chromium: multiple vulnerabilities

Multiple unspecified vulnerabilities in Google V8 before 4.2.77.14, as used in Google Chrome before 42.0.2311.90, allow attackers to cause a denial of service or possibly have other impact via unknown vectors. (CVE-2015-3333)

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. (CVE-2015-3334)

The NaClSandbox::InitializeLayerTwoSandbox function in components/nacl/loader/sandbox_linux/nacl_sandbox_linux.cc in Google Chrome before 42.0.2311.90 does not have RLIMIT_AS and RLIMIT_DATA limits for Native Client (aka NaCl) processes, which might make it easier for remote attackers to conduct row-hammer attacks or have unspecified other impact by leveraging the ability to run a crafted program in the NaCl sandbox. (CVE-2015-3335)

Google Chrome before 42.0.2311.90 does not always ask the user before proceeding with CONTENT_SETTINGS_TYPE_FULLSCREEN and CONTENT_SETTINGS_TYPE_MOUSELOCK changes, which allows user-assisted remote attackers to cause a denial of service (UI disruption) by constructing a crafted HTML document containing JavaScript code with requestFullScreen and requestPointerLock calls, and arranging for the user to access this document with a file: URL. (CVE-2015-3336)
