___________________________________________________________________________

1. Problem Summary

   Sendmail, launched with the -bt command-line switch, enters its special
   "address test" mode. Under these conditions, it is vulnerable to a
   segmentation fault which can occur when trying to set a class in ad-
   dress test mode due to a negative array index.

2. Impact

   A user can gain root privileges.

3. Solution

  Update the package from our ftp server by running the following command:

  rpm -Uvh ftp_path_to_filename

  Where ftp_path_to_filename is the following:

  ftp://ftp.turbolinux.com/pub/updates/6.0/security/sendmail-8.11.2-5.i386.rpm

  The source RPM can be downloaded here:

  ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/sendmail-8.11.2-5.src.rpm

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

 Please verify the MD5 checksums of the updates before you install:

  MD5 sum                               Package Name
