-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SUSE Security Announcement Package: cvs Announcement-ID: SuSE-SA:2004:013 Date: Wed May 19 13:00:00 MEST 2004 Affected products: 8.0, 8.1, 8.2, 9.0, 9.1 SuSE Firewall on CD 2 - VPN SuSE Firewall on CD 2 SuSE Linux Enterprise Server 7, 8 SuSE Linux Office Server UnitedLinux 1.0 Vulnerability Type: remote command execution Severity (1-10): 6 SUSE default package: No. Cross References: CAN-2004-0396 Content of this advisory: 1) security vulnerability resolved: buffer overflow in cvs problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds: - neon - subversion - kdelibs/kdelibs3 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The Concurrent Versions System (CVS) offers tools which allow developers to share and maintain large software projects. Stefan Esser reported buffer overflow conditions within the cvs program. They allow remote attackers to execute arbitrary code as the user the cvs server runs as. Since there is no easy workaround we strongly recommend to update the cvs package. 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 neon packages are available on our ftp servers. CAN-2004-0398 has been assigned to this issue. - subversion New subversion, subversion-devel and subversion-server packages are available on our ftp servers, fixing a stack overflow issue while handling REPORT queries. CAN-2004-0397 has been assigned to this issue. - kdelibs/kdelib3 New kdelibs and kdelibs3 packages are currently being tested, fixing the vulnerabilities described in http://www.kde.org/info/security/advisory-20040517-1.txt. New packages will soon be available on our ftp servers. ______________________________________________________________________________ 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.

Squid crashing
by Watson, Michael 20 May '04

20 May '04

Greetings, I'm not entirely sure this is the right place to post a question like this, but if anyone has any suggestions, I'd love to hear them. I'm running squid on suse 9.0 professional, and have run into a problem. Every couple of days, squid seems to stop working. Users attempt to connect to the web through squid, but never see their target webpage. If I reboot the system, squid starts working again, but a few days later, the same thing seems to happen all over again. I ran squid for a couple of years on red hat, and never ran into this problem--it started when I made the move to suse. I am looking into adjusting squid's error logging to help track down this problem, but in the meantime I thought I'd also ask if anyone is aware of any known issues running squid on suse 9.0. Thanks, Mike Watson mwatso(a)lsuhsc.edu

Where to report SPAM, scams, viruses, etc... (when it is illegal)
by J. Theriault 18 May '04

18 May '04

Hello list, This is more a procedural question than a direct security but relevant none the less: Where (for various countries) can you report spam, scams, dialers, viruses, or other computer crimes? Lately, the spam I have been receiving has been more and more offensive and illegal in it's offerings (many obious bank fraud scams, pirated software, etc...) and when left with only an unlisted phone number or domain it can be difficult to know where to send the information to have the proper action taken, especially if it's a foreign country. At the moment I report major problems (such as domains offering bank scams) to the ISPs in question and ignore most "normal" spam. Thanks, J. Theriault administrator(a)maginetworks.com

cannot access ftp server -- getpeername (in.ftpd): Transport endpoint is not connected
by Matthias Hupp 17 May '04

17 May '04

Hello, maybe one of you can help me with this problem. I am posting it here because it seems to be caused by a security mechanism. The ftp server on a web/mail/inet-gateway machine I am taking care of can no longer be accessed, ever since one of the secretaries decided to switch it off and on again because she could not access her files on a Windows server. I have made some changes on the ipchains rules since then, but ftp is open on the internal interface. Anyway, access is possible neither from the LAN, nor from the machine itself when I am logged on via ssh. I get this message on the shell: *** # ftp localhost Trying ::1... ftp: connect to address ::1: Connection refused Trying 127.0.0.1...

Firewall Check
by Michael Rauter 17 May '04

17 May '04

Hi I've found an interesting Program to check firewalls. It demonstrates the ability to connect to internet via other programs which are allowed to connect. (Trojan Horses) Is it possible to block the program from accessing the internet via a stand-alone router ? http://www.pcinternetpatrol.com/downloads/pcaudit.exe Is this simply a program to panic users or is there a serious danger ?

OT: OpenPBS / GridEngine configuration on SuSE 9.0
by Simon Oliver 17 May '04

17 May '04

Sorry for the OT post (I did try the suse-linux-e list without any response) - I'm hoping someone here can help or knows where I can post this message and actually get a response. I'm trying to use OpenPBS on SuSE 9.0. I would like to use the SuSE configured version rather than a custom compile. Normally I check the README.SuSE (under /usr/share/doc/packages/) for a package before proceeding but in this case it's odd - it seems to be a tar file that contains two files: -rw-r--r-- nashif/users 2298 2002-07-29 00:09:00 SuSEconfig.pbs -rw-r--r-- nashif/users 1068 2002-08-04 15:42:55 pbsmom.init There are no instructions or documentation on how OpenPBS has been set up to run (as a server) on SuSE 9.0. There are configuration files in the /etc/sysconfig directory, but there is no documentation on what the variables do or what their effect is. I could try reading the init scripts but surely the relevant information is documented somewhere? /etc/sysconfig/pbs_server /etc/sysconfig/pbs_mom A similar problem exists for GridEngine. Please can you provide a link to the documentation, or any help in this regard? TIA -- Simon Oliver

Network Device Problem
by Robert Rottscholl 17 May '04

17 May '04

Dear List, I've a certain security problem. My SuSE 9.1 box has two network cards (ne2k-pci, sundance). I also run SuSEfirewall. Everytime my box starts the network devices are assigned to a different interface, e.g. 1. Boot: sundance -> eth0 ne2k-pci -> eth1 2. Boot: ne2k-pci -> eth0 sundance -> eth1 3. Boot: the other way round.... So sometimes my services (like bind, squid, vftpd) listen on the world devices (which is not wished) and sometimes they listen on the internal network interface (wished configuration). Now anyone can attack my services, because SuSEfirewall offers them to world outside. Does anybody know this bug/poblem? Greets Robert

online_update login problem
by Matt Jurcich 17 May '04

17 May '04

Hey all, I'm trying to get online_update working so I can set it up with cron to download patches automatically. I have documentation on how to do this. My issue is when I run online_update from the command prompt, it displays the product, and version, etc, then returns an error: Error retrieving patches: ERROR(Media:login failed) I checked my /etc/sysconfig/onlineupdate file and the correct login and password are in there. Running Online Update from YAST2 in graphical mode manually works just fine. I used the -D switch for debug mode and it didn't reveal any additional information, which I thought was odd. Thanks for any assistance on this one! -m --- matt jurcich, networkologist (IC) invisik corporation, for IT ingenuity

SUSE backporting
by Matt Jurcich 16 May '04

16 May '04

Hey all, I've a SUSE Standard Server 8.0 and noticed the latest version of ssh that Online Update gives me is only 3.4.x ! The most recent out there is 3.7.x. What gives? Shouldn't these be up to date, especially as I'm on maintainence and am regularly updating from the SUSE server through Online Update in YAST? Thanks much... -m --- matt jurcich, networkologist (IC) invisik corporation, for IT ingenuity

by Frank Stuehmer 14 May '04

14 May '04

Hello list, I've just performed an online update for SuSEfirewall2 on Suse 9.1. Personal settings was before update FW_MASQ_NETS="\ 192.168.100.0/24,0,0,tcp,22 \ 192.168.100.0/24,0,0,tcp,25" after update FW_MASQ_NETS="\ ## Type: yesno ## Default: yes 192.168.100.0/24,0,0,tcp,22 \ 192.168.100.0/24,0,0,tcp,25" If you try to restart SuSEfirewall2 it fails (of course). Next machine I will edit the file before restart firewall. Frank

The buffer overflow can be abused to execute commands remotely in conjunction with other systems (CGI, ...). New packages are available on our FTP servers. - apache2/-devel/-doc/-example-pages/-prefork/-perchild/-worker, apr, libapr0 These updates fix a memory leak in the mod_ssl module of apache2 (CAN-2004-0113), a possible remote DoS attack on accessing rarely used listening ports (CAN-2004-0174), and a problem with unescaped special characters in log files that could present a security hazard for terminal emulators (CAN-2003-0020). New packages are available on our FTP servers. - xine, xine-lib, xine-ui A buffer overflow exists in the xine library. Attackers could execute arbitrary code as the user utilizing the xine library. More information can be found on http://www.xinehq.de/index.php/security/XSA-2004-3. New packages are available on our FTP servers. - sysconfig This update fix the restart of the firewall after a dialup connection is established. Without this restart, all ports are closed on the dialup interface and the connection seems to be not working. This bug affects SUSE LINUX 9.1 only. New packages are available on our FTP servers. - clamav The ClamAV project recently changed the format of their virus definition database files to support detection of new sorts of viruses. This update is needed to make use of the files in the new format. New packages are available on our FTP servers. - exim The exim mailer contains a buffer overflow in its header parsing functions which may allow remote attackers to execute arbitrary code. Only installations with the "verify=header_syntax" config option enabled are vulnerable to this attack. SUSE Linux is not configured that way by default. CAN-2004-0400 has been assigned to this bug. New packages are available on our FTP servers. - utempter This updates addresses a possible symlink attack while using tty device files. This bug may lead to a local root compromise. New packages are available on our FTP servers. - busybox Busybox does not handle netlink sockets correctly, which allows local attackers to spoof netlink messages to the busybox process New packages are available on our FTP servers. - monit There exists security vulnerabilities in the monit HTTP interface, which could allow an attacker in the worst case to gain root access to the system. This issue only affects monit if monit is started with http server support. See http://www.tildeslash.com/monit/secadv_20040305.txt for details. New packages are available on our FTP servers. - ethereal Several buffer overflows in the ethereal code were fixed. These buffer overflows can be used to gain remote access to a system where ethereal is running on. (CAN-2004-0176, CAN-2004-0367, CAN-2004-036) New packages are available on our FTP servers. - kphone The kphone update fixes a possible denial-of-service attack in SIP client code. New packages are available on our FTP servers. ______________________________________________________________________________ 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>.

Machines inside the trusted nets are allowed to access your net. You can restrict netmask, protocol and ports to restrict access to your network. FW_TRUSTED_NETS="192.168.108.0/24" would allow full access from "other companies network" to "my network". You can also enter single addresses here if needed.

Suse Firewall 2 and VPN access
by Jorge Canelhas 14 May '04

14 May '04

Hi all I have my network accessing the internet using another companies network, to separate my network (192.168.100.0 on eth0) from the other companies network (192.168.108.0 on eth1) i use a linux computer with suse firewall 2 with masq suport and squid, obvious that the other companies network is on the untrusted device. The problem came when we started to use the others company VPN servers that give the VPN clients their own networks IP (192.168.108.0). Question : How can i allow a range of IPs from the other companies network to go through my firewall ? Litle net drawing : INET ----- other companies network -----///// FW \\\\\\ ----- my network ... 192.168.108.0 192.168.100.0 Thanks in advance Jorge Canelhas ------------------------- Are u a retro computing fan ? check : http://www.retroreview.com

Imho, since it is used both internally and externally, then it ought to be in the DMZ. It can be a potential source of compromsie from external sources if placed on the internal network.

place for db-server
by Christian Mang 13 May '04

13 May '04

Hi List, I am not sure about the right place for our database server. We have an external and an internal firewall (SuSE 9.0) with a DMZ. The application server is used for internal and external work. It needs a database server on its own machine. Should I take it in the DMZ or in the internal network? What is the (security related) best decision? Thanks Christian

On Tuesday 11 May 2004 19:10, Manuel Balderrábano wrote: > Sure! But by that option all connections will appear as comming from the > firewall. I may have totally misunderstood what you're trying to achieve. I thought you were trying to route incoming traffic to your firewall to port 80 on a machine in your DMZ and that this machine had a private (non-routable) IP. With the FW_FORWARD_MASK the source address of incoming traffic to your webserver won't be rewritten, only the destination address is. Outgoing traffic will have the source address rewritten to the IP of your firewall, but wasn't that is the whole idea about PAT? Best regards, Arjen
