______________________________________________________________________________

1) problem description, brief discussion

    Stefan Esser reported various bugs within the Cyrus IMAP Server.
    These include buffer overflows and out-of-bounds memory access
    which could allow remote attackers to execute arbitrary commands
    as root. The bugs occur in the pre-authentication phase, therefore
    an update is strongly recommended.
    

2) solution/workaround

    There is no temporary workaround except shutting down the IMAP server.
    
   
3) special instructions and notes

    After successfully updating the cyrus-imapd package you have to issue
    the following command as root:

      /sbin/rccyrus restart

      
4) package location and checksums

    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 for installation from the maintenance web.

5)  Pending vulnerabilities in SUSE Distributions and Workarounds:

    - suidperl
      SUSE LINUX 9.2 follows the new upstream policy to install
      /usr/bin/suidperl as hardlink to /usr/bin/perl. In previous perl
      versions it used to be a hardlink to /usr/bin/sperl*. Therefore one
      must not set a setuid bit on /usr/bin/suidperl as suggested in the
      RPM package description of perl. Set the bit on /usr/bin/sperl5.8.5
      instead if you really need the suid feature. Also check your
      /etc/permissions.local file for references of /usr/bin/suidperl if
      you where upgrading from previous SUSE LINUX releases.
      
      SUSE Linux is not affected by this problem in the default
      installation, only if the administrator added the s-bit to
      suidperl.

    - putty
      The SUSE LINUX distribution comes with putty a Windows-based SSH and
      Telnet client. This client is vulnerable to a buffer overflow that
      can be exploited by a malicious SSH server to execute arbitrary code
      remotely. Putty is just included on the CDs/DVDs and is not installed
      on the Linux system.
      Upcoming distributions will have this vulnerability fixed.

______________________________________________________________________________

6)  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@...e.de),
       the checksums show proof of the authenticity of the package.
       We recommend against subscribing to security lists that cause the
       e-mail 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
       file name 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@...e.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 .
