Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
rquotad in nfs-utils (rquota_server.c) before 1.0.6-r6 on 64-bit architectures does not properly perform an integer conversion, which leads to a stack-based buffer overflow and allows remote attackers to execute arbitrary code via a crafted NFS request.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

nfs-utils version 1.0.6-r6 or later, or equivalent patched version from Red Hat Enterprise Linux 3.0 errata

  1. Identify the nfs-utils package version currently installed (e.g., using 'rpm -qa | grep nfs-utils' or 'dpkg -l | grep nfs-utils')
  2. For Red Hat Enterprise Linux 3.0 systems, obtain the updated nfs-utils package from Red Hat's errata or update channels for RHEL 3.0
  3. Apply the update using the appropriate package manager (e.g., 'up2date nfs-utils' or 'yum update nfs-utils' or download and install the RPM manually)
  4. Verify the updated version is 1.0.6-r6 or later, or contains the CVE-2004-0946 fix
  5. Restart the rquotad service if it is running (e.g., '/etc/init.d/rpc.rquotad restart' or 'service rpc-rquotad restart')
  6. Confirm the service is listening on the appropriate port (typically 20011) and functioning correctly
Caveat Upgrading nfs-utils may require service restart; test in non-production environment first to ensure compatibility with NFS client configurations
