Use-after-free vulnerability in content/browser/web_contents/web_contents_impl.cc in Google Chrome before 49.0.2623.75 allows remote attackers to cause a denial of service or possibly have unspecified other impact by triggering an image download after a certain data structure is deleted, as demonstrated by a favicon.ico download.

The Web Store inline-installer implementation in the Extensions UI in Google Chrome before 49.0.2623.75 does not block installations upon deletion of an installation frame, which makes it easier for remote attackers to trick a user into believing that an installation request originated from the user’s next navigation target via a crafted web site.

Multiple unspecified vulnerabilities in Google Chrome before 49.0.2623.75 allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

Multiple unspecified vulnerabilities in Google V8 before 4.9.385.26, as used in Google Chrome before 49.0.2623.75, allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

WebKit/Source/core/layout/LayoutBlock.cpp in Blink, as used in Google Chrome before 49.0.2623.75, does not properly determine when anonymous block wrappers may exist, which allows remote attackers to cause a denial of service (incorrect cast and assertion failure) or possibly have unspecified other impact via crafted JavaScript code.

The Content Security Policy (CSP) implementation in Blink, as used in Google Chrome before 49.0.2623.75, does not ignore a URL’s path component in the case of a ServiceWorker fetch, which allows remote attackers to obtain sensitive information about visited web pages by reading CSP violation reports, related to FrameFetchContext.cpp and ResourceFetcher.cpp.
