Security Advisory Updated ypserv packages fixes memory leak

Advisory: RHSA-2002:223-07
Type: Security Advisory
Severity: N/A
Issued on: 2002-10-08
Last updated on: 2002-10-24
Affected Products: Red Hat Linux 6.2
Red Hat Linux 7.0
Red Hat Linux 7.1
Red Hat Linux 7.2
Red Hat Linux 7.3
CVEs (cve.mitre.org): CVE-2002-1232

Details

Updated ypserv packages which fix a memory leak are now available for Red
Hat Linux 7.x and 6.2.

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.


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.
