                    Linux-Mandrake Security Update Advisory
    ________________________________________________________________________

    Package name: exmh
    Date: January 26th, 2001
    Advisory ID: MDKSA-2001:015

    Affected versions: 6.0, 6.1, 7.0, 7.1, 7.2, Corporate Server 1.0.1
    ________________________________________________________________________

    Problem Description:

     All versions of exmh prior to 2.3.1 use the /tmp directory for storing
     temporary files. This was done in an insecure manner as exmh did not
     check to ensure that nobody placed a symlink with the same name in /tmp
     in the meantime and thus was vulnerable to a symlink attack. This
     could lead to a malicious local user being able to overwrite any file
     writable by the user executing exmh. These updated versions of exmh
     now use /tmp/username unless TMPDIR or EXMHTMPDIR is set.
    ________________________________________________________________________

    Please verify the update prior to upgrading to ensure the integrity of
    the downloaded package. You can do this with the command:
      rpm --checksig package.rpm
    You can get the GPG public key of the Linux-Mandrake Security Team at
      http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS
    If you use MandrakeUpdate, the verification of md5 checksum and GPG
    signature is performed automatically for you.

    To upgrade automatically, use MandrakeUpdate.

    If you want to upgrade manually, download the updated package from one
    of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".

    You can download the updates directly from one of the mirror sites
    listed at:

      http://www.linux-mandrake.com/en/ftp.php3.

    Updated packages are available in the "updates/[ver]/RPMS/" directory.
    For example, if you are looking for an updated RPM package for
    Linux-Mandrake 7.2, look for it in "updates/7.2/RPMS/". Updated source
    RPMs are available as well, but you generally do not need to download
    them.

    Please be aware that sometimes it takes the mirrors a few hours to
    update.
