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
ZoneAlarm and ZoneAlarm Pro allows a local attacker to cause a denial of service by running a trojan to initialize a ZoneAlarm mutex object which prevents ZoneAlarm from starting.

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

ZoneAlarm's firewall startup process relies on a named mutex object. A local attacker can run a trojan that pre-initializes this specific mutex before ZoneAlarm attempts to start. When ZoneAlarm tries to create its mutex, it finds it already exists and fails to initialize, preventing the firewall from starting and leaving the system unprotected.

MitigationThis is a legacy vulnerability in 2001-era software. The remediation involves updating to current ZoneAlarm/Check Point endpoint protection products, which have fixed mutex handling. If legacy software must be used, implement application whitelisting to prevent unauthorized executables from pre-creating the mutex.

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 if ZoneAlarm is installed
    Check for ZoneAlarm or ZoneAlarm Pro installation directories or registry entries for the product (commonly in Program Files or via Add/Remove Programs)
    Affected if ZoneAlarm or ZoneAlarm Pro software is found on the system
  2. Determine the installed version
    Locate version information in the installed program's about dialog, executable properties, or registry entry for the product version
    Affected if The version is 2.6 or higher for ZoneAlarm Pro, or any version for ZoneAlarm (all versions affected)
  3. Verify firewall startup status
    Observe whether ZoneAlarm's firewall initializes and runs when the system starts or when the ZoneAlarm service/application is launched
    Affected if The firewall fails to start or reports it cannot initialize its protection modules

A system is affected if it runs any version of ZoneAlarm (all versions) or ZoneAlarm Pro 2.6+, where the firewall fails to initialize due to a pre-existing mutex.
