CVE-2011-1109: Google Chrome before 9.0.597.107 does not properly process nodes in Cascading Style Sheets (CSS) stylesheet...

Google Chrome before 9.0.597.107 does not properly process nodes in Cascading Style Sheets (CSS) stylesheets, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that lead to a "stale pointer."

Analyst readout for executives and security teams

Plain-English summary

This is an old Google Chrome browser flaw involving CSS stylesheet handling. A remote attacker could crash the browser and the original description leaves room for unspecified additional impact. The source bundle identifies Chrome before 9.0.597.107, but gives limited technical detail and no CVSS score.

Executive priority

Low immediate urgency for normally managed environments, because this is a 2011 browser issue and no active exploitation is cited. Raise priority if legacy Chrome, embedded Chromium, kiosks, or unmanaged browsing systems remain in service.

Technical view

Google Chrome before 9.0.597.107 improperly processed nodes in CSS stylesheets, leading to a stale pointer condition. The documented impact is denial of service, with possible unspecified other impact. The attack vector is remote, but the supplied sources do not describe exact vectors, exploit mechanics, or affected downstream products beyond the Chrome version statement.

Likely exposure

Exposure is most plausible on systems still running Google Chrome versions older than 9.0.597.107 or embedded legacy Chromium code. Modern managed endpoints are unlikely to be exposed, but legacy images, kiosks, archived VDI, and unmanaged systems should be checked.

Exploitation context

The bundle does not show CISA KEV listing or cited active exploitation. It only states that remote attackers could trigger the issue through unknown CSS stylesheet-related vectors causing a stale pointer. Treat exploit details as incomplete.

Researcher notes

The useful facts are sparse: stale pointer during CSS node processing, Chrome before 9.0.597.107, denial of service, and possible unspecified impact. The Apple references may indicate downstream advisory coverage, but this bundle does not define affected Apple products or exact fixes.

Mitigation direction

  • Upgrade Chrome to at least 9.0.597.107, preferably a current supported browser.
  • Remove or isolate unsupported legacy Chrome or Chromium-based deployments.
  • Check Google and Apple vendor advisories for product-specific remediation details.
  • Ensure endpoint management blocks use of obsolete browser versions.
  • Prioritize remediation on systems browsing untrusted web content.

Validation and detection

  • Inventory browser versions across endpoints, VDI, kiosks, and legacy images.
  • Confirm no managed Chrome installation is older than 9.0.597.107.
  • Review vulnerability scanner findings, including available OVAL checks.
  • Check exception lists for systems allowed to run obsolete browsers.
  • Document any Apple-advisory-related exposure only after vendor confirmation.
