RHEL 2.1 : ypserv (RHSA-2002:224)

medium Nessus Plugin ID 12329

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.

Solution

Update the affected ypserv package.
