Vulnerability Assessment Details

RHSA-2003-201: ypserv

Vulnerability Assessment Summary
Check for the version of the ypserv packages

Detailed Explanation for this Vulnerability Assessment


Updated ypserv packages fixing a denial of service vulnerability are now
available.

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.
