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.

Re: is SuSE going to implement libsafe?

Hi, >I have just read an Bell Labs anouncement, that they are going to release >libsafe under GNU licence, and that some major Linux distros are going to >be using it. SuSE was not amongst them, why is that? I think that libsafe would >be a good echnacement against buffer overflow. > >Anouncement is on: >http://www.bell-labs.com/news/2000/april/20/1.html just because something new pops up please be careful with questions like "when will you implement it?" ;-) There are several questions to ask: a) is it STABLE and does it NOT affect the stability of other programs? b) does it bring additional security problems into the system? c) is the security protection effective? Well, of course the SuSE Security Team already reviewed libsafe. Here are the answers: a) unsure. it would have to be tested very intensive. this was not done yet. b) the code might have vulnerabilities, however the protection gained is higher even if a vulnerability would be present c) okay, now the tough part: libsafe is a dynamic library which is set in the environment which checks several dangerous functions, which can be a security problem. Because it is a dynamic library, it is NO protection against local attackers, just against remote attackers on network services. (if an attacker wants to attack a local suid file, he would just reset his library path environment). Next thing: it does not check for all known vulnerabilites. It even doesn't protect against all buffer overflows, It just protects against *some* overflows. those which happen because of insecure use of strcat/strcpy etc. summary: I can not remember a vulnerability in a network service for the last year which this tool would have prevented. Therefore: as long as this tool is not enhanced to also protect open/fopen calls against symlink/hardlink/pipe attacks, several more buffer overflow types, system/exec* function protection etc. it is not useful to use this tool. I would rather propose to use the secumod module which comes with SuSE Linux since 6.3 and maybe the secure-linux kernel patch from www.openwall.com - these two tools enhance your security. (and btw, install seccheck, hardensuse and firewals and use them - then your security is very high) Greets, Marc -- Marc Heuse, SuSE GmbH, Schanzaeckerstr. 10, 90443 Nuernberg E@mail: marc(a)suse.de Function: Security Support & Auditing "lynx -source http://www.suse.de/~marc/marc.pgp | pgp -fka" Key fingerprint = B5 07 B6 4E 9C EF 27 EE 16 D9 70 D4 87 B5 63 6C

SuSE Security Announcement: netscape (SuSE-SA:2000:48)
by Roman Drahtmueller 13 Dec '00

13 Dec '00

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: netscape Announcement-ID: SuSE-SA:2000:48 Date: Thursday, November 30th, 2000 19:00 MET Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0 Vulnerability Type: clientside remote vulnerability Severity (1-10): 4 SuSE default package: yes Other affected systems: systems w/ netscape versions before 4.76 Content of this advisory: 1) security vulnerability resolved: netscape 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 Michal Zalewski <lcamtuf(a)DIONE.IDS.PL> has found a buffer overflow in the html parser code of the Netscape Navigator in all versions before and including 4.75. html code of the form <form action=foo method=bar> <input type=password value=long string here> more form tags </form> can crash the browser. It may be possible for an attacker to supply a webpage that executes arbitrary code as the user running netscape. As of today, no exploit code is known to exist in the wild. SuSE provides an update package for the vulnerable software. It is recommended to upgrade to the latest version found on our ftp server as described below. The update package introduces Netscape version 4.76. NOTE: Please note that Netscape-4.76 is not available for the glibc-2.0-based SuSE Distributions SuSE-6.0 and 6.1 because Netscape doesn't provide any binaries for the glibc version in these distributions (glibc-2.0). For SuSE-6.0 and 6.1, we provide a libc5-based version of netscape-4.76 which runs smoothly on all i386-based SuSE distributions 6.x and 7.x, provided the package shlibs5 is installed. The package can be found in the update/5.3 directory on our ftp server (see below). There are no packages available for platforms other than i386. NOTE: The packages on our ftp servers date back to October 31st. Since there is no release notes or README file with equivalent content in the netscape tarball, SuSE security was not aware of the fact that this release of netscape fixes the known problems. This information can be obtained from (along with information about other bugfixes) http://home.netscape.com/eng/mozilla/4.7/relnotes/windows-4.76.html . Please choose the update package(s) for your distribution from the URLs listed below and download the necessary rpm files. Then, install the package using the command `rpm -Uhv file.rpm´. rpm packages have an internal md5 checksum that protects against file corruption. You can verify this checksum using the command (independently from the md5 signatures below) `rpm --checksig --nogpg file.rpm', The md5 sums under each package are to prove the package authenticity, independently from the md5 checksums in the rpm package format. Intel i386 Platform SuSE-7.0 SuSE-6.4 SuSE-6.3 SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/7.0/xap1/netscape-4.76.glibc21.i386… 7ccebaca7df0937a3c08fc30a27af858 SuSE-6.1 SuSE-6.0 ftp://ftp.suse.com/pub/suse/i386/update/5.3/xap1/netscape-4.76.libc5.i386.r… 3c4f06c5fea4755083524eb135627380 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - ssh/openssh Several inconsistencies and configuration bugs have been introduced in the SuSE rpm packages for the update of openssh (SuSE-SA:2000:47) that cause the openssh software to not work as reliably as usual. The packages are about to be reworked, the openssh announcement will be reissued. - pidentd The in.identd daemon on SuSE distributions can be crashed remotely. We're working on a fix. - bash1 bash, version 1, handles temporary files in an unsafe manner that allows a local attacker to overwrite arbitrary files as the user running a bash1 with input redirection of the "<< EOF" style. The bash1 package is not used per default in SuSE-distributions. We're working on a fix (update packages). - tcsh The paragraph above about bash version 1 applies to the tcsh as well, in all versions. The tcsh is not used by SuSE scripts. ______________________________________________________________________________ 3) standard appendix: SuSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - general/linux/SuSE security discussion.

RPM-Update on all boxes in a LAN
by gtschakert＠gmx.de 05 Dec '00

05 Dec '00

Hi, after reading the last security-announcement I ask myself if there is a tool to update the new rpm automatically to all the boxes in my LAN. What I want to do is the following: I recieve the security-announcement: I decide to install or not and download the rpm. I start a script, which will install the rpm to the boxes of my choice. I don't want to login on every box, install the rpm and go to the next box. I hoped alice would do things like that, but I think alice is only a tool for new installation (and you have to make a floopy-disk or a CD). And I think, some month ago, I have read about a scripting-language for system administrators, but I don't remember where. Anybody, who can help me.

Hello: Im a newbie at Linux. Recently setup a SuSE 7.0 LinUx box and had everything going well. Until, I made a few changes in the /etc/rc.config and somehow disabled my FTP Services. I've also made changes in my etc/rc.config.d/firewall.rc.config too and now I totally blocked out of my ftp services. I know I'm not being clear on the info I've given but can anyone help me get started with re-enabling ftp services again. Is it? start Inetd="yes"?? start Proftpd="yes"????

any nntp proxy ?

30 Nov '00

Hi, I need to install a nntp proxy on my suse 6.3, and I tried acmennrp. When I start it, it justs stops without a single (error) message; I bet there is something missing. Since I cannot read java (sorry),and cannot find a clue of a documentation neither any logged message anywhere (yes, syslogd is configured and working all right), what else can I do ? Does anybody knows about using acmennrp (proxy mode only), or any other SW that woul do it ?

How secure is sendmail
by Max Lindner 30 Nov '00

30 Nov '00

Hi! I'm must make a decision wether to install sendmail or not. I've heard that sendmail is unsecure, but it is also used very often. My case would be a server without really sensitive data, only public html-files on apache and so on. What do you think about sendmail? Do you know other mail-deamons which are more secure? Thanks for help, Max Lindner

I just ran the checkneverlogin command out of the seccheck.rpm. There I realized that the script warns me about users which have the shell set to /bin/false which should be perfectly okay. Or do I have to erase the /bin/false in the /etc/shells file in order for the script to work right? Thanks Raffy

AW: [suse-security] Scanning encrypted Mails
by Stiefenhofer, Marek ECOFIS 30 Nov '00

30 Nov '00

I don't know about products, but here're some ideas: You need clients that encrypt mails with two public keys: first the usual encryption by the recipients public key. Second encryption by your scanners public key. So your scanner is able to decrypt the Email, scan it and probably drop it if it is infected. But you've still the problem, that the scanners private key must be located in a very safe environment. bye marek

Scanning encrypted Mails
by Peter Lange 30 Nov '00

30 Nov '00

Hi folk, I look for a solution to encrypt/decrypt mails. But, I have to scan them for malicous code also. All suggestions are welcome. I would prefer a centralized solution (8 Branches 500 Mails per day) I thought about a second DMZ to encrypt/decrypt on something like a keyserver. Then forward to the Contentscanner and then if the mails are clean forward to the internal Mailserver. Anybody out there know about a "keyserver"? thanks Peter

Thomas Biege, Sebastian Krahmer, Adrian Schröter and myself have been looking at the code, each of us having found a glitch (the multithreaded implementation makes debugging an interesting adventure! :-). It turned out that the daemon dies because of a misinterpretation of the return value of vsnprintf() (which was subject to a change in glibc2.1). Upon detecting that the buffer is too short to keep the data, the daemon decides to "int *p = (int *) NULL; *p = 4711;", or, in other words, segfault and commit suicide. This is bright because a return address on the stack that might have been overwritten is not used (An actual buffer overflow doesn't take place, though.). OTOH, it's not very bright since the auth service is denied as a consequence of the daemon shooting itself in the foot. The risk imposed by the crashed daemon is considerably low. Personally, I find that this behaviour suits the necessity and the usefulness of the protocol itself. > Who's vulnerable ? > ============== > This vulnerability has been tested on SuSE version 6.x and version > 7.0. Previous versions may also be affected. Further testing will > reveal whether other Linux distributions are vulnerable. in.identd in older releases of the SuSE Linux distribution can be crashed, too. Other vendors ship this daemon, too, and will release advisories about the issue soon. With the release of the SuSE-7.0 distribution, the in.identd daemon is contained in a seperate package - before 7.0, it was included in the nkitb package. We will provide updates for the 6.x and 7.0 distributions as usual, but it will take another few days since changes in the nkitb package need thorough testing. In the meanwhile, you may want to disable the service by changing START_IDENTD="yes" # default to START_IDENTD="no" in /etc/rc.config and by killing the daemon (`killall in.identd´. Thanks to Niels for pointing this out, too. If you want to know more about the identd, please install the package "rfc" that can be found in the documentation series of all SuSE distributions and read rfc1413.txt, to be found in /usr/doc/rfc or /usr/share/doc/rfc (SuSE-7.0).

Thanks, Roman. -- - - | Roman Drahtmüller <draht(a)suse.de> // "Caution: Cape does | SuSE GmbH - Security Phone: // not enable user to fly." | Nürnberg, Germany +49-911-740530 // (Batman Costume warning label) | - - ---------- Forwarded message ---------- _From: Niels Heinen <niels.heinen(a)UBIZEN.COM> _To: BUGTRAQ(a)SECURITYFOCUS.COM Date: Tue, 28 Nov 2000 17:20:11 +0100 Subject: SuSE Linux 6.x 7.0 Ident buffer overflow *************************************************************************** Subject: Ident buffer overflow Platforms: SuSE Linux 6.x 7.0 Risk Level: High Author: Niels Heinen Vendor Status: Notified patches will be available today. *************************************************************************** Impact of the vulnerability: ==================== This advisory details a buffer overflow vulnerability under SuSE Linux that can enable a malicious user to cause Identification Protocol (Ident) handling to crash. Due to the overflow, the system will no longer be able to establish certain connections which use Ident, for example IRC (Internet Relay Chat) connections. If the Ident daemon is not running, users wishing to connect to IRC will not be allowed to make a connection. In the this case the vulnerability could be used in a denial of service attack to keep a person of irc. It's not clear at this present time whether this vulnerability could be exploited in such a way that arbitrary code is executed. If so, this will happen with the privileges of the user "nobody" in a default installation. Who's vulnerable ? ============== This vulnerability has been tested on SuSE version 6.x and version 7.0. Previous versions may also be affected. Further testing will reveal whether other Linux distributions are vulnerable. Technical description: ================ By sending longer than expected strings to the identd port, a remote attacker can crash the daemon. The daemon will also fail to leave any log message given the right length of he string. Seeing the following in the logfile (/var/log/messages) date: suse-machine in.identd[xxx]: s_snprintf(...) = ?: buffer overrun is a clear indication of being attacked by a message length producing log entries. Some other Linux distributions are not vulnerable in the same way, but have to be looked at for suspicious log entries. Another test machine running Red Hat issued here a "Full buffer closing connection" error. Workarounds: =========== If you don't need the Ident, you can keep risk lowest by disabling the ident deamon. This can be done by editing /etc/rc.config. Look for a line like below: START_INDENTD="yes" Change the yes value into no and save the file. After that type as root killall -9 in.identd to stop the ident deamon.

dowloading pictures
by Faessen Jean-Paul 29 Nov '00

29 Nov '00

Hey guys; I use to download a lot of pictures of the Net. As I have yet no CD Rewritable I put some on floppy. Let's say I put picture A on the floppy. After putting it on I delete the picture so it goes to Trash. After the work is done,I empty Trash. I go surfing again,with the necessary downloads. I open my user home directory,I open my floppy and kdf. Then I click "show thumbnails". Weird thing happens as often the old picture A is shown as a thumbnail,but if you open it it's the newly downloaded picture you see. How can a deleted picture reappear again as thumbnail? Is this a bug or do I have a hacker controlling my Trash? Greetings Jean-Paul

Hello, suse-security. i'm sorry to bother you with this question, but i've spent much time with this problem and haven't solved it yet. so, the situation: eth0 is connected to local network (vlan-29) (10.51.29.x) eth1 is connected to internet eth2 is connected to local network (vlan-30, vlan-31) (10.51.30.x and 10.51.31.x) there is a very big lan and just one server connects it to internet. i need to count traffic for all ips in lan (vlan-29,30,31) that goes from server (10.51.29.50 for vlan-29, 10.51.30.10 for vlans-30,31) to users. i count web traffic with squid, but i also need to count icq (we're using socks for it) and mail (everybody have mailboxes on server) traffic. masq enabled only for chosen users (not so many), so i don't need to count ftp, irc traffic. can anyone help me to solve this problem? thanks in advance.

Is there a software tool to manage safely the bandwidth on Linux 7.0, PPc Edition? Ideally, I'd like to control the transmit/receive (www, ftp, mail) of a given IP address. Thanks for any help

Re: [suse-security] How secure is sendmail

I'd say that if you've been using sendmail for a lot of time and know it well, it is as secure as the others (as in, you know how to secure it if needed). I would not recommend using it before a lot of studying (docs, but also "live" discussion on mailing lists): unless you absolutely need some feature only sm has, go with one of the others, especially if you suspect you won't have the time it takes to know sendmail well. Ciao, Rob!

There already is a active #SuSE channel on irc.linux.com. There is also a new channel on the same server #susesecurity. See you there.
