Red Hat, Inc. Red Hat Security Advisory



Synopsis: Updated ypserv packages fixes memory leak

Advisory ID: RHSA-2002:223-07

Issue date: 2002-10-08

Updated on: 2002-10-24

Product: Red Hat Linux

Keywords: ypserv memory leak

Cross references:

Obsoletes:

CVE Names: CAN-2002-1232

---------------------------------------------------------------------



1. Topic:



Updated ypserv packages which fix a memory leak are now available for Red

Hat Linux 7.x and 6.2.



2. Relevant releases/architectures:



Red Hat Linux 6.2 - alpha, i386, sparc

Red Hat Linux 7.0 - alpha, i386

Red Hat Linux 7.1 - alpha, i386, ia64

Red Hat Linux 7.2 - i386, ia64

Red Hat Linux 7.3 - i386



3. Problem description:



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 Linux 7.x to ypserv version 2.5 which doesn't

have the memory leak, and updates Red Hat Linux 6.x to a patched version of

ypserv that doesn't have the memory leak.



4. Solution:



Before applying this update, make sure all previously released errata

relevant to your system have been applied.



To update all RPMs for your particular architecture, run:



rpm -Fvh [filenames]



where [filenames] is a list of the RPMs you wish to upgrade. Only those

RPMs which are currently installed will be updated. Those RPMs which are

not installed but included in the list will not be updated. Note that you

can also use wildcards (*.rpm) if your current directory *only* contains the

desired RPMs.



Please note that this update is also available via Red Hat Network. Many

people find this an easier way to apply updates. To use Red Hat Network,

launch the Red Hat Update Agent with the following command:



up2date



This will start an interactive process that will result in the appropriate

RPMs being upgraded on your system.
