RHBA-2004:021 - Bug Fix Advisory
Synopsis
Updated ypbind packages prevent core dumps
Type/Severity
Bug Fix Advisory
Topic
Updated ypbind packages prevent a problem where ypbind could dump core when
verifying active servers.
Description
The ypbind package contains the ypbind daemon, which binds NIS clients to
an NIS domain.
Every 20 seconds ypbind "pings" all NIS servers marked as active. During
this server verification, ypbind could dump core from referencing through a
NULL pointer. A check was added to ensure this did not happen.
Users of ypbind should install this updated package, which is not
vulnerable to this issue.
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.
If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate. The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:
