From: secure@conectiva.com.br To: conectiva-updates@papaleguas.conectiva.com.br, linuxlist@securityportal.com, lwn@lwn.net, bugtraq@securityfocus.com Subject: [CLA-2001:406] Conectiva Linux Security Announcement - xinetd Date: Sat, 30 Jun 2001 14:01:51 -0300 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- 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.
