nfs-utils available
Red Hat, Inc. Security Advisory
Synopsis: Revised advisory: Updated package for nfs-utils available
Advisory ID: RHSA-2000:043-03
Issue date: 2000-07-17
Updated on: 2000-07-21
Product: Red Hat Linux
Keywords: rpc.statd root compromise
Cross references: N/A
1. Topic:
This is an updated of RHSA-2000:043 that contains further
upgrade instructions.
The rpc.statd daemon in the nfs-utils package shipped in Red Hat
Linux 6.0, 6.1, and 6.2 contains a flaw that could lead to a remote
root break-in.
2. Relevant releases/architectures:
Red Hat Linux 6.0 – i386, alpha, sparc
Red Hat Linux 6.1 – i386, alpha, sparc
Red Hat Linux 6.2 – i386, alpha, sparc
3. Problem description:
The rpc.statd daemon shipped in Red Hat Linux 6.0, 6.1, and 6.2
contains a flaw that could lead to a remote root break-in. Version
0.1.9.1 of the nfs-utils package corrects the problem. Although
there is no known exploit for the flaw in rpc.statd, Red Hat urges
all users running rpc.statd to upgrade to the new nfs-utils
package.
Users should note that in Red Hat Linux 6.0 and 6.1 the
rpc.statd daemon was in the knfsd-clients package. The nfs-utils
package replaces both the knfsd and knfsd-clients packages shipped
in Red Hat Linux 6.0 and 6.1.
On systems running a kernel older than 2.2.16-3, users should
also take this opportunity to upgrade to the latest kernel
release.
4. Solution
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
After installing the new nfs-utils package, the rpc.statd
service must be restarted. To do this, run:
/etc/rc.d/init.d/nfslock restart
