Hello All: I am having a problem trying to get my new kernel image to boot. I have recompiled the kernel for IPTables/NAT support and after I do a make dep clean bzImage, make modules, make bzlilo and make modules_install..I copy the old kernel over to vmlinuz.old and make the new bzImage the vmlinuz and adjust the lilo.conf file accordingly. I then restarted lilo and rebooted...it will get only a little ways before it comes up with "could not mount root", please specify differnt area for root= I have gone over this several times and keep getting the same problem. What step am I missing here? Anyone's help is greatly appreciated. Thanks Traci

PAM - Error

by Boris Kantwerk

Hi List! On my SuSE 6.2 Box (all relevant security patches installed) I tried to change the password for a user. server:~ # passwd bruni passwd: Module is unknown server:~ # cd /var/log server:/var/log # tail warn Oct 30 20:36:32 server passwd[21887]: PAM unable to dlopen(/lib/security/pam_pwcheck.so) Oct 30 20:36:32 server passwd[21887]: PAM [dlerror: /lib/security/pam_pwcheck.so: cannot open shared object file: No such file or directory] Oct 30 20:36:32 server passwd[21887]: PAM adding faulty module: /lib/security/pam_pwcheck.so After re-installing the pam.rpm the same error occured while changing password. Any ideas how solve this problem? Cheers, Boris.

Reqeust for comments

by Christopher Mahmood

Hi all, There's been a request to have attachments in postings stripped before being sent off in the interest of keeping ISPs from blocking posts because of "dangerous content". In this case, it was post a during the recent discussion on (ironically enough) regexes in postfix's body_checks that contained an empty file named AUTOEXEC.BAT, that was sent in order to test a postfix configuration. Personally, I'm all for stripping removing attachments and rejecting posts that consist only of a MIME attachment because they annoy me, but I think I'm in the minority. Of course, we don't have to block all attachments but just the "dangerous" ones. I'd appreciate any thoughts you may have on this but, in the interest of subscribers that aren't interested or don't care, please send them directly to ml-admin(a)suse.com and not the list. Thanks, -- -ckm

Re: [suse-security] SuSE Security Announcement: kernel (SuSE-SA:2001:036)

by Marcin Gryszczuk

Hi List.. As I do not want to have default kernel and I also have not so much compiled inside, I have installed lx_sus22-2.2.19-SuSE-103.i386.rpm So I start to compile it with my previous configuration (before I use also 2.2.19) and during making bzImage I have got following error list: kernel/kernel.o: In function `context_thread': kernel/kernel.o(.text+0xc4): undefined reference to `memset' kernel/kernel.o: In function `flush_scheduled_tasks': kernel/kernel.o(.text+0x308): undefined reference to `memset' kernel/kernel.o: In function `__down': kernel/kernel.o(.text+0x21b4): undefined reference to `memset' kernel/kernel.o: In function `__down_interruptible': kernel/kernel.o(.text+0x2258): undefined reference to `memset' kernel/kernel.o: In function `sys_wait4': kernel/kernel.o(.text+0x8a29): undefined reference to `memset' fs/fs.o(.text+0x3695): more undefined references to `memset' follow make: *** [vmlinux] Error 1 Does anybody have any idea?? I can send the whole kernel config of course, but the same config is OK for previous release of kernel 2.2.19 (without this bug fixed). And I also tried to recompile the previous one (after I got this error on new one) - and it is still OK.. So this looks like some general problem in this kernel source distribution...

One more off-topic comment: Adaptec AHA-2400 IDE Raid supports 4 IDE ATA 100 drives with Raid5 and runs under Linux (SuSE 7.2 and 7.3). I have one 120 GB Raid5 with 4 x 40 GB IDE and 1 cold standby running 3 partitions /boot (ext3), / (reiser) and /data (reiser) and it runs smothly since more than 2 months.

Reiserfs is fine, but you have first to partition the disks, then you define the raid-array and don´t format it, if you plan to use LVM! At this point you leave it as ext2. With LVM you can partition the raid-array. Use yast2 for installation. Yast1 can´t configure raid. >-- >__________________________________________ >J.Andersen -- To unsubscribe, e-mail: suse-security-unsubscribe(a)suse.com For additional commands, e-mail: suse-security-help(a)suse.com

SuSE Security Announcement: squid (SuSE-SA:2001:037)

by Roman Drahtmueller

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: squid Announcement-ID: SuSE-SA:2001:037 Date: Tuesday, Oct 30th 2001 12:30 MEST Affected SuSE versions: 6.3, 6.4, 7.0, 7.1, 7.2, 7.3 Vulnerability Type: remote denial of service Severity (1-10): 4 SuSE default package: no Other affected systems: Systems running the squid proxy server Content of this advisory: 1) security vulnerability resolved: squid 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 squid proxy server can be crashed with a malformed request, resulting in a denial of service attack. After the crash, the squid proxy must be restarted. The weakness can only be triggered from an address that is allowed to send requests, as configured in the squid configuration file. An upgrade to a fixed version of the squid package is the only reasonable countermeasure against the bug. Please download the package for your distribution, verify its integrity according to section 3) of this SuSE Security announcement, then apply the update using the command rpm -Uhv <package.rpm> where <package.rpm> is the filename of the package that you downloaded. NOTE: SuSE Linux distributions come with two different squid packages: One development package and one stable package. The respective package for your installation can be found using the command rpm -qa|grep squid Please download and update only the package that is installed on your system as determined by the version of the package installed. Both packages for your distribution are listed below. SPECIAL INSTALL INSTRUCTIONS: The squid proxy has to be restarted in order for the fix to become effective. Use the command rcsquid restart after successful installation of the upgrade to do this. Please note that the start of the squid daemon can use several seconds so that the daemon refuses to accept connections during that time. i386 Intel Platform: SuSE-7.3

______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - openssh After stabilizing the openssh package, updates for the distributions 6.4-7.2 are currently being prepared. The update packages fix a security problem related to the recently discovered problems with source ip based access restrictions in a user's ~/.ssh/authorized_keys2 file. The packages will appear shortly on our ftp servers. Please note that packages for the distributions 6.3 and up including 7.0 containing cryptographic software are located on the German ftp server ftp.suse.de, all other packages can be found on ftp.suse.com at the usual location. We will issue a dedicated Security announcement for the openssh package. ______________________________________________________________________________ 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. Only SuSE's security annoucements are sent to this list. To subscribe, send an email to <suse-security-announce-subscribe(a)suse.com>.
