Bypassing Subresource Integrity Protection in Google Chrome

CVE-2016-1636 · HIGH Severity

AV:N/AC:L/AU:N/C:P/I:P/A:P

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.
