Description
Use-after-free vulnerability in the MutationObserver::disconnect function in core/dom/MutationObserver.cpp in the DOM implementation in Blink, as used in Google Chrome before 42.0.2311.135, allows remote attackers to cause a denial of service or possibly have unspecified other impact by triggering an attempt to unregister a MutationObserver object that is not currently registered.
