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

    The eMail access daemons impad(8), ipop2d(8) and ipop3d(8) of SuSE 6.1
    are vulnerable to several buffer overflows. Due to a misconfiguration
    these vulnerbilities could be triggered remotely after a user had been
    authenticated.

    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.

2)  Pending vulnerabilities in SuSE Distributions and Workarounds:

    - joe (configuration file vulnerability): The problem has been reported
      on multiple security-related mailing lists. We are about to provide
      fixed packages.

    - The game spaceboom (SVGA shoot'em up) has been found vulnerable to
      multiple vulnerabilities. As a reaction to these bugs, the spaceboom
      game has been dropped from the distribution. We recommend to deinstall
      the game from our 6.x and 7.x distribution by using the command
      `rpm -e spaceŽ, or to remove the suid bit from the file
      /usr/games/SpaceBoom/SpaceBoom using the command
      `chmod -s /usr/games/SpaceBoom/SpaceBoomŽ.
      (Note: removing the suid bit prevents the game from being used by
      non-root users and from being reinstalled after removal.)

    - We are in the process of preparing update packages for the man package
      which has been found vulnerable to a commandline format string bug.
      The man command is installed suid man on SuSE systems. When exploited,
      the bug can be used to install a different man binary to introduce a
      trojan into the system. As an interim workaround, we recommend to
      `chmod -s /usr/bin/manŽ and ignore the warnings and errors when
      viewing manpages.

    - The file browser MidnightCommander (mc) is vulnerable to unwanted
      program execution. Updates are currently being built.

    - A new nkitb/nkitserv package will be availabe soon. This update adresses
      bugs in timed, in.ftpd (and rwhod).

    - A vulnerbility, that exists in the eperl package for SuSE 6.1-7.1 are
      currently being built.
