NVD Vulnerability Detail

CVE-2016-1636

Summary	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.

JVN Vulnerability Information

Google Chrome の WebKit/Source/core/dom/PendingScript.cpp における Subresource Integrity 保護メカニズムを回避される脆弱性

Title	Google Chrome の WebKit/Source/core/dom/PendingScript.cpp における Subresource Integrity 保護メカニズムを回避される脆弱性
Summary	Google Chrome の WebKit/Source/core/dom/PendingScript.cpp の PendingScript::notifyFinished 関数は、インテグリティチェックの成功ではなくインテグリティチェックの発生に関するメモリキャッシュ情報に依存するため、Subresource Integrity (別名 SRI) 保護メカニズムを回避される脆弱性が存在します。
Possible impacts	第三者により、同一リソースの二度のロードを誘発されることで、Subresource Integrity (別名 SRI) 保護メカニズムを回避される可能性があります。
Solution	ベンダより正式な対策が公開されています。ベンダ情報を参照して適切な対策を実施してください。
