Microsoft Internet Explorer 9 through 11 allows remote attackers to read the browser history via a crafted web site.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 38.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Microsoft Silverlight 5 before 5.1.40416.00 allows remote attackers to bypass intended integrity-level restrictions via a crafted Silverlight application, aka "Microsoft Silverlight Out of Browser Application Vulnerability."

browser/ui/website_settings/website_settings.cc in Google Chrome before 42.0.2311.90 does not always display "Media: Allowed by you" in a Permissions table after the user has granted camera permission to a web site, which might make it easier for user-assisted remote attackers to obtain sensitive video data from a device's physical environment via a crafted web site that turns on the camera at a time when the user believes that camera access is prohibited.

The SearchEngineTabHelper::OnPageHasOSDD function in browser/ui/search_engines/search_engine_tab_helper.cc in Google Chrome before 42.0.2311.90 does not prevent use of a file: URL for an OpenSearch descriptor XML document, which might allow remote attackers to obtain sensitive information from local files via a crafted (1) http or (2) https web site.

Use-after-free vulnerability in the OpenPDFInReaderView::Update function in browser/ui/views/location_bar/open_pdf_in_reader_view.cc in Google Chrome before 41.0.2272.76 might allow user-assisted remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact by triggering interaction with a PDFium "Open PDF in Reader" button that has an invalid tab association.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 37.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
