The remote Red Hat host is missing a security update.
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.
