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
Use-after-free vulnerability in Google Chrome before 20.0.1132.43 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to SVG resources.

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

Use-after-free vulnerability in Google Chrome's SVG rendering engine before version 20.0.1132.43 allows remote attackers to cause denial of service or potentially execute arbitrary code by crafting malicious SVG resources that free memory prematurely while still maintaining references to that memory.

MitigationUpdate Google Chrome to version 20.0.1132.43 or later to obtain the patched version of the SVG resource handling code.

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. Determine installed Google Chrome version
    Navigate to chrome://settings/help or use the Chrome menu > Help > About Google Chrome to display the current version number
    Affected if The displayed version is 20.0.1132.42 or lower, or falls within 20.0.1132.0 through 20.0.1132.10
  2. Verify SVG rendering is enabled
    Navigate to chrome://settings/advanced and confirm 'Enable SVG' is not disabled, or inspect chrome://flags for SVG-related settings
    Affected if SVG rendering is explicitly disabled (unlikely as it is enabled by default)
  3. Compare version against vulnerability range
    If your version is 20.0.1132.43 or higher, you are not in the affected range. If it is 20.0.1132.42 or lower, or one of the specific 20.0.1132.x versions from 0-10, you are affected
    Affected if Installed version is 20.0.1132.42 or any version from 20.0.1132.0 through 20.0.1132.10

You are affected if Google Chrome version is 20.0.1132.42 or lower, or matches any version from 20.0.1132.0 through 20.0.1132.10, and SVG rendering is enabled (default state).
