    +------------------------------------------------------------------------+
    
      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 are several buffer overflows and broken boundary checks in
      fetchmail.  This update brings fetchmail up to version 6.1.0, fixing
      all known issues.
    
    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.
