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

OVERVIEW
--------
  This update upgrades Pine from version 4.33 to version 4.50.  Pine
  4.50 includes many bug fixes and new features such as threading
  support and rule pattern enhancements.

  This update also fixes some security issues, in particular a buffer
  overflow when parsing certain "From:" addresses.  A malicious user
  could send a message with a specially crafted "From:" address and
  cause a segmentation fault on the client.  Pine 4.50 fixes this
  vulnerability (CAN-2002-1320) and several others.

SOLUTION
--------
  Users of the EnGarde Professional edition can use the Guardian Digital
  Secure Network to update their systems automatically.

  EnGarde Community users should upgrade to the most recent version
  as outlined in this advisory.  Updates may 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 files

  You must now update the LIDS configuration by executing the command:

    # /usr/sbin/config_lids.pl

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

    # /sbin/lidsadm -S -- +LIDS_GLOBAL

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

    # rpm -Kv files
