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.

ADDITIONAL INSTRUCTIONS
 Users of Conectiva Linux version 6.0 or higher may use apt to perform 
 upgrades of RPM packages:
 - add the following line to /etc/apt/sources.list if it is not there yet
   (you may also use linuxconf to do this):

 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)

 - run:                 apt-get update
 - after that, execute: apt-get upgrade
