                Mandrake Linux Security Update Advisory

Package name:           ypserv
Advisory ID:            MDKSA-2003:072
Date:                   June 27th, 2003

Affected versions:	8.2, 9.0, Corporate Server 2.1

Problem Description:

 A vulnerability was found in versions of ypserv prior to version 2.7.
 If a malicious client were to query ypserv via TCP and subsequently
 ignore the server's response, ypserv will block attempting to send
 the reply.  The result is that ypserv will fail to respond to other
 client requests.  ypserv 2.7 and above have been altered to fork a
 child for each client request, which prevents any one request from
 causing the server to block.
