuccessful at obtaining fixed software through their point of sale should get their upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows. * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac(a)cisco.com Please have your product serial number available and give the URL of this notice as evidence of your entitlement to a free upgrade. Free upgrades for non-contract customers must be requested through the TAC. Please do not contact either "psirt(a)cisco.com" or "security-alert(a)cisco.com" for software upgrades. See http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml for additional TAC contact information, including special localized telephone numbers and instructions and e-mail addresses for use in various languages. Customers may only install and expect support for the feature sets they have purchased. By installing, downloading, accessing or otherwise using such software upgrades, customers agree to be bound by the terms of Cisco's software license terms found at http://www.cisco.com/public/sw-license-agreement.html, or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public /sw-center/sw-usingswc.shtml. Workarounds =========== The effectiveness of any workaround is dependent on specific customer situations such as product mix, network topology, traffic behavior, and organizational mission. Due to the variety of affected products and releases, customers should consult with their service provider or support organization to ensure any applied workaround is the most appropriate for use in the intended network before it is deployed. In networks where IPv6 is not needed, disabling IPv6 processing on an IOS device will eliminate exposure to this vulnerability. On a router which supports IPv6, this must be done by issuing the command "no ipv6 enable" and "no ipv6 address" on each interface. Exploitation and Public Announcements ===================================== This vulnerability was disclosed on July 27, 2005 at the Black Hat security conference. Status of This Notice: INTERIM ============================== THIS ADVISORY IS PROVIDED ON AN "AS IS" BASIS AND DOES NOT IMPLY ANY KIND OF GUARANTEE OR WARRANTY, INCLUDING THE WARRANTY OF MERCHANTABILITY.

FYI. Apologies for duplicate copies. philip -- Asia Pacific Regional Internet Conference on Operational Technologies Perth, Western Australia 22nd Feb - 3rd March 2006 The APRICOT 2006 Program Committee is now seeking contributors to the program. This is the main call for Presentations & Tutorials before the final program is fixed. We would like to give people the opportunity to submit their proposals early and to encourage people in the Asia Pacific region who have not previously presented their work to do so. We are looking for people who would like to: * Offer a technical tutorial on an appropriate topic; and/or * Participate in the technical conference sessions as a speaker; and/or * Convene and chair a Birds of a Feather (BOF) session. CONFERENCE MILESTONES: 20 November 2005: Receive all Speaker & Instructor submissions 5 December 2005: Announce Selected Speakers and Tutorials 1 February 2006: All Presentation Materials are received from Speakers & Instructors 22 February to 26 February 2006: Pre-conference Workshops 27 February to 28 February 2006: Tutorials 01 March to 02 March 2006: Conference 03 March 2006: APNIC Meeting PROGRAM MATERIAL ---------------- TUTORIALS: Tutorials are full-day workshops which focus on a particular subject in-depth. They may be presented by a single Instructor, or a team of instructors working together. Tutorial Instructors are encouraged to also sign up to be a Speaker in the Technical Conference Program as well. You can sign up to give a tutorial and/or conference session presentation by following the instructions at the end of this message for signing up as a speaker or instructor. Tutorial topics that have been successful in the past, or which have been requested for this year, include: * Network security, IPSec, Auditing/Forensics, DDoS Mitigation, VoIP Security * Address planning, conservation, responsibility and migration to IPv6 * High performance IP backbone routing and management * BGP MultiHoming * MPLS * Network planning, management and traffic engineering * Operation experiences and issues in deploying Internet Infrastructure * Internet exchanges, construction, peering and collocation * Operations, NOC, Helpdesk and other support aspects * BIND, DNSSEC, Split Horizon DNS, and Reverse and multilingual DNS * Broadband first/last mile access technologies * Mobile and wireless technologies * Content, Applications, streaming and multimedia infrastructure * VoIP, Unified messaging, scaling e-mail infrastructure, Asterisk, etc. * Hosted Essential Services (mail, DNS, etc), Server scaling, Open source * Training the Trainers Workshops / Educators Track * Quantitative Analysis for Internet Public Policy The program committee will consider proposals for tutorials in any of these areas, and also in new areas. There will be two days of Tutorials. Tutorials last 1/2 day or a full day. If you have an idea for a tutorial subject that is not listed, please feel free to submit it to us. TECHNICAL CONFERENCE SESSIONS: The Main Conference Program for 2006 will be made up of 2 days with 3 tracks each day (Plus the APNIC and other concurrent AP* org Tracks which is managed by various AP* groups independent of APRICOT). Each Track has three 1.5 hour sessions on Wednesday and four 1.5 hour sessions on Thursday. Each session can have 3 - 4 presentations (therefore allowing 20-30 minutes per speaker) or a panel. Sessions are chaired by persons of appropriate expertise in the subject matter of the session, and will include ample time for questions from the audience. If you would like to give a presentation at one or more of the sessions, follow the instructions at the end of this message for signing up as a speaker or instructor.

When considering a presentation or tutorial, remember that the APRICOT audience is mainly comprised of technical network operators and engineers with a wide range of experience levels from beginners to multi-year experience. There is a strong orientation to offer core skills and basic knowledge in the tutorials and to address issues relevant to the day-to-day operations of ISPs over the next 12 - 18 months in the conference sessions. IMPORTANT NOTE: ---------------- APRICOT is a TECHNICAL conference and marketing and commercial content is not allowed within the program. The program committee is charged with maintaining the technical standard of APRICOT, and will therefore not accept inappropriate materials. It is expected that the presenter be a technical person and not a sales or marketing person. The audience is extremely technical and expects that the speakers are themselves very knowledgeable. All sessions provide time for questions, so presenters should expect technical questions, and be prepared to deliver insightful and technically deep responses. FUNDING AND SUPPORT Since APRICOT is a not-for-profit event that tries to keep the cost to attendees low, we do not have too much money to pay the costs of speakers. If you belong to a company or organization that can cover you travel expenses, that is a big help. Only in exceptional circumstances of hardship will APRICOT be able to consider assisting with travel expenses of tutorial instructors. Of course, Tutorial Instructors will not have to pay any registration fee to attend the conference or tutorials. And Conference Speakers do not have to pay for registration to the Technical Conference. SIGNING UP AS A SPEAKER, INSTRUCTOR OR BOF Convener If you would like to be considered as a tutorial instructor, session speaker, or a convener of a BOF, please fill in the form at http://www.apricot2006.net/index.php/fuseaction/home.callforpapers More information on the conference is available at http:/www.apricot2006.net IF YOU WOULD LIKE TO BE REMOVED FROM MAILING LIST: send an email to remove(a)ibd.com Thanks and if you have any questions, please contact myself & Tom Vest (email is best).
