Use-after-free vulnerability in core/events/TreeScopeEventContext.cpp in the DOM implementation in Blink, as used in Google Chrome before 40.0.2214.91, allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that triggers improper maintenance of TreeScope data.

Security readout for executives and security teams

This is an old Chrome/Blink browser memory-safety flaw. A malicious webpage using crafted JavaScript could crash the browser and may have caused other unspecified impact. The provided sources identify Google Chrome before 40.0.2214.91 as affected, but do not provide CVSS scoring or confirmed exploitation. Exposure is mainly legacy systems running Google Chrome or Chromium-derived Blink builds before 40.0.2214.91. Current exposure depends on whether old desktop images, kiosks, appliances, or embedded browser components remain in use. Treat this as a legacy exposure issue. It should not drive emergency response unless old Chrome/Blink builds are still deployed, especially on internet-browsing workstations, kiosks, or embedded systems. Mitigation focus: Upgrade Chrome or Chromium-derived packages to versions containing the 40.0.2214.91 fix or later.; Check Linux distribution advisories for vendor-packaged browser updates.; Retire unsupported systems that cannot receive modern browser security updates..
