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
Opera 9.52 and earlier allows remote attackers to cause a denial of service (unusable browser) by calling the window.print function in a loop, aka a "printing DoS attack," possibly a related issue to CVE-2009-0821.

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

Opera 9.52 and earlier contains a denial of service vulnerability where a remote attacker can make the browser unusable by repeatedly calling the JavaScript window.print() function in a loop, continuously triggering printing dialogs or processes.

MitigationUpgrade Opera to a version newer than 9.52, or disable JavaScript in the browser as a workaround.

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. Confirm Opera browser is installed
    Check for Opera executable: on Windows look for opera.exe in Program Files or the Opera install directory, or run 'opera --version' from command line if in PATH
    Affected if Opera browser is present on the system
  2. Identify installed Opera version
    Open Opera, go to Help > About Opera, or run 'opera --version' from command line, or right-click opera.exe and view Properties > Details for version information
    Affected if Version is 9.52 or lower, or matches 5.0, 5.02, 5.10, 5.11, 5.12, 6.0, 6.1, 6.01, 6.02, 6.03, or 6.04
  3. Verify JavaScript is enabled
    In Opera, go to Settings > Preferences > Advanced > JavaScript, or check for javaenabled setting in opera6.ini configuration file
    Affected if JavaScript is enabled in the browser settings

User is affected if Opera browser version is 9.52 or earlier (including listed versions 5.x and 6.x) AND JavaScript is enabled, allowing malicious webpages to trigger continuous print dialogs via window.print() loop.
