A leak of privateClass in the extensions API in Google Chrome prior to 54.0.2840.100 for Linux, and 54.0.2840.99 for Windows, and 54.0.2840.98 for Mac allowed a remote attacker to access privileged JavaScript code via a crafted HTML page.

This update updates QtWebEngine to the 5.8.0 release. QtWebEngine 5.8.0 is part of the Qt 5.8.0 release, but only the QtWebEngine component is included in this update.

The update fixes the following security issues in QtWebEngine 5.7.1:
CVE-2016-5182, CVE-2016-5183, CVE-2016-5189, CVE-2016-5199, CVE-2016-5201, CVE-2016-5203, CVE-2016-5204, CVE-2016-5205, CVE-2016-5206, CVE-2016-5208, CVE-2016-5207, CVE-2016-5210, CVE-2016-5211, CVE-2016-5212, CVE-2016-5213, CVE-2016-5214, CVE-2016-5215. CVE-2016-5216, CVE-2016-5217, CVE-2016-5218, CVE-2016-5219, CVE-2016-5221, CVE-2016-5222, CVE-2016-5223, CVE-2016-5224, CVE-2016-5225, CVE-2016-9650 and CVE-2016-9651.

Other immediately usable changes in QtWebEngine 5.8 include :

  - Based on Chromium 53.0.2785.148 with security fixes from     Chromium up to version 55.0.2883.75. (5.7.1 was based on     Chromium 49.0.2623.111 with security fixes from Chromium     up to version 54.0.2840.87.)

  - The `view-source:` scheme is now supported.

  - User scripts now support metadata (`@include`,     `@exclude`, `@match`) as in Greasemonkey.

  - Some `chrome:` schemes now supported, for instance     `chrome://gpu`.

  - Several bugs were fixed, see     https://code.qt.io/cgit/qt/qtwebengine.git/tree/dist/cha     nges-5.8.0 for details.

The following changes in QtWebEngine 5.8 require compile-time application support and will only be available after applications are rebuilt (and patched to remove the checks for Qt 5.8, because Qt is still version 5.7.1, only QtWebEngine is being updated) :

  - Spellchecking with a forked version of Hunspell. This     Fedora package automatically converts system Hunspell     dictionaries (installed by system RPMs into the     systemwide location) to the Chromium `bdic` format used     by QtWebEngine (using an RPM file trigger). If you wish     to use dictionaries installed manually, use the included     `qwebengine_convert_dict` tool. Alternatively, you can     also download dictionaries directly in the Chromium     `bdic` format.

  - Support for printing directly to a printer. (Note that     QupZilla already supports printing to a printer, because     it can use the printToPdf API that has existed since     QtWebEngine 5.7 to print to a printer with the help of     the `lpr` command-line tool. But other applications such     as KMail require the new direct printing API.)

  - Added a setting to enable printing of CSS backgrounds.

The following new QML APIs are available to developers :

  - Tooltips (HTML5 global title attribute) are now also     supported in the QML API.

  - Qt WebEngine (QML) allows defining custom dialogs /     context menus.

  - Qt WebEngine (QML) on `eglfs` uses builtin dialogs based     on Qt Quick Controls 2.

The version of Google Chrome installed on the remote macOS or Mac OS X host is prior to 54.0.2840.98. It is, therefore, affected by the following vulnerabilities :

  - A remote code execution vulnerability exists in the     FFmpeg component due to an integer overflow condition in     the mov_read_keys() function in mov.c caused by improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this, by convincing a user     to visit a website containing specially crafted content,     to cause a denial of service condition or the execution     of arbitrary code. (CVE-2016-5199)

  - A denial of service vulnerability exists in the V8     component due to an out-of-bounds read error that is     triggered when handling 'Math.sign'. An unauthenticated,     remote attacker can exploit this, by convincing a user     to visit a website containing specially crafted content,     to crash the browser or disclose memory contents.
    (CVE-2016-5200)

  - An information disclosure vulnerability exists due to a     flaw in the expose() function in utils.js. An     unauthenticated, remote attacker can exploit this, by     convincing a user to visit a website containing     specially crafted content, to disclose sensitive     internal class information. (CVE-2016-5201)

  - An unspecified vulnerability exists in the     PruneExpiredDevices() function in dial_registry.cc that     allows an unauthenticated, remote attacker to have an     unspecified impact. (CVE-2016-5202)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
