        Date: Tuesday, April 10th, 2001 15.23 MEST
        Affected SuSE versions: 6.1, 6.2, 6.3, 6.4, 7.0, 7.1
        Vulnerability Type: local privilege escalation
        Severity (1-10): 5
        SuSE default package: yes
        Other affected systems: all system using vim/gvim

        Content of this advisory:
        1) security vulnerability resolved: vim/gvim
           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 text editor vim, Vi IMproved, was found vulnerable to two security
    bugs.
    1.) a tmp race condition
    2.) vim commands in regular files will be executed if the status line
        of vim is enabled in vimrc
    Both vulnerabilities could be used to gain unauthorized access to more
    privileges.

    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:

    - 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.

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

    - NEdit a GUI-style text editor needs an update due to a tmp race
      condition. The source code is currently being reviewed and new
      RPMs will be available within the next days.
