CVE-2012-6465
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 · uneditedOpera before 12.10 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a malformed SVG image.
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 confidenceA vulnerability in Opera browsers prior to version 12.10 allows remote attackers to execute arbitrary code or cause a denial of service by tricking users into opening malformed SVG image content. The malformed SVG triggers a parsing error or memory corruption that can be exploited for code execution or cause the application to crash.

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 checksWork through these to decide whether this CVE applies to you.
-
Check if Opera browser is installedLook for opera.exe in common installation paths such as C:\Program Files\Opera\ or C:\Program Files (x86)\Opera\, or check for Opera in the list of installed programs via Control Panel > Programs and Features.Affected if Opera browser is found on the system
-
Determine installed Opera versionRight-click on opera.exe, select Properties, and view the Details tab for the Product version, or open Opera and navigate to Help > About Opera.Affected if Unable to determine the version or version is <= 12.10
-
Verify version against vulnerable rangeCompare the installed version number to 12.10. The vulnerable versions are any Opera version <= 12.10.Affected if Installed version is 12.10 or lower (for example: 12.09, 12.00, 11.x, 10.x, etc.)
The user is affected if Opera browser is installed and its version is 12.10 or lower, since the vulnerability exists in versions prior to 12.10.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade Opera to version 12.10 or later, or migrate to an actively supported browser if Opera updates are no longer available.
Opera 12.10 or later (or migrate to modern Chromium-based Opera 26+)
- 1. Download the latest Opera browser from the official website (www.opera.com)
- 2. Close any running instances of Opera browser
- 3. Install the new version of Opera
- 4. After installation, verify the version by navigating to Opera > Help > About Opera
