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
Integer overflow in the FilterEffect::copyImageBytes function in platform/graphics/filters/FilterEffect.cpp in the SVG filter implementation in WebCore in WebKit in Google Chrome before 11.0.696.65 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via crafted dimensions.

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

Integer overflow in the FilterEffect::copyImageBytes function in WebCore's SVG filter implementation in WebKit allows attackers to trigger a buffer condition via crafted image dimensions, potentially causing denial of service (application crash) or unspecified other impact.

MitigationUpdate Google Chrome to version 11.0.696.65 or later, or apply the corresponding WebKit patch to address the integer overflow in the SVG filter processing.

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. Check installed Google Chrome version
    Navigate to chrome://settings/help or use the Chrome menu > About Google Chrome to view the version number
    Affected if Version number is 11.0.696.64 or lower
  2. Verify WebKit version embedded in Chrome (optional)
    Navigate to chrome://version to view build information, which includes the WebKit version
    Affected if WebKit version corresponds to the vulnerable release (before the 11.0.696.65 security update)
  3. Confirm SVG filter functionality is accessible
    The vulnerability is in WebCore SVG filter processing. In Chrome, SVG support is enabled by default for all users. No configuration check needed unless SVG has been explicitly disabled via enterprise policy
    Affected if SVG rendering is enabled (default state) and user can process SVG content

User is affected if Google Chrome version is 11.0.696.64 or earlier, since the integer overflow in the FilterEffect::copyImageBytes SVG filter code path exists in those versions
