1. Problem Summary

    From MandrakeSoft's excellent summary:
    OpenLDAP follows symbolic links when creating files. The default
    location for these files is /usr/tmp, which is a symlink to /tmp,
    which in turn is a world-writable directory.

2. Impact

   Local users can destroy the contents of any file on any mounted
   filesystem.

3. Solution

  Update the packages from our ftp server by running the following command
  for EACH new openldap package (4 total):

  rpm -Fvh ftp_path_to_filename

  Where ftp_path_to_filename are the following:

  ftp://ftp.turbolinux.com/pub/updates/6.0/security/openldap-1.2.10-1.i386.rpm
  ftp://ftp.turbolinux.com/pub/updates/6.0/security/openldap-devel-1.2.10-1.i386.rpm
  ftp://ftp.turbolinux.com/pub/updates/6.0/security/openldap-libs-1.2.10-1.i386.rpm
  ftp://ftp.turbolinux.com/pub/updates/6.0/security/openldap-server-1.2.10-1.i386.rpm

  The source rpm can be downloaded here:

  ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/openldap-1.2.10-1.src.rpm

  **Note: You must rebuild and install the rpms if you choose to download
  and install the srpm.  Simply installing the srpm alone WILL NOT CLOSE
  THE SECURITY HOLE.

  Please verify the md5 checksum of the updates before you install:

  MD5 sum				Package Name
