RHEL 2.1 : ypserv (RHSA-2002:224)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated ypserv packages which fix a memory leak are now available for
Red Hat Linux Advanced Server.

[Updated 08 Jan 2003] Added fixed packages for the Itanium (IA64)
architecture.

[Updated 06 Feb 2003] Added fixed packages for Advanced Workstation
2.1

ypserv is an NIS authentication server. ypserv versions before 2.5
contain a memory leak that can be triggered remotely.

When someone requests a map that doesn't exist, a previous mapname may
be leaked. This happens, for instance, if you run 'ypmatch foo
aaaaaaaaaaaaaaaaaaaa'. Repeated runs will result in the yp server
using more and more memory, and running more slowly. It could also
result in ypserv being killed due to the system being out of memory.

This errata updates Red Hat Advanced Server 2.1 to a patched version
of ypserv that doesn't have the memory leak.
