        Announcement-ID:        SuSE-SA:2002:005
        Date:                   Saturday, Feb 23st 2002 09:10 MET
        Affected SuSE versions: 7.1, 7.2, 7.3
        Vulnerability Type:     remote privilege escalation
        Severity (1-10):        5
        SuSE default package:   no
        Other affected systems: all systems running CUPS

    Content of this advisory:
        1) security vulnerability resolved: CUPS bufferoverflow in IPP
           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 well known Common Unix Printing System (CUPS) was found vulnerable
    to a buffer overflow in the Internet Printing Protocol (IPP) handling
    code.
    The buffer overflow could be exploited by a remote attacker as long as
    their IP address is allowed to connect to the CUPS server.

    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.

    After updateing the packages run "rclpd restart" as root to start the
    new daemon.

2)  Pending vulnerabilities in SuSE Distributions and Workarounds:

    - squid
      A heap overflow in squid's URL constructing functions is fixed and
      new packages are currently being built.

    - ucd-snmpd
      The UCD snmpd contains various security releated bugs.
      We are currently reviewing the code and available fixes to ensure
      they all get fixed. Patches will be available as soon as possible.
      It is strongly recommended to filter SNMP (TCP and UDP packets
      with destination of port 161) traffic.

    - hanterm/wmtv
      The recently reported vulnerabilities in hanterm and wmtv do not
      affect SuSE installations because they are not installed setuid
      or setgid.

    - cipe
      We are about to prepare kernel update packages that fix a DoS
      problem in the kernel modules for the cipe encrypted tunneling
      software.

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 [email protected]),
       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 "[email protected]" 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 .
