SuSE: Updated kdelibs packages fix remote file creation

The kdelibs3 (kdelibs for SLES7 based products) package is a core package for the K desktop environment (KDE). The URI handler of the kdelibs3 and kdelibs class library contains a flaw which allows remote attackers to create arbitrary files as the user utilizing the kdelibs3/kdelibs package. Affected are applications which use the kdelibs3/kdelibs URI handler such as Konqueror or Kmail. Fixed packages are available from ftp.suse.com.

2)  Pending vulnerabilities in SUSE Distributions and Workarounds:

    - rsync
    rsync prior to version 2.6.1 does not properly sanitize paths
    when running as read/write daemon without chroot. New update packages
    are available on our ftp servers which fix this problem.

    - film
    The film program creates temporary files in an insecure way. New
    update packages are available on our ftp servers.

    - apache/mod_ssl
    A buffer overflow in a uuencode function of mod_ssl has been fixed as
    well as various minor bugs (CAN-2003-0987, CAN-2003-0020, CAN-2004-0174
    and CAN-2003-0993). New packages are currently being tested and will
    soon be available on our ftp servers.

______________________________________________________________________________

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 un-installed 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 top-level 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@suse.com
        -   general/linux/SUSE security discussion. 
            All SUSE security announcements are sent to this list.
            To subscribe, send an email to

    suse-security-announce@suse.com
        -   SUSE's announce-only mailing list.
            Only SUSE's security announcements are sent to this list.
            To subscribe, send an email to
                .
