A security issue affects these releases of Ubuntu and its
derivatives:

Summary

Several security issues were fixed in WebKitGTK+.

Software description

webkit2gtk
– Web content engine library for GTK+

Details

A large number of security issues were discovered in the WebKitGTK+ Web and
JavaScript engines. If a user were tricked into viewing a malicious
website, a remote attacker could exploit a variety of issues related to web
browser security, including cross-site scripting attacks, denial of service
attacks, and arbitrary code execution.

Update instructions

The problem can be corrected by updating your system to the following
package version:

Ubuntu 17.04:: libwebkit2gtk-4.0-37

2.18.0-0ubuntu0.17.04.2; libjavascriptcoregtk-4.0-18

2.18.0-0ubuntu0.16.04.2

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart any applications
that use WebKitGTK+, such as Epiphany, to make all the necessary changes.
