______________________________________________________________________________

1)  problem description, brief discussion, solution, upgrade information

    This is the second announcement in the tandem-announcement about
    libz/zlib.
    SuSE Security Announcement SuSE-SA:2002:010 (libz/zlib) has been released
    prior to this announcement (SuSE-SA:2002:011). Please see SuSE-SA:2002:010
    for details on the libz weakness. The two announcements SuSE-SA:2002:010
    and SuSE-SA:2002:011 are being published in quick succession.


    The packages affected by the double-free() libz bug can be devided into
    two categories:

        1) packages that link dynamically against the system-provided
           compression library. These packages get fixed automatically with
           the update of the libz package as described in SuSE-SA:2002:010.
           Please note that the processes will continue to use the old
           version of the libz.so shared library if the have not been
           restarted after the libz package upgrade.

        2) packages that contain the compression library in their own
           source distribution. These packages need an individual bugfix.
           We have prepared update packages for this software that can be
           downloaded from the locations as shown below.


    The following is a list of the packages in category 2):
        gpg
        rsync
        cvs
        rrdtool
        freeamp
        netscape
        vnc
        kernel

    In detail:
        gpg:
            gpg brings its own libz/zlib source. The fixed update packages
            are available on the ftp server. The packages for SuSE Linux
            6.4 and 7.0 are located on ftp.suse.de, all other packages can
            be found on ftp.suse.com.
            The package for SuSE Linux 7.3, Intel i386 platform, is
            currently building and will be available shortly.
        rsync:
            The rsync package brings its own libz/zlib source. In addition
            to the libz/zlib fixes, the rsync package has a number of other
            security related problems fixed: The rsync daemon now properly
            initializes group memberships when it changes to another userID.
            The last security fix in the rsync packages has been corrected
            to improve the reliability of the program.
            The fixed update packages are available on the ftp server.
        cvs:
            The cvs package brings its own libz/zlib source. In addition
            to the libz/zlib fixes, the cvs packages in SuSE Linux 6.4 and
            7.0 contain a fix for a buffer overflow that may be remotely
            exploitable. Versions of the cvs packages later than 7.0 do not
            contain this flaw.
        rrdtool:
            SuSE Linux 7.2 and newer contain the package rrdtool. It brings
            its own source of the libz/zlib compression library. Fixed
            packages are available for download on the ftp server.
        freeamp:
            The freeamp package brings its own libz/zlib source. Fixed
            packages for SuSE Linux 7.1 and 7.0 are available for download.
            The update packages for the newer distributions will follow
            soon without any further announcement.
        netscape:
            New netscape binary packages are expected from netscape.com soon.
            Due to the closed source nature of the software, we depend on
            netscape to fix the package.
        vnc:
            The vnc package brings its own libz/zlib source. We will provide
            fixed packages for our supported products shortly. The
            availiability of these packages will be announced in section 2)
            of the next SuSE Security Announcement.
        kernel:
            The kernel of Linux systems is affected by the libz/zlib double-
            free() problem as well. The routines from the compression library
            are being used by functions that uncompress filesystems loaded
            into ramdisks and other non-security-critical occasions. However,
            the kernel uses the compression library in the ppp layer as well
            as in the freeswan IPSec kernel module.
            We are currently in the process of preparing update packages that
            fix numerous other problems (some of them security related) in
            both the 2.2 and the 2.4 series kernel. The availiability of these
            kernel RPM packages will be announced in a seperate SuSE Security
            Announcement soon.


    Note:
    The openssh package contains binaries that are linked dynamically against
    libz.so. The ssh package, however, links statically against its own
    version of the compression library. This version of libz/zlib is not
    vulnerable to the double-free() problem.


    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.


    i386 Intel Platform:

    SuSE-7.3
    The gpg packages are currently building and will be available on the ftp
    server shortly.

2)  Pending vulnerabilities in SuSE Distributions and Workarounds:

  - The freeamp packages for the newer products will be available
    shortly.
    The gpg package for the Intel i386 platform, distribution SuSE Linux 7.3,
    will be available shortly.
    Update packages for the packages vnc, netscape and the kernel will follow
    later this week. Please carefully read the section 2) in the upcoming
    SuSE Security Announcements.

______________________________________________________________________________

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 
       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@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 
       to verify the signature of the package, where  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@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 .
