05 Oct '92

============================================================================= CA-92:17 CERT Advisory October 5, 1992 Hewlett-Packard NIS ypbind Vulnerability ----------------------------------------------------------------------------- The CERT Coordination Center has received information concerning a vulnerability in the NIS ypbind module for the Hewlett-Packard (HP) HP/UX Operating System for series 300, 700, and 800 computers. HP is aware of the problem and has produced patches for HP/UX 8.xx versions. This problem is fixed in HP/UX 9.0. Architecture Patch ID Filename Checksum Series 300 PHNE_1359 /hp-ux_patches/s300_400/8.X/PHNE_1359 39206 214 Series 700 PHNE_1360 /hp-ux_patches/s700/8.X/PHNE_1360 37915 299 Series 800 PHNE_1361 /hp-ux_patches/s800/8.X/PHNE_1361 44288 299 The checksums listed above are for the patch archive files from HP. Once unpacked, each shell archive contains additional checksum information in the file "patchfilename.text". This checksum is applicable to the binary patch file "patchfilename.updt". These patches may be obtained from HP via ftp (this is NOT anonymous ftp) or the HP SupportLine. To obtain HP security patches, you must first register with the HP SupportLine. The registration instructions described below will not be included in future advisories. If you have any questions about obtaining or installing the patches, contact the USA HP SupportLine at 415-691-3888, or your local HP SupportLine number. Please note that the telephone numbers in this advisory are appropriate for the USA and Canada. ----------------------------------------------------------------------------- I. Description A vulnerability in HP NIS allows remote NIS servers unauthorized access to local NIS hosts. An HP NIS client will accept ypset requests from hosts outside its NIS domain. II. Impact Root on a remote host running any vendor's implementation of NIS can gain root access on any local host running HP's NIS ypbind. III. Solution All HP NIS clients and servers running ypbind should obtain and install the patch, as detailed below. The two sections below include the instructions for registering with the HP SupportLine and obtaining the HP security patches, and for installing the patch provided by HP. The instructions for installing the patch are also provided in the PHNE_xxxx.text file (this file is created after the patch has been unpacked). ============================================================================ Beginning of Text provided by Hewlett-Packard ============================================================================ HP SupportLine Registration Instructions HP SupportLine phone number: 415-691-3888. There are three categories for obtaining the security patches: 1) Eligible HP SupportLine customers (who have a software support contract or have recently purchased an HP 9000) who access via a terminal or modem. 2) Eligible HP SupportLine customers who would access via Internet. 3) Customers not currently accessing HP SupportLine. For category 1: --------------- Step 1: Dial 415-691-3680. Step 2: When your communications program indicates that you are connected, press "return". The system prompt, ":" or "login:", should appear. Step 3: If your system prompt is ":", log on to the HP SupportLine account by typing "HELLO USER.HPSL", followed by "return". If your system prompt is "login:", log on by typing "login: hpsl", followed by "return". Step 4: When prompted, type your system handle and password, each followed by "return". Both your system handle and password are provided in the cover letter you received with your "Getting Started Kit". Step 5: Press "return" until the HP SupportLine Top Menu screen is displayed. If your terminal does not support block mode, you should enable HPSL's line editor by typing "SET EDITOR LINE" at the command prompt and entering "return". For category 2: --------------- Step 1: HP 9000, HP Apollo, and HP 64000 system users who have been authorized by the National Science Foundation (NSF) to use Internet may access HP SupportLine over the Internet. Connect to HP SupportLine using the address provided in your "Getting Started Kit".

ANS-CIX Interconnection
by Jordan Becker 02 Oct '92

02 Oct '92

Milo asks some good questions that I would like to address, from the perspective of ANS as a general service provider. These comments should not be viewed to represent the interpretation of policy by other organizations. Also, although I think these are important questions to be discussed, I think we are a bit off the topic of T3 network routing plans. > Milo writes: > > One reason why I think some people are very interested in this issue > of default routing to the NSF causing reachibility to CIX connected > facilities is that as I understand it, there is a charge associated > with the CO+RE service, which is supposed to go into some sort of pool > to be distributed in various ways. Now, if a regional doesn't sign > the CO+RE agreement, but because of default routing sends IP packets > to CIX connected sites to their local ENSS, will they be charged for > this in some manner? No, a regional using NSFNET backbone services does not pay ANS anything, nor are they required to make any agreements to do so, even if the packets from a regional using NSFNET services ends up traversing the CIX due to default routing. The regionals pointing default would still be using NSFNET services and are presumed to abide by the NSF AUP. > If not, then why should any regional be a CO+RE > subscriber? Since they mostly point default at the ENSS already, and > then they get connectivity without charge. A regional might choose to become a CO+RE subscriber if they want a commercial restriction free AUP and/or want to use the ANSNET as transit to get the CIX. Costs are recovered from the CO+RE subscriber. This cost recovery is used to defray the costs of the shared ANSNET infrastructure that they use. NSFNET users might get legitimate benefit out of this broadened connectivity, and CO+RE subscribers will be able to access a larger base of connected users. > You see, I think you guys have the greatest reason to not have AS 1957 > routes installed in the routing tables of the various ENSS's whose > members don't subscribe.

And I should point out that if you aren't compensated for > this by the CIX folks (no settlements there) and by the regionals > (because they just point default at you), then NSF would be placed in > the position of supporting non-AUP traffic on resources it pays for. ANS treats AS 1957 as CO+RE subscribers and puts funds in the infrastructure pool on their behalf to cover the compensation for CIX member networks use of ANSNET. There is no cost recovery necessary from regionals that use NSFNET services, even if they talk to CIX networks (via defaults) as long as these regionals are required to abide by the NSF AUP when using NSFNET services. > Of course, > there are limits that you have to deal with if you are using IP > routers as the core of your switching fabric, but I won't go into that > now... :-) Neither will I :-).

To quote an Internet weenie; "you have to do a cost benefit analysis". I am having a hard time following why everyone seems so interested in engineering the ANS network. What problem is being solved? What are you all talking about? peter

ANS to CIX Interconnection

My understanding of the agreement is that it is for the benefit of ANSnet and the CIX, so why should the regionals have to adjust the way they are set up? I'm not just saying this to be contrary (Honest). I am really interested in knowing why this method was chosen. As others have pointed out it move the burden of enforcing policy restriction to individual AS pairs. Comments? I am also interested in hearing what people pointing default at NSFnet plan to do?

Medin" (NASA ARC NSI Office) <medin(a)nsipo.nasa.gov> Ok, I think I'm beginning to understand this better. So, the AS 1957 announcements will not be used as backup for CIX attached AS's to non CO+RE subscribers? It's only for use for the commercial types. One reason why I think some people are very interested in this issue of default routing to the NSF causing reachibility to CIX connected facilities is that as I understand it, there is a charge associated with the CO+RE service, which is supposed to go into some sort of pool to be distributed in various ways. Now, if a regional doesn't sign the CO+RE agreement, but because of default routing sends IP packets to CIX connected sites to their local ENSS, will they be charged for this in some manner? If not, then why should any regional be a CO+RE subscriber? Since they mostly point default at the ENSS already, and then they get connectivity without charge. You see, I think you guys have the greatest reason to not have AS 1957 routes installed in the routing tables of the various ENSS's whose members don't subscribe. Otherwise, those attached AS's could use the CO+RE service, and without an agreement, you could not be compensated for this. And I should point out that if you aren't compensated for this by the CIX folks (no settlements there) and by the regionals (because they just point default at you), then NSF would be placed in the position of supporting non-AUP traffic on resources it pays for. Now, you could legitimately point out that the since the CIX doesn't have a default pointing at the ENSS, that the packets from the non CO+RE subscribing regional would not get back that way, because you would not be sending those CO+RE nets to the CIX. However, I would venture a bet that most of the AS's which attach to the CIX have default pointing at some ENSS, or a router that has total routes from the ENSS. This means that the regional would route to the CIX net via the ANS-CIX interconnect, and then back from the CIX member via their "normal" internet path. So you still get connectivity, albeit with an asymmetric path. This is why some AS who doesn't want CIX connectivity established basically MUST not have a default pointing at an ENSS, but have to recieve total routes (- AS 1957) and run with no default. Because the reverse path will likely still work by following default back to the NSS system. This isn't a problem for us, but might be a problem for others. Now, there are other problems even if you go ahead and not flood AS 1957 routes into the ENSS's that non-CO+RE AS's attach to. For example, if one AS which peers with an ENSS goes the CO+RE route, then the ENSS would have the AS 1957 routes in it's routing table. But since it's the case at several sites that multiple AS's peer with the ENSS, a non CO+RE subscriber AS could point default at the ENSS and gain connectivity with CIX nets because the ENSS had those routes to support the CO+RE subscriber. Things get very complicated here. I presume there is no way you can send a bill to someone you don't have a contract with, so you really need some way of enforcing the charging scheme that's been developed, else you guys will have to result in filtering at the packet forwarding level to prevent that traffic from flowing. Do the NSS routers let you do that? Again, havi ------- End of Forwarded Message

It seems to me that something is missing here. Perhaps I missed it, but I don't think I've seen anything about what CO+RE will be announcing to the CIX. I seem to recall a statement that the CIX does not use default, but that's it. What does ANS CO+RE plan on announcing to the CIX? Ross

ANS-CIX Interconnection

Both ENSSs and CNSSs normally have complete routing information. The ENSSs will selectively announce commercial destination networks only to the participating service providers. It is possible for an ENSS to have partial routing information. However, one problem with this is that multiple regionals peer with the same ENSS at several locations. If an ENSS had partial information to administer some restriction policy, this would affect all regionals that peer with that ENSS. That might adversely affect those regionals that wish to receive the additional routes, and would certainly result in more work to maintain the policy routing database, and routing software, not to mention the management of consensus between each regional that shares an ENSS. There are ways for a regional to block this traffic, even if they continue to use default routes (e.g. create a static route for the commercial destinations to "black hole" the traffic). However it does require some effort by the regional as several people have correctly pointed out. > I can't see the problem you are solving by > engaging in this activity. The basic problem is to give remote CIX members (e.g. some regionals) access to the CIX using the ANSNET as transit. Jordan
