Descriptions

The PendingScript::notifyFinished function in WebKit/Source/core/dom/PendingScript.cpp in Google Chrome before 49.0.2623.75 relies on memory-cache information about integrity-check occurrences instead of integrity-check successes, which allows remote attackers to bypass the Subresource Integrity (aka SRI) protection mechanism by triggering two loads of the same resource.

La función PendingScript::notifyFinished en WebKit/Source/core/dom/PendingScript.cpp en Google Chrome en versiones anteriores a 49.0.2623.75 confía en la información de memoria caché sobre ocurrencias de control de integridad en vez de éxitos de control de integridad, lo que permite a atacantes remotos eludir el mecanismo de protección Subresource Integrity (también conocido como SRI) desencadenando dos cargas del mismo recurso.
