CVE-2010-3019
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 · uneditedHeap-based buffer overflow in Opera before 10.61 allows remote attackers to execute arbitrary code or cause a denial of service (application crash or hang) via vectors related to HTML5 canvas painting operations that occur during the application of transformations.
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 confidenceHeap-based buffer overflow in Opera browser's HTML5 canvas rendering engine. The vulnerability occurs when canvas painting operations are performed during the application of transformation matrices, allowing remote attackers to corrupt heap memory and potentially execute arbitrary code or crash the browser.

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.
-
Identify installed Opera versionRun 'opera --version' in terminal or check Help > About Opera in the browserAffected if Version is 10.60 or lower, or matches any of the specific versions listed (1.00, 2.00, 2.10, 2.12, 3.00, 3.10, 3.21, 3.50, 3.51, 3.60, 3.61)
-
Verify canvas module is enabledCheck Opera's configuration for canvas-related settings or inspect browser runtime for canvas supportAffected if HTML5 canvas support is enabled and the browser is an affected version
-
Identify canvas usage with transformation matricesAudit any web content or applications that use the HTML5 canvas API with transformation operations such as setTransform, transform, rotate, scale, or translateAffected if Canvas rendering with transformation matrices is performed in an affected Opera version
-
Check for crash logs or memory corruption indicatorsReview Opera's crash reports or system event logs for heap corruption patterns related to canvas operationsAffected if Heap corruption or browser crashes occur during canvas transformation operations
You are affected if Opera version 10.60 or lower is installed AND HTML5 canvas with transformation matrix operations is being used or rendered in the browser.

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 10.61 or later. If legacy Opera is required, consider using alternative browsers or implementing network-level controls to block malicious canvas content.
Opera 10.61 or later
- Upgrade Opera Browser to version 10.61 or later to remediate the heap-based buffer overflow vulnerability.
- Verify the current Opera version by navigating to 'Help' > 'About Opera' or checking the application version.
- Download Opera 10.61 or the latest stable version from the official Opera website (www.opera.com).
- Install the downloaded version, restarting the browser if prompted.
