Categoría:	Red Hat Local Security Checks
Título:	RedHat Security Advisory RHSA-2003:201
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2003:201. The ypserv package contains the Network Information Service (NIS) server. A vulnerability has been discovered in the ypserv NIS server prior to version 2.7. If a malicious client queries ypserv via TCP and subsequently ignores the server's response, ypserv will block attempting to send the reply. This results in ypserv failing to respond to other client requests. Versions 2.7 and above of ypserv have been altered to fork a child for each client request, thus preventing any one request from causing the server to block. Red Hat recommends that users of NIS upgrade to these packages, which contain version 2.8.0 of ypserv and are therefore not vulnerable to this issue. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2003-201.html http://www.linux-nis.org/nis/ypserv/ChangeLog Risk factor : Medium CVSS Score: 5.0
