Details
Updated nfs-utils packages that fix a flaw leading to possible rpc.mountd
crashes are now available.
The nfs-utils package contains the rpc.mountd program, which implements the
NFS mount protocol.
A flaw was discovered in versions of rpc.mountd in nfs-utils versions after
1.0.3 and prior to 1.0.6. When mounting a directory, rpc.mountd could
crash if the reverse lookup of the client in DNS failed to match the
forward lookup. An attacker who has the ability to mount remote
directories from a server could make use of this flaw to cause a denial of
service by making rpc.mountd crash.
Users are advised to upgrade to these updated packages, which contain
nfs-utils 1.0.6 and is not vulnerable to this issue.
NOTE: Red Hat Enterprise Linux 2.1 includes a version of rpc.mountd that is
not vulnerable to this issue.
Solution
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.
