+------------------------------------------------------------------------+
  EnGarde Secure Linux is an enterprise class Linux platform engineered
  to enable corporations to quickly and cost-effectively build a complete
  and secure Internet presence while preventing Internet threats.
OVERVIEW
- --------
  There is a heap corruption vulnerability in sudo which may allow an
  attacker to execute arbitrary commands.
  Please note that this is the same vulnerability addressed in
  ESA-20020429-010.  Due to an error, this bug was never fixed in later
  EnGarde versions.
  The impact of this vulnerability is minimal, as only trusted users
  are permitted to access the sudo binary.
  Guardian Digital products affected by this issue include:
    EnGarde Secure Community 2
    EnGarde Secure Professional v1.2
    EnGarde Secure Professional v1.5
  It is recommended that all users apply this update as soon as possible.
SOLUTION
- --------
  Guardian Digital Secure Network subscribers may automatically update
  affected systems by accessing their account from within the Guardian
  Digital WebTool.

    EnGarde Secure Community v1.0.1
    EnGarde Secure Community 2

+------------------------------------------------------------------------+
  EnGarde Secure Linux is an enterprise class Linux platform engineered
  to enable corporations to quickly and cost-effectively build a complete
  and secure Internet presence while preventing Internet threats.
OVERVIEW
- --------
  This kernel update fixes several bugs and vulnerabilities.  A summary
  of the changes from the last kernel update are below.
    * Systems with more then one swap partition defined could OOPS when
      "swapoff -a" was run.
    * This update improves the kernel module loader vulnerability fix
      (CAN-2003-0127) initially fixed in ESA-20030318-009.
    * Using specially selected forged source addresses, a remote attacker
      can cause a very large number of collisions in the kernel's
      networking hash tables, resulting in a denial of service attack.
      The Common Vulnerabilities and Exposures project (cve.mitre.org/) has
      assigned the name CAN-2003-0244 to this issue.
    * The "ioperm" system call does not properly restrict privileges,
      potentially allowing an unprivileged local user access to the I/O
      ports on the system.
      The Common Vulnerabilities and Exposures project (cve.mitre.org/) has
      assigned the name CAN-2003-0246 to this issue.
  Guardian Digital products affected by these issues include:
    EnGarde Secure Community 2
    EnGarde Secure Professional v1.5
  It is recommended that all users apply this update as soon as possible.
