Synopsis

The remote Fedora host is missing a security update.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected qt5-qtwebengine package.
