how to keep nimda and code red from filling apache logs
by Mathias Homann 25 Sep '03

25 Sep '03

Hi all, here's a bit of a step-by-step description on how to keep nimda and codered from filling your apache logs. Parts used: - SuSE 7.2 Professional - SuSEfirewall2 - iptables 1.2.3 - linux kernel 2.4.13-pre5 steps: 1. install kernel sources for a kernel >> 2.4.9, running 2.4.13- pre5 here, works fine so far 2. get the sources for iptables 1.2.3 from http://netfilter.samba.org 3. unpack sources somewhere 4. export KERNEL_DIR=$(where you put the kernel tree) 5. cd into unpacked iptables sources, there's a subdirectory named patch-o-matic there 6. apply wanted patches by running ./runme $(name.of.patch)patch for this here You'll want the string patch You can also apply other patches, like the irc-conntrack patch 7. now there's a little bug in this patch... here's a diff: --- linux/net/ipv4/netfilter/ipt_string.c~ Sun Oct 21 00:16:29 2001 +++ linux/net/ipv4/netfilter/ipt_string.c Sun Oct 21 16:54:45 2001 @@ -62,7 +62,7 @@ sk = skip[haystack[right_end - i]]; sh = shift[i]; - right_end = max(int, right_end - i + sk, right_end + sh); + right_end = max(right_end - i + sk, right_end + sh); } return NULL; 8. now, make config/menuconfig/xconfig... as usual. You can import your running kernel's config first. 9. enable the experimental stuff 10. go to networking options->netfilter, there's an option there to enable string matching; set that to M 11. compile and install kernel as usual; remember to uncomment the export INSTALL_PATH=/boot in the main makefile. 12. now build a rpm file for the new iptables stuff by installing the source rpm which comes with suse, then edit the spec file, put the iptables source in /usr/src/packages/SOURCE and rebuild. 13. now there are some small changes to the firewall config files. a) uncomment the last line in /etc/rc.config.d/firewall2.rc.config: FW_CUSTOMRULES="/etc/rc.config.d/firewall2-custom.rc.config" b) edit that file, I got the following stuff in mine: for forbidden_string in root.exe cmd.exe .ida; do iptables -I input_ext -p tcp --dport http -m string \ --string $forbidden_string -m state \ --state ESTABLISHED -j REJECT --reject-with tcp-reset done put that in the last supfunction defined in the custom rc file. c) change the FW_LOG setting in firewall2.rc.config from reading -log-level warning to -log-level kernel.warning 14. last: some small changes to /sbin/SuSEfirewall2 search in the script for the parts where the modules are loaded and unloaded; be sure to add ipt_string (and the other new modules you created by patching the kernel and enabling them in make config) to the modules loading/unloading code there. 15. reboot 16. if you try now to access (from outside, of course) one of the nimda or codered URLS, all you get is a 'connection reset by peer', and the request doesn't show in apache log files. btw, no guarantees, and the usual YMMV :) bye [L]

suse samba server
by jonathan 23 Jan '03

23 Jan '03

Hello I have basically a suse samba server setup. Eth0 is for the internet connection (cable). Eth1 is my internal network. I use eth1 for my samba server. When i have the shares/ drive letters mapped, whatever, Ill goto access them and that computer will just lockup or timeout for about 1 minute, then it will resume operation normally. I have approx. 5 comptuers on the suse server, and they all do this from windows xp to windows 98se. I am using set up addresses of 192.168.0.x, where is greater than 2. My question is have or is there something Ive setup wrong to cause this pause to occur. ? Its becomming very annoying..and frustrating. Im using kernel 2.4.18-64GB-SMP with a dual processor setup. If anyone has any ideas please let me know. Every package installed is orginal versions from the suse install cdroms. (no updates done). Anything come to mind. btw, ive replaced the switch, with a new netgear one, and all the networks at startech ST100 Realtek 8139 chipsets on 100Tx. Anyone... !

Urgggggg!!! SuSEFirewall2 is getting on my nerves!!!!!
by Chris Bek 08 Jan '03

08 Jan '03

Hi there SuSErs... Well I must be doing something really wrong because everything that I do with SuSEFirewall2 is just not working! I have a small network with 5 PCs (all Win9X) and a Linux box (Currently SuSE 7.3) acting as a server. The server is a DHCP server and a Samba server for the entire network. So far everything is working perfect!!! Users log on the network, logon script executes etc.... Then a new task came up: let's input the internet into the network. Configured a 56Kbps modem on the server with YAST. Manged to get my account setup and running. Made a test connection and netscape works great on the server as well as e-mail (pop3). I tried configuring SuSEfirewall to manage all incoming requests from the PCs of the network. The firewall warned me about masquerading etc. so I downloaded the latest version of SuSEfirewall2 from the internet and installed it. Since I only need direct masquerading to be done (no proxies are currently working on the net) I made all the necessary changes as outlined in the examples supplied with the software. Since I needed to have Samba to keep working on the network, I opened (among others) 139 port for samba to work. Double checked all the changes that I have made and run rcSuSEfirewall2 to see what happens. Strange enough when wvdial executes it tells me that DNS is not functioning properly since www.suse.com cannot be found (or something like that please forgive me I am away from the Linux station now). Further on, when I open mIRC or other like programs (winmx etc) from a station, I look at the activity of IPtraf (I check this to see what happens) and I see no connections being created whatsoever.... mIRC prompts me that there was an error trying to find the host.... I have made no changes to the Win9X PCs. Is there something that I am forgeting to do?? I undestand that it is impossible for all of you to react to this since I have no output of the SuSEfirewall.conf file being published to this message.... I understand. Can someone please send me their configuration file so I can see what you have done, on a system that currently is working fine?? In addition, is there something that I have to do regarding route or routing?? What about the Win9X PCs?? Is there something that I have to do there?? I thank you so very much for all your help is advance!!!! I am killing myself trying to figure this one out for about 2 weeks now and managed nothing more than thin air!!!!! Chris

SSH Authentication
by Joao Reis 18 Nov '02

18 Nov '02

Hi! I implemented a ssh conection from the outside to my intranet. This ssh requires a username and a password. In terms of security what is more secure: require authentication (username and password) or having the public key of each user that connects to our intranet in the authorized public key lists (in this case there is no need for username and password)? In the second case there is no need of authentication and only the users wich have the public keys in the list are allowed to enter in my intranet. This second solution is a good solution or that brings other security problems ? Thanks. -- Farewell. "Keep your friends close, but your enemies closer." "Do or do not.

VPN masquerading
by Joost van der Lugt 06 May '02

06 May '02

Hi all, I am trying to set up VPN masquerading, for a Windows box, and just wondered if there was an easy way to do this, using just the firewall.rc.config script, or do both that plus the custom config script have to be used? I have seen the VPN how-to, however just wondered about a how to aply this with SuSE's scripts. Thanks for any suggestions, (PS if there is someone familiar with setting upo VPN on the SuSe box itself, I would be very interested as well..., of course) - Cheers, Joost

postfix regexp in body_checks
by Philipp Snizek 25 Apr '02

25 Apr '02

Hi, I hope I hit the right list with my request. I'm trying to set up a filter for postfix to filter malicious stuff like all windows executables. For MIME encoded headers I had no problem, this works fine. But if the header is uuencode, the attachment is only visible in the e-mail's body. I tried a regexp like /.*\.(bat|exe|cmd|vbs|vba)/ REJECT in /etc/postfix/body_checks which should filter all *.bat|and so on. But nothing at all happens. Mails go thru as if there wasn't an obstacle. If there is some postfix & regexp pro on this list, please tell me what I am doing wrong. Thanx, Philipp

Ftp & more problems
by Grupo Dignitas 15 Mar '02

15 Mar '02

Friends: The days 5 and 7 of this month, I sent them two mail requesting suggestions about problems that I had (I have) using ftp. Up to now nobody has answered me except for Marc Heuse in private mail. I appeal you since the answer of Marc again (to change the kernel, use at the moment the 2.4.4) he has still left me more doubts. It should have a 'pacific solution' for this problem, that is to say that doesn't commit the costs and working hours of the company. I trust them in that alone precise an orientation, for where to begin to solve the problem, I don't specify magic solutions, these don't exist. The scenario is this: a server Linux with one ADSL 128/256 kb lines in a router Cisco 777, in eth0 it is the net of the company with 45 users using Internet and electronic mail; in eth1 the router mentioned up. The server has the SuSEfirewall2-2.1 and SuSE 7.2, allowing the members of the net to consent to the mentioned services. The company has hired a server ftp (ftp.thecompany.com.ar) with the phone company of our area (Telecom). In the area of systems, two people specify to make ftp to that server and to send for the same way information to the branches that are in other towns; the software that they use in you scheme them client it is the Windows Commander and CuteFTPpro. Now then, either that they use the passive or active mode to make ftp, the server Linux freezes, totally frozen; and it is necessary to restart the server. It doesn't always happen, and it is not known which are the conditions of the server in the moment of the freezing. I cannot have solved the problem for 2 months, I have proven almost everything, from different configurations of the SuSEfirewall2-2.1 until the update of the iptables (1.2.1 at 1.2.2), but anything works. In the inetd.conf has active the Proftpd, although I am not very sure that it is relevant. Now, from D.O.S. in a machine client I use ftp and works well, very well; and Linux doesn't freeze. During the hours of more work, that is to say, all the clients using Internet and mail, it is when more 'hang'; up to four times during the morning. But in the afternoon it diminishes a lot the frequency of the freezing, until any 'hang' in hours of the night. But or less this is what happens, I wait to have explained the problem well. Some help or orientation?. Thanks folks (folks, no list) Ernesto

SuSE Security Announcement: mod_php/mod_php4 (SuSE-SA:2002:007)
by Roman Drahtmueller 13 Mar '02

13 Mar '02

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: mod_php, mod_php4 Announcement-ID: SuSE-SA:2002:007 Date: Thursday, Feb 28th 2002 22:00 MET Affected SuSE products: SuSE Linux 6.4, 7.0, 7.1, 7.2, 7.3, SuSE Linux Connectivity Server, SuSE Linux Enterprise Server 7 Vulnerability Type: remote command execution Severity (1-10): 7 SuSE default package: no Other affected systems: systems running php modules in their webservers Content of this advisory: 1) security vulnerability resolved: mod_php, mod_php4 problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The e-matters team have found multiple remotely exploitable vulnerabilites in the source code responsible for file upload in the apache modules mod_php and mod_php4 (versions 3 and 4). The weakness can be used to have the webserver execute arbitrary code as supplied by the attacker. A temporary workaround against the problem is to disable the file-upload support using the file_uploads directive in the php.ini file. SuSE Linux versions from 6.4 through 7.1 contained mod_php in versions 3, in addition to php4. Starting with SuSE Linux 7.2, all SuSE products do not contain the php-3 package any more. We provide fixed packages for both major versions of mod_php. We recommend to install the upgrade packages as a permanent solution for the problem. SuSE Linux versions 7.1 and 7.2 contained a mod_php4 package for the roxen http server. If you use the roxen webserver, you should use this package. SuSE Linux starting with versions 7.2 have a package called mod_php4-core. This package is required for the update of mod_php4 - by consequence, you can specify both package filenames in the rpm upgrade command after having downloaded the RPM package files. To find out which packages to download and install, use the following command: rpm -qa | grep php Select the packages to download according to the output of the command above and verify their integrity by the methods listed in section 3) of this announcement. Then, install the package(s) using the command "rpm -Fhv file.rpm" to apply the update. To circumvent problems with package versions depending on each other, specify all package filenames that you downloaded on the commandline of the rpm command. Example: "rpm -Fhv f1.rpm f2.rpm". Our maintenance customers are kindly requested to await the arrival of the packages on the maintenance web while these packages are currently going through extensive testing. The packages will be available tomorrow March 1st. Please use the temporary workaround as described above in the meanwhile. SPECIAL INSTALL INSTRUCTIONS: ============================== After applying the update, the apache webserver should be restarted for the update to become effective. To do this, execute the following command as root: rcapache restart i386 Intel Platform: SuSE-7.3 ftp://ftp.suse.com/pub/suse/i386/update/7.3/n1/mod_php4-core-4.0.6-148.i386…

vulnerabilities in SuSE Distributions and Workarounds: - correction: In our last security announcement SuSE-SA:2002:006 (cups), it is advised to restart a running instance of cupsd after performing the rpm update command to make the package upgrade effective (similar to apache in this announcement). The correct command to accomplish a restart of the cups daemon is "rccups restart". - squid (squid2, squid23, squid-beta packages) Malformed ftp:// style URLs are not treated safely in all squid packages. Our packages are available for most architectures and distributions from our ftp server at the usual location, but the security announcement is waiting for the last packages to complete building and testing. - ucdsnmpd The UCD snmpd contains a variety of security related bugs. The SuSE Security Team have been reviewing the code and the available fixes to ensure that all problems get fixed. The update packages are available at the usual location, but the security announcement is waiting for the last packages to complete building and testing. Regardless of whether you use the fixed or the unfixed packages, it is it is strongly recommended to filter SNMP (TCP and UDP packets with destination to port 161) traffic on your inbound router(s). - ssh/openssh Rumours are spreading that there is a new security breach in implementations of secure shell (ssh). The two implementations shipped with SuSE products have been fixed to our best knowlege, and we are not aware of any security holes in these packages. SuSE Security are investigating this issue and will report any vulnerability found through our announcement list suse-security-announce(a)suse.com (subscription information in section 3 of this security announcement). ______________________________________________________________________________ 3) standard appendix: authenticity verification, additional information - Package authenticity verification: SuSE update packages are available on many mirror ftp servers all over the world. While this service is being considered valuable and important to the free and open source software community, many users wish to be sure about the origin of the package and its content before installing the package. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or rpm package: 1) md5sums as provided in the (cryptographically signed) announcement. 2) using the internal gpg signatures of the rpm package. 1) execute the command md5sum <name-of-the-file.rpm> after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security(a)suse.de) the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, where <file.rpm> is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build(a)suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the toplevel directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion. All SuSE security announcements are sent to this list. To subscribe, send an email to <suse-security-subscribe(a)suse.com>. suse-security-announce(a)suse.com - SuSE's announce-only mailing list.
