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

  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 is a cross-site scripting vulnerability in webalizer which can
  allow an attacker to exploit a victim by embedding malicious HTML tags
  in webalizer-generated reports.


DETAIL
- ------
  This update fixes the aforementioned cross-site scripting
  vulnerability reported by Magnux Software.  This updated version also
  fixes a date calculation overflow error and enables DNS resolution
  provided it is enabled in the webalizer configuration file.


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

  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 filename
