| Summary: ELF parsing routine buffer 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, e-commerce, and integrated open source
  security tools.

OVERVIEW
- --------
  There is a buffer overflow vulnerability in the 'file' command's ELF
  parsing routines which can allow an attacker to exploit a victim by
  tricking them into running 'file' on a specially crafted binary.

  The Common Vulnerabilities and Exposures project (cve.mitre.org) has
  assigned the name CAN-2003-0102 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 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

UPDATED PACKAGES
- ----------------
  These updated packages are for EnGarde Secure Linux Community
  Edition.

      MD5 Sum: eda42700a8f5b7d2e43c1c5438d50fe9
