-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: man Announcement-ID: SuSE-SA:2001:019 Date: Tuesday, May 29th 2001 20:30 MEST Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0, 7.1 Vulnerability Type: local privilege escalation Severity (1-10): 4 SuSE default package: yes Other affected systems: most linux systems shipping the mandb package Content of this advisory: 1) security vulnerability resolved: man 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 vulnerabilities have been found in the man package that is installed by default in all SuSE Linux distributions. The first error is a format string bug in the error handling routine of the man command that can allow a local attacker to gain the privileges of the user "man" on SuSE Linux systems (the man command in /usr/bin is installed setuid man). After getting write access to the /usr/bin/man binary, an attacker can place a cuckook's egg into the executable, waiting for root to view manpages. The second problem is a segmentation fault that can be caused by the options "-S ::: foo" to the man command. On other Linux distributions, this problem has been found exploitable. On SuSE and Debian systems, the code responsible for the bug is different from the one found in other distributions and is not exploitable. We consider the existence of this bug a beauty flaw that will be fixed in future releases of the SuSE Linux distribution, but the fix was not included in the man packages that can be found on our ftp server. Since the error() format string bug was discovered earlier than we announced that the SuSE Linux distributions 6.0, 6.1 and 6.2 will be discontinued, we also provide fixed packages for the said distributions for the i386 Intel architecture. We strongly encourage our usership to upgrade their systems to a newer distribution. Both bugs are fixed in the upcoming release of SuSE Linux 7.2. A temporary workaround (as discussed in earlier SuSE security announcements) is to remove the setuid-bit of the /usr/bin/man file. This will cause errors to be printed when viewing a manpage, because the formatted manpages can't be saved to the /var/cache/man directories any longer. The sideeffects of this workaround are of mostly cosmetical nature on fast hardware. If you changed the file modes of the man command binary using the command chmod 755 /usr/bin/man , then please also change the occurrences of the same path in the files /etc/permissions*, provided you have set the variable CHECK_PERMISSIONS to "set" in /etc/rc.config. Download the update package from locations described below and check the authenticity of the rpm package file using a method as described in section 3) of this security announcement. Use the command `rpm -Uhv file.rpm' to apply the update. In some rare cases, the older man package contains files that conflict with the new version. This should not be considered a problem in this particular case of the man packge; use the options "--nodeps --force" to override. i386 Intel Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/i386/update/7.1/a1/man-2.3.10d69s-190.i386.rpm bc914ab44fcdeb2fa809176d2b807bea source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/man-2.3.10d69s-190.src.rpm 96dfa2df00ae4a1045c6d038bd02290b SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/man-2.3.10d69s-194.i386.rpm 533fa405f82ef5bbcfb4b4a6c188d0da source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/man-2.3.10d69s-194.src.rpm b935e02d444a613beccec50db65c1cf7 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/a1/man-2.3.10d69s-191.i386.rpm a7cd2aa52a72f739d7c0cac5073f546b source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/man-2.3.10d69s-191.src.rpm e9fd012fbea95c2787de0ee0612da8ce SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/a1/man-2.3.10d69s-191.i386.rpm 807b23473f0813c9c6385d08cc55b698 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/man-2.3.10d69s-191.src.rpm 0ff51500ef8914870cb1785ae3b999b6 SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/a1/man-2.3.10d69i-19.i386.rpm edbbe4c94b18802dc23a823d55d59761 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/man-2.3.10d69i-19.src.rpm eeeed80772476bb306d256e48ad99f95 SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/a1/man-2.3.10-85.i386.rpm 775db984e6129f10ede2b091bf725f0d source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/man-2.3.10-85.src.rpm 5c4b93a1cf941adeb853bff9263ca3a5 Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/a1/man-2.3.10d69s-182.sparc.rpm 39e097e929dbf4ca7626d5c7dcaf4980 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/man-2.3.10d69s-182.src.rpm df6900385722e5a7ddae18338eb0ef4c SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/a1/man-2.3.10d69s-182.sparc.rpm 6c3bda62c576bd92ff7b741a3124e64e source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/man-2.3.10d69s-182.src.rpm c42b095b229f6b4c45bf7814ae0e1498 AXP Alpha Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/a1/man-2.3.10d69s-194.alpha.rpm 3d83a75ff11426bc56fd9663bccee9be source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/man-2.3.10d69s-194.src.rpm 2033a16bc31ec5d81136eabf2508fd6d SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/a1/man-2.3.10d69s-191.alpha.rpm f1ee85f46386298748bdb3d76d69e9f2 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/man-2.3.10d69s-191.src.rpm 82792838d464a1fbb14b2c5d79f4d064 SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/a1/man-2.3.10d69s-190.alpha.rpm 5334e0f9efe1de48d7905166ced83c1b source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/man-2.3.10d69s-190.src.rpm 43992649e6ab51000bed5ac4e2f8fcae PPC Power PC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/a1/man-2.3.10d69s-162.ppc.rpm 5bff5425484c5076023235b3779f22c6 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/man-2.3.10d69s-162.src.rpm 5caba422258827b139e21f6dab7f9b39 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/a1/man-2.3.10d69s-162.ppc.rpm 832b8078f1c6b2d8d6edae98d26c3d44 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/man-2.3.10d69s-162.src.rpm 4d5647b6276fb6d641410e7eddc106f9 SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/a1/man-2.3.10d69s-163.ppc.rpm 13afa53aacaa939fd1b9dd509d995c2d source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/man-2.3.10d69s-163.src.rpm 2ffd94df5356669d89c1490a326c205d ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - netscape Netscape before Version 4.77 contains a bug that allows a remote attacker to store JavaScript code in the comment filed of GIF files that are contained in a viewed page. This code can be executed. Update packages for the SuSE Linux distributions 6.3, 6.4, 7.0 and 7.1 can be found on our ftp server at ftp://ftp.suse.com/pub/suse/i386/update/7.1/xap1/netscape-4.77-21.i386.rpm 1e2de825b3386d80a3731760b9e7f323 ftp://ftp.suse.com/pub/suse/i386/update/7.0/xap1/netscape-4.77-21.i386.rpm ftp://ftp.suse.com/pub/suse/i386/update/6.4/xap1/netscape-4.77-21.i386.rpm ftp://ftp.suse.com/pub/suse/i386/update/6.3/xap1/netscape-4.77-21.i386.rpm 13f303944c9ac0863591b03c4eb75501 The packages are gpg-signed. See the section above about downloading and verifying rpm packages. The complexity of the netscape browser suggests by nature that more security related problems will be found, we will not issue a dedicated security announcement for the netscape package any more. Security- inclined users may please see the future security announcements in section 2) for information about security related problems with the netscape package. - gpg/gnupg The gpg update package that can be found on our ftp server upgrade your installation of gpg to the version 1.0.5. We have experienced stability problems when the turkish locale was used. We recommened our users to wait for the official SuSE Security Announcement about gpg/gnupg before performing the upgrade since we expect more changes to the package. - pine Most of the supported distributions have pine update packages in the update area of the ftp server that update the pine package to version 4.33. Many vulnerabilities have been found in versions before 4.33, and it is recommended to perform the upgrade. Please note that not all packages have been built yet. See the update directory for your distribution (like i386/update/7.0/n1) for pine-4.33 packages. - dqs dex(a)raza-mexicana.org has found an exploitable buffer overflow bug in the dsh program from the dqs package on SuSE Linux distributions. To workaround the problem, do "chmod -s /usr/bin/dsh" and change the files /etc/permissions* to reflect the change. If you do not need the dqs package, then deinstall it (rpm -e dqs). We are working on update packages that fix the problem. - samba Insecure temporary file handling is the cause for a new samba version 2.0.9 that can be found as rpm packages in the n1/ directory of your distribution. It is recommended to install the update package if your users have local shell access to your samba server (this bug is not remotely exploitable). We are currently investigating some oddity in the behaviour of the samba package and will send a security announcement as soon as we have clarified the problems. The problems were present in earlier releases/versions of the samba package as well. By consequence, the installation of the update package is of low risk for the functionality of your system. ______________________________________________________________________________ 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 --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.

SuSE Security Announcement: kernel (SuSE-SA:2001:18)

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: kernel Announcement-ID: SuSE-SA:2001:18 Date: Thursday, May 17th, 2000 16:40 MET Affected SuSE versions: (6.1, 6.2), 6.3, 6.4, 7.0, 7.1 Vulnerability Type: local root compromise Severity (1-10): 7 SuSE default package: yes Other affected systems: All Linux systems using a v2.2 kernel Content of this advisory: 1) security vulnerability resolved: kernel Problem, Workaround, Recommended solution, Instructions, Notes, Verification 2) Acknowledgements 3) standard appendix (further information) ______________________________________________________________________________ 1) The Problem, Workaround, Recommended solution, Instructions, Notes, Verification The Problem: The SuSE Linux kernel is a standard kernel, enhanced with a set of additional drivers and other improvements, to suit the end-user's demand for a great variety of drivers for all kind of hardware. Multiple security vulnerabilities have been found in all Linux kernels of version 2.2 before version 2.2.19. Most of the found errors allow a local attacker to gain root privileges. None of the found errors in the v2.2 linux kernel make it possible for a remote attacker to gain access to the system or to elevate privileges from the outside of the system. Thanks to Alan Cox, a summary of these errors can be found at http://www.linux.org.uk/VERSION/relnotes.2219.html . One of the numerous features in the SuSE Linux kernels is support for reiserfs, a fast, stable logging filesystem. In addition to the bugs listed at www.linux.org.uk, the SuSE Linux kernel contains a fix for a race condition between mmap(2) and write(2) in reiserfs that can expose raw data from the disk to an unprivileged user (this problem affected the ufs and ext2fs drivers in FreeBSD systems, see FreeBSD-SA-01:30.ufs-ext2fs at http://www.freebsd.org/security/) Please see the acknowledgement section 2) below for credits on hunting these bugs and fixing them. Workarounds: In order to solve the security problems, it is recommended to update the kernel to version 2.2.19. Some problems (ptrace race) can be circumvented by removing all suid and sgid bits from all binaries in the system. Since this does not help against the other errors, there is no appropriate temporary workaround against all of the known problems except for locking out users with shell access. Advanced Linux users may decide to compile and install the 2.2.19 kernel themselves by hand. This requires some experience on behalf of the administrator and may not be all satisfying because the standard 2.2.19 kernel does not contain some of the drivers that are included in the SuSE kernel (ppp over ethernet, hardware health monitoring (SMBus), reiserfs, graphics hardware acceleration modules (DRI), ...). Recommended solution: SuSE have chosen to provide update packages for the supported distributions to the newest kernels instead of supplying patched update kernel packages of the same kernel version in order to avoid confusion about whether a vulnerable version of a kernel is installed on a system or not. In addition to the clarifying effect of a visible new kernel version that is known to have all publically known security problems fixed, SAP LinuxLab (http://www.sap.com/linux/) have certified this release of the SuSE-enhanced Linux kernel version 2.2.19 with respect to stability and performance. We expect that our usership will benefit from this achievement. Currently, only kernel update packages for the Intel i386 distributions are available. The other supported architectures will have their kernel updates in their respective update directories on our ftp server. The SuSE Linux distribution 6.0 was shipped with a kernel of version 2.0. All of the SuSE Linux distributions 6.1, 6.2, 6.3, 6.4, 7.0 and 7.1 are ready for a kernel of version 2.2.19. However, since update support for the SuSE Linux distributions 6.0, 6.1 and 6.2 has been discontinued, we strongly encourage all users of these distributions to update their systems to a newer version of the SuSE Linux distribution. Please know that the full distribution can be installed from our ftp server or one of its mirrors. Experienced Linux users may choose to update their kernels by hand to the latest version 2.2.19. Step-By-Step Installation Instructions: The kernel of a Linux/Un*x system is the most critical component with relation to stability, reliability and security. By consequence, an update of that component requires some care and full attention to succeed. The following paragraphs will guide you through the installation process in a step-by-step fashion. The character sequence "****" marks the beginning of a new paragraph. In some cases, you decide if the paragraph is needed for you or not. Please read through all of the steps down to the end. All of the commands that need to be executed are required to be run as the superuser (root). Each step relies on the steps before to be successfully completed. **** Step 1: Determine the needed RPM package Use the command rpm -qf `awk -F= '/image/{print $2}' < /etc/lilo.conf` to find the name of the kernel RPM package that is installed on your system. Get the respective kernel RPM package from the following location: <a href="ftp://ftp.suse.com/pub/suse/i386/update/<DIST">ftp://ftp.suse.com/pub/suse/i386/update/<DIST</a>>/kernel/2.2.19/ where <DIST> is the distribution version of your system (one out of 6.3, 6.4, 7.0 or 7.1). Most installations are likely to run a k_deflt kernel. To verify the integrity of the files that you need to download, see the section "Verification" near the end of this announcement. In SuSE-6.3 distributions, the above command can produce inconclusive results. This is caused by a different kernel installation procedure in this version of the SuSE Linux distribution. To select your kernel type, choose from the following options: k_eide - should be used for "exotic" IDE chipsets, mostly found on additional IDE interface adapters to PCI or ISA bus systems. k_laptop - should be used for laptops. This kernel has APM support configured. k_i386 - a kernel that should run on most i386 processors. Use this kernel package if the k_pentiu kernel will not boot. k_smp - kernel for multiprocessor systems (SMP) k_pentiu - the standard kernel. It should run on most systems. In the case that you have a self-compiled kernel running on your system, please note that most kernels for the newer distributions have APM configured. This obsoletes the need for a particular laptop kernel. k_deflt (after SuSE-6.3) should do on most modern hardware. **** Step 2: SuSE-6.3 special If you have a SuSE-6.3 system, continue to read this paragraph, otherwise jump to Step 3. In SuSE Linux version 6.3, the kernel and the kernel modules are packaged in two different packages. Both packages must be downloaded and installed. On SMP systems, the packages kernmods (-> kernmod-SMP) and k_smp are needed. On single processor systems, get the kernmod package plus the package as determined by the description in Step 1. **** Step 3: Installation of the RPM package Install the rpm package using the command rpm -Uhv <K_FILE.RPM> where <K_FILE.RPM> is the rpm package you downloaded in Step 1 (for 6.3 also Step 2, two packages!). If the RPM command complains about conflicting files or unfulfilled dependencies, use the options "--nodeps" and "--force". In this case there is no risk for the consistency of the packages on your system. **** Step 4: aic7xxx If you use an Adaptec aic7xxx SCSI host adapter, continue to read this paragraph, otherwise jump to Step 5. The new kernel comes with two versions for the Adaptec aic7xxx driver. If you have such a card, you should see the driver listed in the output from the command lsmod or you should see the adapter in the output of the command lspci The new driver is known to work reliably. However, if you encounter any problems with CDROM drives or other removeable devices (CD-RW drives, tapes, etc) after this kernel upgrade, then you should try to use the old driver which is called aic7xxx_old instead of aic7xxx. If you decide to make this change, then the steps 6 and 7 are mandatory for the update to succeed, regardless if you get back to this paragraph after your first reboot or not. To use the old driver, please use your favourite editor to edit the file /etc/rc.config. Change aic7xxx into aic7xxx_old at the line that starts with INITRD_MODULES. You should find it near the top of the file. Do not forget to save your changes. Then go to Steps 6 and 7. If you want to use the new driver, then do not change anything. **** Step 5: LVM If you use LVM, then continue to read this paragraph, otherwise jump to Step 6. If you use LVM (Logical Volume Manager) in your installation of SuSE Linux, then you need the updated lvm package from the kernel/2.2.19/ directory for your distribution as well. The package contains the userspace utilities to manage the Logical Volume Manager driver. An update package is needed because the LVM data format/structure on disk has changed with the new version of the LVM kernel driver. Install the package as usual using the command rpm -Uhv lvm-0.9.1_beta4-12.i386.rpm Be sure you have downloaded the package for the explicit version of your SuSE Linux Installation. The package names are identical for all distribution versions. WARNING: After the first boot with the new kernel you will not be able to downgrade to older versions of LVM any more. **** Step 6: initrd Upon kernel boot (after lilo runs), the kernel needs to use the drivers for the device (disk/raid) where the root filesystem is located. If this driver is not compiled into the kernel, it is supplied as a kernel module that must be loaded _before_ the root filesystem is mounted. This is done using a ramdisk that is loaded along with the kernel by lilo (See next Step). This ramdisk, called "initrd", must be generated using the command mk_initrd The modules as configured in the variable INITRD_MODULES from /etc/rc.config (See Step 4) are being added to the initrd. Without the "mk_initrd"-call your system might not boot any more. **** Step 7: lilo lilo is responsible for loading the kernel image and the initrd ramdisk image into the system and for transferring control over the system to the kernel. Therefore, a proper installation of the bootloader (by calling the program lilo) is essential for the system to boot (!). Manually changed settings in /etc/lilo.conf require the admin to make sure that /boot/vmlinuz is listed in the first "image" line in that file. Verify that the line starting with initrd= is set to initrd=/boot/initrd Execute lilo and you should see your label in an output like Added linux * Every other output should be considered an error and requires attention. If your system managed to reboot before the upgrade, you should not see any additional output from lilo at this stage. **** Step 8: SuSE-7.0 special If you have a SuSE Linux 7.0 distribution, then continue to read this paragraph, otherwise jump to Step 9. During testing of the 2.2.19-SuSE Linux kernel, we have found an error in the glibc (shlibs) package of the SuSE Linux 7.0 distribution. The error might result in readdir(3) calls to return -EIO to the user program due to incorrect handling of the return value of getdents(2) from the kernel. This bug mostly appears on NFS-mounted filesystems when commands such as tar(1) are used. We have prepared update packages that solve this specific problem. Former security updates are included in this package, of course. Determine which packages you need: See the output of the command rpm -q shlibs libc libd nssv1 It should not be necessary to update a package that is not installed. Select the needed update packages and download them from the following list of URLs ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/shlibs-2.1.3-193.i386.rpm ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/nssv1-2.1.3-193.i386.rpm ftp://ftp.suse.com/pub/suse/i386/update/7.0/d1/libc-2.1.3-193.i386.rpm ftp://ftp.suse.com/pub/suse/i386/update/7.0/d2/libd-2.1.3-193.i386.rpm !!! !!! WARNING: !!! !!! After download and before installation of the glibc packages, the system should be brought to single user mode ("init 1"). If this is not suitable for operational reasons, then please keep the system as calm as at all possible during the update of the shlibs and nssv1 packages. In particular, do not run any shell scripts or any other processes that execute other binaries. Stop the cron and at services, and shut down your MTA. Suspend the execution of active processes by killing them with the -STOP signal and let them resume their work after the installation of the shlibs and nssv1 packages with a -CONT signal. After verifying that the right conditions are in place, install the packages using the command rpm -Fhv nssv*.rpm shlibs*.rpm rpm -Fhv <rest> Afterwards, execute the command ldconfig to update the cache for the dynamic linker. NOTE: updating shared libraries in the running system requires enough space on the root and /usr filesystem to keep both versions of the shared libraries on the disk. The old libraries will be deleted, but the files continue to use diskspace until they are not used by any processes any more. (See Step 9). Similar considerations apply for the the memory consumption of the system. **** Step 9: reboot Reboot your machine for the new kernel to boot and therefore become active. Make sure that all of the above steps have completed successfully. Shutdown and reboot using the command shutdown -r now or init 6 Notes: a) After the upgrade, you might notice kernel messages upon execution of an NFS mount command: silence kernel: nfs warning: mount version older than kernel These messages are complaints that the mount(8) command needs to be upgraded. The mount(8) command is contained in the package "util" ("util-linux" for SuSE-7.1) - we will provide update packages for the "util" ("util-linux" for SuSE-7.1) package. The change is mostly a cosmetic nature and does not have any impact on the security or the stability of the system. b) The kernel sources are contained in the RPM kernel/2.2.19/lx_sus22-2.2.19.SuSE-25.i386.rpm in each distribution update tree. The kernel documentation is in the package kernel/2.2.19/lx_doc22-2.2.19.SuSE-25.i386.rpm and installs to the base path /usr/share/doc/kernel/. c) The directory kernel/misc/ in each distribution tree contains the .config files, the spec and changes file as well as the compilation output for the respective kernel, each in a directory where it belongs to. In addition, the sources for the lvm package can be found in the lvm directory as appropriate. Known problems: * The kernel modules for the cipe and the freeswan packages are not contained in the kernel RPM packages. If you use these packages, then you should wait with the kernel update until the kernel modules for these packages are available, or you could recompile the kernel modules yourself (See section Notes b). Please read the section 2) of the upcoming SuSE security announcements for the location of the cipecb.o and ipsec.o kernel modules. Verification: All RPM packages are gpg-signed using the build(a)suse.de SuSE packaging key that can be found in the toplevel directory of the first CD on SuSE-7.1 and younger, as well as at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de (this key is signed by security(a)suse.de) All files that are needed or referred to in this announcement have their md5 sums listed in the file <a href="ftp://ftp.suse.com/pub/suse/i386/update/<dist">ftp://ftp.suse.com/pub/suse/i386/update/<dist</a>>/kernel/MD5SUMS .

-----BEGIN PGP SIGNED MESSAGE----- As a result of a package rebuild, the package for the SuSE-7.1 Intel i386 distribution is not available under the URL as listed below. The listed package was named "cron-3.0.1-297.i386.rpm". This package also fixed the mentioned problems with the package. We are resending this announcement with the correct pathnames and md5sums. Thank you for your understanding, Roman Drahtmüller. ______________________________________________________________________________ SuSE Security Announcement Package: cron-3.0.1-296 Announcement-ID: SuSE-SA:2001:17 (resent) Date: Tuesday, May 15th, 2001 15:30:00 CEST Affected SuSE versions: 7.1 Vulnerability Type: local privilege escalation Severity (1-10): 7 SuSE default package: yes Other affected systems: All UN*X systems using this package Content of this advisory: 1) security vulnerability resolved: crontab 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 crontab program is running setuser-id root and invokes the editor specified in the EDITOR environment variable, usually vi. If crontab discovers that the format of the edited file is incorrect, it executes the editor again but fails to drop its root privileges before. Therefore it is possible to execute arbitrary commands as root. It has been fixed by properly dropping the privileges before executing the editor. This bug was found by Sebastian Krahmer. A possible temporary workaround is to remove the suid bit of the /usr/bin/crontab program: chmod -s /usr/bin/crontab. If you change the mode, you should also do so in the files /etc/permissions*. A permanent solution for the problem is to update the cron package from our ftp server. 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.

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: sgmltool-1.0.9-266 Announcement-ID: SuSE-SA:2001:16 Date: Friday, May 4th, 14:55:35 CEST 2001 Affected SuSE versions: 6.3, 6.4, 7.0, 7.1 Vulnerability Type: local fileaccess problem Severity (1-10): 2 SuSE default package: yes Other affected systems: All UN*X systems using this package Content of this advisory: 1) security vulnerability resolved: sgmltool 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 sgmltool programs ("sgml2html" and others) are used to convert SGML-files into various other formats. During operation, the underlying SGML perlmodule creates temporary files in an insecure way. This allows attackers to destroy arbitrary files owned by the user who invoked the sgmltool program. The problem has been fixed by creating temporary files with the exclusive (O_EXCL) option upon opening them. 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/sgm1/sgmltool-1.0.9-302.i386.rpm bdedaefb82dc2bb8ff0a522607b80ac3 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.1/zq1/sgmltool-1.0.9-302.src.rpm dc5612aa475c5d6dcaaeee86e6bf985f SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/sgm1/sgmltool-1.0.9-301.i386.rpm 916953307d466d3bd8d26fb0655ce55a source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/sgmltool-1.0.9-301.src.rpm 5e11b85a494e1033ee2a83839cb296fe SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/sgm1/sgmltool-1.0.9-300.i386.rpm a489acc5c3dce4c44915e47b3ee64790 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/sgmltool-1.0.9-300.src.rpm efdb6b08988b689127600a954ebe2e2f SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/sgm1/sgmltool-1.0.9-300.i386.rpm 9c1e5da161b67248935cbc7f485dfd40 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/sgmltool-1.0.9-300.src.rpm a2deae294821e73ed24429636b20ed2a Sparc Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/sparc/update/7.1/sgm1/sgmltool-1.0.9-283.sparc.… b3e0ec269392fb3d77c37cc698f77d16 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.1/zq1/sgmltool-1.0.9-283.src.rpm eb80b6efe08f40139ec181fed7ccc832 SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/sgm1/sgmltool-1.0.9-284.sparc.… 8312ac046de5df7a47008dba32f1a7e8 source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/sgmltool-1.0.9-284.src.rpm a7e48214ae01f4f720240c1204120927 AXP Alpha Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/axp/update/7.0/sgm1/sgmltool-1.0.9-283.alpha.rpm 06348dc4b669098d80bc16a8cc836123 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/7.0/zq1/sgmltool-1.0.9-283.src.rpm c7c7ff5507f7a510d615235323f9f636 SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/sgm1/sgmltool-1.0.9-281.alpha.rpm ee6bb4dd45c90ba716f0d825fba7bbca source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/sgmltool-1.0.9-281.src.rpm 44366d7edcace3448a606aff0c73026f SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/sgm1/sgmltool-1.0.9-281.alpha.rpm 2c2450e3dfdde9066269add9cfb0757b source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/sgmltool-1.0.9-281.src.rpm 66a9d60866a5ebbb2e0682a2056f2528 PPC Power PC Platform: SuSE-7.1 ftp://ftp.suse.com/pub/suse/ppc/update/7.1/sgm1/sgmltool-1.0.9-216.ppc.rpm 01bda0ee0edfa1e1036d27b2bb3de352 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.1/zq1/sgmltool-1.0.9-216.src.rpm 1c6668d3ccc1b27bb3d5a4f84b308323 SuSE-7.0 ftp://ftp.suse.com/pub/suse/ppc/update/7.0/sgm1/sgmltool-1.0.9-216.ppc.rpm e9b7161fe3a10624790ce65d9909165d source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/7.0/zq1/sgmltool-1.0.9-216.src.rpm 15b8204b9378f8e833e6bac263bbacdd SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/sgm1/sgmltool-1.0.9-216.ppc.rpm 6af30c53d022866df5dd69ae053eeeea source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/sgmltool-1.0.9-216.src.rpm 35aa3ab2a86498c5e6ad145c0c7e378a ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - Marcus Meissner (Caldera) found a bug in KDE 2.1.*'s kdesu program which allows attackers to gather private information. This is due to insecure local filehandling by the kdesu program. Please update to the newest packages. - minicom format string vulnerabilities have been found in the minicom package. If /usr/bin/minicom is installed suid, the vulnerability may be exploited to gain elevated privileges. Please note that this is not the case in SuSE distributions. If you decided to make /usr/bin/minicom suid uucp or even suid root, please make sure that you grant access to the execution of minicom to trusted users only. - cfingerd The package has been found vulnerable to a remotely exploitable weakness. SuSE Linux distributions do not ship this version of fingerd. - webmin Insecure handling of temporary files has been found in webmin, a comprehensive administration webinterface. SuSE distributions do not contain the webmin package and therefore are not vulnerable to the found vulnerabilities by default. We urge administrators who use webmin to upgrade to the latest version of webmin available. - gnupg/gpg, openssl Several weaknesses have been found in gnupg/gpg that can reduce the strength of encrypted data. We will provide updates for the gnupg/gpg package. The updates are currently being tested. ______________________________________________________________________________ 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.
