    CONECTIVA LINUX SECURITY ANNOUNCEMENT 
    - --------------------------------------------------------------------------
    
    PACKAGE   : xinetd
    SUMMARY   : Remote buffer overflow
    DATE      : 2001-06-30 14:00:00
    ID        : CLA-2001:406
    RELEVANT
    RELEASES  : 6.0
    
    - -------------------------------------------------------------------------
    
    DESCRIPTION
     "xinetd" is an alternative to the inetd superserver.
     Sebastian Krahmer from SuSe found an additional vulnerability in the
     xinetd package that was not addressed in the previous announcement.
     Internal string handling functions of xinetd do not properly handle
     length arguments of zero. This can lead to buffer overflows and
     arbitrary remote code execution.
     The xinetd package is not used by default in Conectiva Linux 6.0,
     therefore only users who explicitly changed the configuration of
     their services in order to use xinetd will be vulnerable.
    
    
    SOLUTION
     It is recommended that all xinetd users upgrade their packages. This
     update will restart the service if it is already running.

     rpm [cncbr] ftp://atualizacoes.conectiva.com.br 6.0/conectiva updates
    
    (replace 6.0 with the correct version number if you are not running CL6.0)

     - after that, execute: apt-get upgrade
