+------------------------------------------------------------------------+

  EnGarde Secure Linux is a secure distribution of Linux that
  features improved access control, host and network intrusion
  detection, Web based secure remote management, complete e-commerce
  using AllCommerce, and integrated open source security tools.


OVERVIEW
- --------
  There are some potential vulnerabilities in the most recent xinetd
  package for EnGarde Secure Linux 1.0.1.


DETAIL
- ------
  Solar Designer did an audit of xinetd 2.3.0 and came up with a list
  of potential vulnerabilities.  This release fixes all known
  vulnerabilities as a precautionary measure.  Most of these fixes are
  in the interest of robustness and are not known to be exploitable at
  this time.

  For more information on the results of this audit please refer to
  the AUDIT file in the xinetd-2.3.3.tar.gz tarball (included with
  the source package).


SOLUTION
- --------
  All users should upgrade to the most recent version, as outlined in
  this advisory.

  Guardian Digital recently made available the Guardian Digital Secure
  Update, a means to proactively keep systems secure and manage 
  system software. EnGarde users can automatically update their system
  using the Guardian Digital WebTool secure interface.

  If choosing to manually upgrade this package, updates can be
  obtained from:

    ftp://ftp.engardelinux.org/pub/engarde/stable/updates/
    http://ftp.engardelinux.org/pub/engarde/stable/updates/

  Before upgrading the package, the machine must either:

    a) be booted into a "standard" kernel; or
    b) have LIDS disabled.

  To disable LIDS, execute the command:

    # /sbin/lidsadm -S -- -LIDS_GLOBAL

  To install the updated package, execute the command:

    # rpm -Uvh <filename>

  To re-enable LIDS (if it was disabled), execute the command:

    # /sbin/lidsadm -S -- +LIDS_GLOBAL

  To verify the signature of the updated packages, execute the
command:

    # rpm -Kv <filename>
