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
Unspecified vulnerability in the Sun Solaris RPC services library (librpcsvc) on Solaris 8 through 10 allows remote attackers to cause a denial of service (mountd crash) via unspecified packets to a server that exports many filesystems, and allows local users to cause a denial of service (automountd crash) via unspecified requests to mount filesystems from a server that exports many filesystems.

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 · moderate confidence

A denial of service vulnerability exists in the Sun Solaris librpcsvc library affecting Solaris 8 through 10. Remote attackers can crash mountd by sending unspecified packets to servers exporting many filesystems, while local users can crash automountd via unspecified filesystem mount requests from servers exporting many filesystems. The exact vulnerability mechanism is not specified in the available description.

MitigationApply Oracle Solaris patches for this vulnerability; if patches are unavailable for end-of-life Solaris versions, consider upgrading to a supported OS release or disabling/restricting RPC mountd and automountd services if not required.

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. Check Solaris version
    Run 'uname -a' or 'cat /etc/release' to determine the installed Solaris version. Look for 8.0, 9.0, or 10.0 in the output.
    Affected if The system runs Solaris 8, 9, or 10.
  2. Verify if mountd RPC service is running
    Run 'rpcinfo -p localhost' or 'rpcinfo -p' and look for program number 100005 (mountd) in the output. Alternatively, check if the process 'rpc.mountd' is running using 'ps -ef | grep mountd'.
    Affected if The mountd RPC service (program 100005) is actively running on the system.
  3. Verify if automountd service is running
    On Solaris 10, run 'svcs -a | grep automount' to check service status. On older versions, check for 'automountd' processes using 'ps -ef | grep automount'.
    Affected if The automountd daemon is actively running on the system.
  4. Check RPC service exposure (if remotely exploitable)
    Run 'rpcinfo -p' to list all registered RPC services. For remote attack vector, verify that mountd is bound to a network-exposed port and accessible from network.
    Affected if Mountd is network-exposed and the system accepts RPC connections from untrusted networks.

The system is vulnerable if it runs Solaris 8, 9, or 10 AND has either mountd or automountd services actively running, with mountd exposure to network attack vectors for remote DoS.
