RHSA-2003:207 - Security Advisory

Topic

Updated nfs-utils packages are available that fix a remotely exploitable
Denial of Service vulnerability.

Description

The nfs-utils package provides a daemon for the kernel NFS server and
related tools.

Janusz Niewiadomski found a buffer overflow bug in nfs-utils version 1.0.3
and earlier. This bug could be exploited by an attacker, causing a remote
Denial of Service (crash). It is not believed that this bug could lead to
remote arbitrary code execution.

Users are advised to update to these erratum packages, which contain a
backported security patch supplied by the nfs-utils maintainers and are 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.
