how to keep nimda and code red from filling apache logs

by Mathias Homann

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]

problem with SQUID

by payam payami

Hi, I use suse 7.3 Internal network connect to internet by setting port 3128 in IE but when i set in squid.conf for authenticate_program that get windows login for users, IE don't get any windows and Internal network (clients) connect to internet normally without login I set these options in squid.conf: authenticate_program /usr/sbin/pam_auth acl password proxy_auth payam acl users src 192.168.1.0/255.255.252.0 http_access allow users http_access allow password Is here any problem with this configuration that IE can't get windows login when want to browsing? Thanks for your help, Payam __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable. Sign up now. http://mailplus.yahoo.com

Fwd: RE: [suse-security] My SuSEFirewall blocks something than my LAM can not surfing in internet anymore.

Hi You need to put in /etc/resolv.conf a DNS server! This is normally your ISP servers.

Hi Prabu, Sorry to say so, but this trace shows nothing more than a connection-trace of your ssh-session (DPT=22 ...). Don't tail /var/log/messages, it's quite big and gets filled really fast. Do a "cat /var/log/messages|grep DTP=80|grep -v DST=192.168.23.10" in order to get all the outgoing http-stuff. so long, Stefan btw. I'm called Stefan - it's a bit queer here in Austria, we always put the last name in front ;-) > From: Prabu Subroto [mailto:prabu_subroto@yahoo.com] > Dear my friend, Peer... > > Today morning, it happened again.

224.0.0.1 messages

by suse-sec＠orcaoffice.com

Hi, I have the following in my /var/log/warn file : Feb 28 13:51:37 plato kernel: SuSE-FW-ILLEGAL-TARGET IN=ppp0 OUT= MAC= SRC=xx.xx.xx.xx DST=224.0.0.1 LEN=28 TOS=0x00 PREC=0x00 TTL=1 ID=55846 PROTO=2 I've read that this message is basically a misconfigured router from my DSL supplier. However what I'd like to know is, what can I add to my SuSEFirewall config so that I can skip logging these messages (i.e. ignore any 224.0.0.1 messages )? Thanks CPH

My LAN user can not surfing in internet after a couple of hours.

by Prabu Subroto

Dear my friends.... I am using SuSE Linux 8.1 for our internet gateway. I installed Squid, SuSEfirewall2 and ip-masquerading on the Linux-Box. It runs properly after a couple of hours in one day but than my LAN user can not surfing in internet anymore. If the problem comes, my LAN user still can use e-mail through IP-Masquerading but not http. If the problem comes than I have to restart the SuSEfirewall2 with: " SuSEfirewall2 stop SuSEfirewall2 start " After restarting the SuSEfirewall2 than my LAN user can surfing in internet back (again). If I restart my SuSEfirewall I got this error message: " proxy:~ # SuSEfirewall2 stop Removing filter rules ... SuSEfirewall2: clearing rules now ... done proxy:~ # SuSEfirewall2 start Warning: FW_SERVICE_DNS defined, but no DNS server found running! proxy:~ # " Here is my "/var/log/messages": "

SuSE Security Announcement: hypermail (SuSE-SA:2003:0012)

by Thomas Biege

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: hypermail Announcement-ID: SuSE-SA:2003:0012 Date: Thursday, Feb 27th 2003 18:30 MET Affected products: 7.1, 7.2, 7.3, 8.0, 8.1 Vulnerability Type: remote system compromise Severity (1-10): 4 SuSE default package: no Cross References: CAN-2003-0025 Content of this advisory: 1) security vulnerability resolved: several bugs after source code review problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - vnc - w3m 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information Hypermail is a tool to convert a Unix mail-box file to a set of cross- referenced HTML documents. During an internal source code review done by Thomas Biege several bugs where found in hypermail and its tools. These bugs allow remote code execution, local tmp race conditions, denial-of-service conditions and read access to files belonging to the host hypermail is running on. Additionally the mail CGI program can be abused by spammers as email- relay and should thus be disabled. There is no temporary fix known other then disabling hypermail. Please download and install the new packages from our FTP servers. 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 -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web.

New packages are currently being tested and will be available on our FTP servers soon. - w3m The textbased web-browser w3m does not properly escape HTML tags. A malicious HTML page or img alt attribute may lead to information leakage. New packages will be available soon. ______________________________________________________________________________ 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 un-installed 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 top-level 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. Only SuSE's security announcements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe(a)suse.com>. For general information or the frequently asked questions (faq) send mail to: <suse-security-info(a)suse.com> or <suse-security-faq(a)suse.com> respectively. ===================================================================== SuSE's security contact is <security(a)suse.com> or <security(a)suse.de>. The <security(a)suse.de> public key is listed below. ===================================================================== ______________________________________________________________________________ The information in this advisory may be distributed or reproduced, provided that the advisory is not modified in any way.

SuSE Security Announcement: openssl (SuSE-SA:2003:011)

by Roman Drahtmueller

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: openssl Announcement-ID: SuSE-SA:2003:011 Date: Wednesday, Feb. 26th 2003 15:20 MET Affected products: 7.1, 7.2, 7.3, 8.0, 8.1 SuSE Linux Database Server, SuSE eMail Server III, 3.1 SuSE Linux Enterprise Server 7 SuSE Linux Enterprise Server 8 SuSE Linux Firewall on CD/Admin host SuSE Linux Connectivity Server SuSE Linux Office Server Vulnerability Type: remote attack on encryption Severity (1-10): 5 SuSE default package: yes Cross References: CAN-2003-0078 Content of this advisory: 1) security vulnerability resolved: openssl problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - vnc - w3m 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information OpenSSL is an implementation of the Secure Sockets Layer and Transport Layer Security protocols and provides strong cryptography for many applications in a Linux system. It is a default package in all SuSE products. A security weakness has been found, known as "Vaudenay timing attack on CBC", named after one of the discoverers (Brice Canvel (EPFL), Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and Martin Vuagnoux (EPFL, Ilion)). The weakness may allow an attacker to obtain a plaintext data block by observing timing differences in response to two different error cases (cipher padding errors vs. MAC verification errors). In order to exploit this vulnerability, the attacker has to meet certain requirements: The network connection between client and server must be of high quality to be able to observe timing differences, the attacker must be able to perform a man-in-the-middle attack, the transactions must repeatedly contain the same (encrypted) plain text block (such as a pop password or alike), and decoding failures in the SSL layer must not be propagated to the application that is using the SSL connection. These exploitation conditions considerably reduce the security risk imposed by the vulnerability. However, we recommend to completely remedy this weakness by installing the update packages for your system according to the following guidelines. There does not exist any temporary workaround for this problem other than applying the update packages. Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. SPECIAL INSTALLATION INSTRUCTIONS: ==================================== Please update your openssl package using the command rpm -Fhv <package.rpm> The operation of this command must not be interrupted! An interrupted update of the openssl package may cause large protions of your system to fail. After performing the update, it is adviseable to run the command "ldconfig" to update the shared library loading cache. After the update, running processes in your system will continue to use the shared libraries from the old package before the update. Generally, it is necessary to restart all of these processes to completely fix the vulnerability in your system. The command lsof -n 2>/dev/null | grep RPMDELETE can be used to find the binaries and processes that still use the old shared libraries. In all cases, the next reboot of the system will cause the old shared libraries to be completely removed from the system. Alternatively, a transition to runlevel 1 (single user mode) and back to the default runlevel will have the same effect.

New packages are currently being tested and will be available on our FTP servers soon. - w3m The textbased web-browser w3m does not properly escape HTML tags. A malicious HTML page or img alt attribute may lead to information leakage. New packages will be available soon. ______________________________________________________________________________ 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 un-installed 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 top-level 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.
