7.1-i386-ftp
by Roman Drahtmueller 22 Mar '01

22 Mar '01

Hi together, The 7.1-i386-ftp version is out, finally. We've had problems with some packages before we could release it to the public. The 7.1 ftp version contains some newer packages than the CD version - the security updates have been merged as well as many many bugs have been squished. This time, the ftp version of the distribution is something special: For the first time, there is no seperate German/non-US and a US version any more. The international version contains all crypto packages that usually only the German distribution has. This has been made possible by removing all occurrences of patented cryptographical code and/or substituting it with free code. In the end, it turns out that we can live without commercial code... This particular circumstance leads to an easier update structure of the ftp servers: All 7.1 updates, all distributions, will be available on ftp.suse.com (which is located in Oakland, CA), none on ftp.suse.de (which is in Nürnberg, Germany). Also, not an "official" announcement: Efforts are underway to merge the ftp.suse.de update tree with the ftp.suse.com update tree for the older distributions, too. I'll publically announce it when it is getting time (and this will take some weeks...). 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) | - -

The man command is installed suid man on SuSE systems. When exploited, the bug can be used to install a different man binary to introduce a trojan into the system. As an interim workaround, we recommend to `chmod -s /usr/bin/man´ and ignore the warnings and errors when viewing manpages. - The file browser MidnightCommander (mc) is vulnerable to unwanted program execution.

SuSE Security Announcement: nkitb/nkitserv
by Thomas Biege 22 Mar '01

22 Mar '01

Hi, I send the file with a missing signature.. I'm very sorry. :-\ Damn, I need coffee... -----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: nkitb/nkitserv Announcement-ID: SuSE-SA:2001:07 Date: Thursday, March 22th, 2001 19.06 MEST Affected SuSE versions: 6.1, 6.2, 6.3, 6.4, 7.0, 7.1 Vulnerability Type: remote denial-of-service Severity (1-10): 4 SuSE default package: yes: in.ftpd, no: timed Other affected systems: all system using in.ftpd (OpenBSD port) or timed Content of this advisory: 1) security vulnerability resolved: timed, in.ftpd 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 Two parts of the nkitb/nkitserv package are vulnerable to security related bugs. in.ftpd(8): A one-byte bufferoverflow was discovered in the OpenBSD port of the FTP daemon in.ftpd(8) several weeks ago. This bug could just be triggered by authenticated users, which have write access. This bug is believed to not be exploitable under Linux. However, we prefer to provide a fixed update package to make sure that the daemon is on the safe side. in.ftpd(8) will be invoked by inetd(8) and is activated by default. timed(8): The time server daemon timed(8), which is started at boot time, tries to synchronize the local host time with the time of other machines on the local area network. A bug in timed(8) was reported by the FreeBSD Security Officer, that could be triggered remotely to crash the time server daemon. For SuSE 6.1-6.4 in.ftpd and timed were part of nkitb. Users of SuSE 7.0 need to download the nkitserv package for both in.ftpd and timed. The bug in in.ftpd is fixed in SuSE 7.1, so nkitserv for SuSE 7.1 just includes a new version of timed(8). Download the update package from locations desribed below and install the package with the command `rpm -Uhv file.rpm'. The md5sum for each file is in the line below.

SuSE Security Announcement: nkitb/nkitserv
by Thomas Biege 22 Mar '01

22 Mar '01

______________________________________________________________________________ SuSE Security Announcement Package: nkitb/nkitserv Announcement-ID: SuSE-SA:2001:07 Date: Thursday, March 22th, 2001 19.06 MEST Affected SuSE versions: 6.1, 6.2, 6.3, 6.4, 7.0, 7.1 Vulnerability Type: remote denial-of-service Severity (1-10): 4 SuSE default package: yes: in.ftpd, no: timed Other affected systems: all system using in.ftpd (OpenBSD port) or timed Content of this advisory: 1) security vulnerability resolved: timed, in.ftpd 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 Two parts of the nkitb/nkitserv package are vulnerable to security related bugs. in.ftpd(8): A one-byte bufferoverflow was discovered in the OpenBSD port of the FTP daemon in.ftpd(8) several weeks ago. This bug could just be triggered by authenticated users, which have write access. This bug is believed to not be exploitable under Linux. However, we prefer to provide a fixed update package to make sure that the daemon is on the safe side. in.ftpd(8) will be invoked by inetd(8) and is activated by default. timed(8): The time server daemon timed(8), which is started at boot time, tries to synchronize the local host time with the time of other machines on the local area network. A bug in timed(8) was reported by the FreeBSD Security Officer, that could be triggered remotely to crash the time server daemon. For SuSE 6.1-6.4 in.ftpd and timed were part of nkitb. Users of SuSE 7.0 need to download the nkitserv package for both in.ftpd and timed. The bug in in.ftpd is fixed in SuSE 7.1, so nkitserv for SuSE 7.1 just includes a new version of timed(8). Download the update package from locations desribed below and install the package with the command `rpm -Uhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/n1/nkitserv-2001.3.16-0.i386.rpm c4313f92a36916f0eba0b8837c9c0c81 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/nkitb-2001.3.16-1.src.rpm ec452523fa25c8aed962fbd3349d1f3d SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/n1/nkitserv-2001.3.16-0.i386.rpm 02772824805c6c4293bd1750d7bda6d3 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/nkitb-2001.3.16-1.src.rpm 5d301edc1b1ec9111572815aace33984 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/a1/nkitb-2001.3.16-1.i386.rpm 842dea179cc449c4af25accf0c3f38ec source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/nkitb-2001.3.16-1.src.rpm c099e7c1194b7706100453a89433b59c SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/a1/nkitb-2001.3.16-0.i386.rpm 768a636df4731cd8efd181aa2eaf2e60 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/nkitb-2001.3.16-0.src.rpm b705425c4c3cb70ebf9cd1345c92104a SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/a1/nkitb-2001.3.16-0.i386.rpm cbae31148c79c91a1443f79ee1ba34d3 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/nkitb-2001.3.16-0.src.rpm d287c01d35d00756ecbf8da04556037c SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/a1/nkitb-2001.3.16-0.i386.rpm 5f45ade69a9e8c2756e671c4a6e3522a source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/nkitb-2001.3.16-0.src.rpm 62b969c4e666f3ea71b6ce6b31762718 Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/n1/nkitserv-2001.3.16-0.sparc.… 142329dcae76a1603c0d84836192e357 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/nkitb-2001.3.16-0.src.rpm 5bd9123cecba6ddd42cc965c599f383e SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/n1/nkitserv-2001.3.16-0.sparc.… 07ed33c76c7ae2df5b877003b254944d source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/nkitb-2001.3.16-0.src.rpm 66ba7b71624f636e24e2d628c8f06e81 AXP Alpha Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/n1/nkitserv-2001.3.16-0.alpha.rpm 5fcf177588788eb069bdb69332046d23 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/nkitb-2001.3.16-0.src.rpm c27ed3bf0c293eaa77fe5a8fa960e95d SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/a1/nkitb-2001.3.16-0.alpha.rpm 385fa60c0c216f1d9e61afd52d37df93 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/nkitb-2001.3.16-0.src.rpm 5ba60084740c9be9f89a729e2d21a77c SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/a1/nkitb-2001.3.16-0.alpha.rpm 8a9e207a77e3c7f954e8faa91954f7aa source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/nkitb-2001.3.16-0.src.rpm 53f8a03feacc7fb81b92a726c8e81d21 SuSE-6.1 ftp://ftp.suse.com/pub/suse/axp/update/6.1/a1/nkitb-2001.3.16-0.alpha.rpm 359a3432f73220cecd42ba0b365d5e06 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.1/zq1/nkitb-2001.3.16-0.src.rpm e0ccf6395312f9c33518f5f083c9d51f PPC PowerPC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/n1/nkitserv-2001.3.16-0.ppc.rpm 37bf5a963bc93215084b5634e864479c source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/nkitb-2001.3.16-0.src.rpm c31af637f58d9b43db542657b02bc772 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/n1/nkitserv-2001.3.16-1.ppc.rpm ddc1dcfb94ba90f3cbdf395f89dd3b84 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/nkitb-2001.3.16-1.src.rpm 2fa9c58b871248172285a64107e3be7c SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/a1/nkitb-2001.3.16-0.ppc.rpm 1dc4c831b5f6bd344ab8f511497b3fa5 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/nkitb-2001.3.16-0.src.rpm 5529e5f63e2391ab1669efa0a8c33b57 ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - joe (configuration file vulnerability): The problem has been reported on multiple security-related mailing lists.

The man command is installed suid man on SuSE systems. When exploited, the bug can be used to install a different man binary to introduce a trojan into the system. As an interim workaround, we recommend to `chmod -s /usr/bin/man´ and ignore the warnings and errors when viewing manpages. - The file browser MidnightCommander (mc) is vulnerable to unwanted program execution.

sleep() weaknesses
by Sebastian Krahmer 22 Mar '01

22 Mar '01

hi, I just uploaded paper about remote password guessing (and why sleep(x) is not enough to protect) with help of threads and other tricks. Its avail at www.cs.uni-potsdam.de/homepages/students/linuxer/tad.tar.gz It includes sample-program for high guessing-rates and a benchmark-server if you don't want (can) to use your ISP's pop3d. :) regards, Sebastian
