AW: [suse-security] Is it possible to return something, so Nimda would crash?

Hi, you can always ask ARIN (whois whois.arin.net <ip>) or (in Europe) RIPE (whois.ripe.net), it will give you the administrative contact(s) for the netblock the questioned ip is in. I hacked a small shell script which takes an access_log file from my servers, extracts the nimda-type requests, does a lookup of the admin's email and sends him _one_ mail (with URLs pointing to NIMDA informations and how to remove it). Can't tell how successful I was with this attempt, but sent out 350 mails and received no "shut up"... Thomas -----Ursprungliche Nachricht----- Von: Alexey N.

[suse-security] snort going mad, portscan against myself...?
by Markus Kohli 24 Sep '01

24 Sep '01

Hi together! I just figured out how to run snort (altough it doesn't start at boot-up, hell knows why...). Now it keeps telling me, that there is a portscan against myself from my machine running. Look at this: [**] [100:1:1] spp_portscan: PORTSCAN DETECTED from 10.0.3.19 (THRESHOLD 4 connections exceeded in 7 seconds) [**] 09/24-23:52:42.477424 [**] [100:2:1] spp_portscan: portscan status from 10.0.3.19: 6 connections across 6 hosts: TCP(5), UDP(1) [**] 09/24-23:53:58.678712 [**] [100:2:1] spp_portscan: portscan status from 10.0.3.19: 1 connections across 1 hosts: TCP(0), UDP(1) [**] 09/24-23:54:03.679551 [**] [100:2:1] spp_portscan: portscan status from 10.0.3.19: 1 connections across 1 hosts: TCP(0), UDP(1) [**] 09/24-23:54:08.689307 [**] [100:2:1] spp_portscan: portscan status from 10.0.3.19: 2 connections across 2 hosts: TCP(1), UDP(1) [**] 09/24-23:55:00.534798 And I swear, I'm not running any nmap or anything similar, and haven't been running since the last reboot... Could anybody help me please? TIA kind regards markus

security problem with kdm settings
by Bob Vickers 24 Sep '01

24 Sep '01

Hello, I believe I have found a bug in KDE which has minor security implications. Twice now I have found that my local customisations of KDM have disappeared, and this is very irritating. The default KDM settings are not appropriate for terminals in public areas because: (a) a complete list of valid users is displayed (b) the banner includes the word "Welcome", and I have often been advised that you should not welcome users until after they have passed authentication (whether this advice is good is beside the point!). I believe that the settings revert when I install other software; perhaps when SuSEconfig runs. The sequence of events was : (1) start kcontrol, then become root and customise the login process (2) success, login now OK. (2) I noted that my customisation had changed /opt/kde2/share/config/kdmrc so I copied this to a new file /etc/opt/kde2/share/config/kdmrc in the hope of making the change permanent (3) I installed other software (galeon and netscape6). (4) Customisations have been lost, and /opt/kde2/share/config/kdmrc has reverted to default (5) I copied /etc/opt/kde2/share/config/kdmrc to /opt/kde2/share/config/kdmrc and things are OK again (until next time). I may be doing some things wrong, because I can't find any documentation about customising KDE other than the painstakingly slow GUI method. /etc/kderc contains dir_config=/etc/opt/kde2/share/config:/opt/kde2/share/config though my experience suggests this has no effect. I am running kdebase-2.1.1-89 on SuSE 7.2 Bob ============================================================== Bob Vickers R.Vickers(a)cs.rhul.ac.uk Dept of Computer Science, Royal Holloway, University of London WWW: http://www.cs.rhul.ac.uk/home/bobv Phone: +44 1784 443691

I am an American and very patriotic. But, I believe that this line of communication should be stopped. The initial response message was uncalled for and should have been ignored. Please do not get into a ridiculous spat here and lets stay on topic of SuSE at least (if not exclusively security).

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: wmaker/WindowMaker Announcement-ID: SuSE-SA:2001:032 Date: Thursday, September 20th 2001 15:10 MEST Affected SuSE versions: (6.0, 6.1, 6.2,) 6.3, 6.4, 7.0, 7.1, 7.2 Vulnerability Type: remote privilege escalation Severity (1-10): 5 SuSE default package: no Other affected systems: all Unix systems running Window Maker < 0.65.1 Content of this advisory: 1) security vulnerability resolved: Window Maker 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 window manager Window Maker was found vulnerable to a buffer overflow due to improper bounds checking when setting the window title. An attacker can remotely exploit this buffer overflow by using malicious web page titles or terminal escape sequences to set a excessively long window title. This attack can lead to remote command execution with the privileges of the user running Window Maker. A temporary fix does not exist; we recommend to update your system with the new RPM from our FTP server. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Uhv file.rpm" to apply the update. After installing the updated RPM - run /sbin/SuSEconfig (the central configuration utility in SuSE Linux distributions) - restart your window manager. If this is not possible for configura- tional reasons, restart your x-session. i386 Intel Platform: SuSE-7.2 ftp://ftp.suse.com/pub/suse/i386/update/7.2/xwm1/WindowMaker-0.64.0-82.i386… 0f5508e10089deecf34b51ab8c007bbf source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.2/zq1/WindowMaker-0.64.0-82.src.r… 6472b87eb8a841d5cefe4f0889f9b4e1 SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/xwm1/WindowMaker-0.62.1-25.i386… 39c69fab92923eca0cf1f0e077232fef source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/WindowMaker-0.62.1-25.src.r… a8c32f85125bbe7bf041335100e447b8 SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/xwm1/wmaker-0.62.1-42.i386.rpm d825fa6cd78643e880bb89464594a464 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/wmaker-0.62.1-42.src.rpm bd6e55a9b16e836065f59b4dc824416f SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/xwm1/wmaker-0.61.1-59.i386.rpm 7de5a334c4fbbeb6ef3d79d197a585c1 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/wmaker-0.61.1-59.src.rpm 4471d22b705b8b24a1808729a32d1764 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/xwm1/wmaker-0.61.1-59.i386.rpm 8c8453b37e7b69008be2be4929a62d80 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/wmaker-0.61.1-59.src.rpm 0c96f81234e787a48b8d2df4e698843a Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/xwm1/WindowMaker-0.62.1-17.spa… c19bc73ccc235bbd35d1e8953cfbabbb source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/WindowMaker-0.62.1-17.src.… e60425cb8ae38b16a3aac3fa23a6c54f SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/xwm1/wmaker-0.62.1-2.sparc.rpm 9f0a23eddb8b9dbfc07288871388ff34 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/wmaker-0.62.1-2.src.rpm a95d995b1ea164b8c93a9fc308f703d1 AXP Alpha Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/axp/update/7.1/xwm1/WindowMaker-0.62.1-23.alpha… 55cf56c7bea8fa3e9cf7ca2c90457249 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.1/zq1/WindowMaker-0.62.1-23.src.rpm 7b5bc50ad9e854dc2858a1b0a08385d5 SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/xwm1/wmaker-0.62.1-5.alpha.rpm 6e7e01c1a1ef1e2ac751638dd7e31d21 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/wmaker-0.62.1-5.src.rpm 2ee34d67aba5c06878623e3ca50f47d1 SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/xwm1/wmaker-0.61.1-57.alpha.rpm dcbfdaf729cb823046f3dc6e913fcf1b source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/wmaker-0.61.1-57.src.rpm 3d045c4fd65d2ce9b69a1890d71fd59a SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/xwm1/wmaker-0.61.1-57.alpha.rpm 6c17c78ef0fe2971b29fe1a2300c4fc3 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/wmaker-0.61.1-57.src.rpm f01b2923ebc6e4e6a52b75e8597cbe50 PPC PowerPC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/xwm1/WindowMaker-0.62.1-18.ppc.r… 00f099cc26983691641ed041441abfc2 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/WindowMaker-0.62.1-18.src.rpm 1941b4c46eeb3e4fe4a7e3a1c79ae8a5 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/xwm1/wmaker-0.62.1-49.ppc.rpm f5ef503d073a7e9e34cf28e4eb56fbaa source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/wmaker-0.62.1-49.src.rpm 362468904bd119c44f2c2baa1312a116 SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/xwm1/wmaker-0.61.1-56.ppc.rpm 0408f29d40eebf5bbc84bdcf14a03c5f source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/wmaker-0.61.1-56.src.rpm 50c1a727aec53feb76f451854657b6c8 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - SuSE Linux distributions do not contain the sftp-server as described by Peter W <peterw(a)usa.net> (Message-ID: <20010918082406.M14947(a)usa.net>) on the bugtraq mailing list and are therefore not vulnerable to the problems found. - A new worm called "Nimda" has been reported in the wild. It attacks IIS webservers and uploads a file called "readme.eml" which is being downloaded by the client's browser. Some versions of the Internet Explorer even execute this file without the user's knowledge. A temporary workaround for sites that use a squid proxy to access the internet would be to add these three lines to the /etc/squid.conf file: # filter Nimda worm files: acl nimda urlpath_regex -i \.eml$ acl nimda urlpath_regex -i \.nws$ http_access deny nimda Do not forget to reload your squid server (/usr/sbin/rcsquid reload)! ______________________________________________________________________________ 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 advise against subscribing to 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.

router / ipchains
by Michael Neumann 22 Sep '01

22 Sep '01

Hi all! I want to protect our network with a firewall that should run on a SuSE machine (kernel 2.2 stable). There is a router that provides a permantent DSL connection to the net. Normaly this router is the gateway for all machines on the local net - but not I want to put a firewall between. The network has official ip addresses and all machines shall use these, which means that I do not want to have masquerading. So I have put the firewall machine between router and local net. I have switched on ip_forwarding and - for testing - have set up all ipchains to ACCEPT. Now it should route/forward everything, yes? But it doesn't. I can ping the firewall machine both from outside and from inside. But I cannot reach another host in the network from outside (and the other way around). When I try to ping a host in the network from outside I get a answer from my dsl router that this host is not reachable. Maybe the problem is here, I don't know... Do you have an idea? Thanx a lot! Michael
