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 before 11.67 and 12.x before 12.02 allows remote attackers to cause truncation of a dialog, and possibly trigger downloading and execution of arbitrary programs, via a crafted web site.

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

Opera browsers before versions 11.67 and 12.02 contain a vulnerability where visiting a crafted website can cause dialog truncation. This dialog manipulation can potentially be exploited to trigger downloading and execution of arbitrary programs on the affected system.

MitigationUpgrade Opera to version 11.67 or 12.02 and later, or migrate to a supported browser. Organizations should identify and remediate any remaining installations of vulnerable Opera versions.

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. Locate Opera browser installation
    Search for Opera executable (opera.exe) in common installation directories such as C:\Program Files\Opera, C:\Program Files (x86)\Opera, or check registry under HKEY_LOCAL_MACHINE\SOFTWARE\Opera Software or HKEY_CURRENT_USER\Software\Opera Software
    Affected if Opera browser is found installed on the system
  2. Determine installed Opera version
    Right-click opera.exe, select Properties, then view the Details tab for version information. Alternatively, launch Opera, go to Help > About Opera to view the exact version number
    Affected if The displayed version is 11.66 or earlier, or falls within the listed affected version numbers (11.00, 2.00, 2.10, 2.12, 3.00, 3.10, 3.21, 3.50, 3.51, 3.60, 3.61)
  3. Identify Opera product type
    Check the Help > About Opera dialog to confirm the specific Opera product name and build number, as some listed versions may refer to different Opera-based products or bundled versions
    Affected if The product is a version of Opera Browser at 11.66 or lower, or matches any version explicitly listed in the affected products range

The system is affected if any Opera browser installation found is version 11.66 or earlier, or matches the specific affected version numbers, and the browser is capable of rendering web content and displaying dialogs.
