Date: Mon, 17 Jul 2000 19:15:00 -0400 From: bugzilla@REDHAT.COM Subject: [RHSA-2000:043-02] Updated package for nfs-utils available To: BUGTRAQ@SECURITYFOCUS.COM

--------------------------------------------------------------------- Red Hat, Inc. Security Advisory

Synopsis: Updated package for nfs-utils available Advisory ID: RHSA-2000:043-02 Issue date: 2000-07-17 Updated on: 2000-07-17 Product: Red Hat Linux Keywords: rpc.statd root compromise Cross references: N/A ---------------------------------------------------------------------

1. Topic:

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.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
