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

    The ePerl program is a interpreter for the Embedded Perl 5 Language.
    It's main purpose is to serve as Webserver scripting language for dynamic
    HTML page programming. Besides this it could also serve as a standalone
    Unix filter.
    Fumitoshi Ukai and Denis Barbier have found several potential buffer
    overflows, which could lead to local privilege escalation if installed
    setuid (note: it's not installed setuid per default) or to remote
    compromise.

    There is currently no efficient measure against the security problems
    in the eperl perl interpreter other than not using or updating it.
    SuSE provides update packages for the defective software.

    SuSE Linux version before 6.3 don't include the eperl package.

    Download the update package from locations described 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:

    - 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/man´ 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.

    - Two bugs were found in the text editor vim. These bugs are currently
      being fixed.

    - A bufferoverflow in sudo was discovered and fixed RPMs will be
      available as soon as possible. A exploit was not made public until
      now.
