webkit2gtk vulnerabilities
==========================
==========================
========================

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

- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in WebKitGTK+.

Software Description:
- webkit2gtk: JavaScript engine library from WebKitGTK+ - GObject introsp=
ection

Details:

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

Update instructions:

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

Ubuntu 16.04 LTS:
libjavascriptcoregtk-4.0-18 2.12.5-0ubuntu0.16.04.1
libwebkit2gtk-4.0-37 2.12.5-0ubuntu0.16.04.1

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