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
Buffer overflow in the pfs_mountd.rpc RPC daemon in the Portable File System (PFS) in HP-UX B.11.00, B.11.11, and B.11.23 allows remote attackers to execute arbitrary code by sending "a call to procedure 5, followed by a crafted payload to procedure 2."

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.

dbcve analysis · high confidence

Buffer overflow in the pfs_mountd.rpc RPC daemon in HP-UX Portable File System (PFS) allows remote attackers to execute arbitrary code by sending a call to procedure 5 followed by a crafted payload to procedure 2. This is a stack-based buffer overflow in an RPC service running on HP-UX B.11.00, B.11.11, and B.11.23.

MitigationApply HP patches for this vulnerability or, if PFS is not required, disable the pfs_mountd.rpc service entirely. Network segmentation can limit exposure since this is a network-exploitable flaw.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify HP-UX version
    Run 'uname -a' or 'swlist -l product | grep HP-UX' to determine the exact HP-UX release version
    Affected if The version is B.11.00, B.11.11, or B.11.23
  2. Verify PFS software is installed
    Check if the HP-UX Portable File System (PFS) software product is installed by running 'swlist -l product | grep -i pfs' or reviewing installed software bundles
    Affected if PFS is installed on the system
  3. Confirm pfs_mountd.rpc service is running
    Check for the pfs_mountd.rpc daemon process using 'ps -ef | grep pfs_mountd' or by querying RPC services with 'rpcinfo -p' for program number 100069 (or the pfs_mountd service)
    Affected if The pfs_mountd.rpc daemon is actively running and registered as an RPC service

A system is affected if it is running HP-UX B.11.00, B.11.11, or B.11.23 with the PFS software installed and the pfs_mountd.rpc daemon actively running and exposed to the network.
