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
Norton AntiVirus 5.00.01C with the Novell Netware client does not properly restart the auto-protection service after the first user has logged off of the system.

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

Norton AntiVirus 5.00.01C when deployed with the Novell Netware client fails to properly restart its auto-protection service after the first user logs off the system. This leaves the system vulnerable as the real-time scanning protection becomes inactive following user logoff.

MitigationUpgrade from the obsolete Norton AntiVirus 5.00.01C to a current supported version, or ensure the auto-protection service is configured to restart properly after user logoff events.

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 Norton AntiVirus version
    Check the installed version of Norton AntiVirus on the system. This can typically be found in Add/Remove Programs, the program's About section, or by checking the executable version information (e.g., right-click nav.exe or the program files directory).
    Affected if The installed version is Norton AntiVirus 5.00.01C specifically.
  2. Identify Novell Client version
    Check the installed version of the Novell NetWare client software. This can be found in Add/Remove Programs under Novell client entries, or by checking the client software's version information in the system or network configuration.
    Affected if The installed Novell Client version is 3.1.
  3. Confirm both products coexist
    Verify that both Norton AntiVirus 5.00.01C and Novell Client 3.1 are installed on the same system. The vulnerability only manifests when both are present together.
    Affected if Both products are installed concurrently on the same machine.
  4. Test auto-protection service after logoff
    Log in with one user, verify Norton AntiVirus auto-protection is active, then log off that user and log in with a different user. Check whether the auto-protection service (NAV Auto-Protect or similar) is running. This can be done via Task Manager, Services console, or the Norton AntiVirus interface.
    Affected if The auto-protection service is NOT running or inactive after the first user logs off, leaving real-time scanning disabled.

A system is affected if it has Norton AntiVirus 5.00.01C installed alongside Novell Client 3.1, and the auto-protection service fails to restart after a user logs off, resulting in inactive real-time scanning protection.
