Redhat : Updated ypserv packages fixes memory leak



 ---------------------------------------------------------------------
                    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: =20
 Obsoletes:        =20
 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.
