| Summary: chunk handling overflow vulnerability                         |
+------------------------------------------------------------------------+

  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 vulnerability in the Apache web server which may allow an
  attacker to launch a Denial of Service attack against Apache.  In some
  cases this vulnerability may be used to gain elevated privileges but it
  is not believed to be exploitable on EnGarde at this time.

  For more information on this vulnerability please see CERT advisory
  CA-2002-17 at  http://www.cert.org/advisories/CA-2002-17.html.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
  assigned the name CAN-2002-0392 to this issue.

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 file

  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 file
