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
Some Xerox printers (such as the Phaser 3320 V53.006.16.000) were affected by one or more stack-based buffer overflow vulnerabilities in the Google Cloud Print implementation that would allow an unauthenticated attacker to execute arbitrary code on the device. This was caused by an insecure handling of the register parameters, because the size used within a memcpy() function, which copied the action value into a local variable, was not checked properly.

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

Stack-based buffer overflow in Xerox printers' Google Cloud Print implementation. The memcpy() function copies an action value into a local variable without proper size validation, allowing unauthenticated remote attackers to execute arbitrary code.

MitigationApply vendor firmware update when available; until then, disable Google Cloud Print on affected devices or isolate them on a restricted network segment.

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 the printer model
    Access the printer's web interface (embedded web server) or print a configuration page to confirm the device is a Xerox Phaser 3320
    Affected if The device model is Xerox Phaser 3320
  2. Check the installed firmware version
    Navigate to the printer web interface > Status or General Setup page, or print a configuration/info page to locate the firmware version field
    Affected if Firmware version equals exactly v53.006.16.000
  3. Verify Google Cloud Print is enabled
    Access the printer web interface > Scan to... > Cloud or Print Services > Google Cloud Print settings, or check the configuration page for Google Cloud Print status
    Affected if Google Cloud Print is currently enabled on the device

The device is affected if it is a Xerox Phaser 3320 running firmware v53.006.16.000 with Google Cloud Print enabled.
