USN-3460-1: WebKitGTK+ vulnerabilities

Ubuntu Security Notice USN-3460-1

23rd October, 2017

webkit2gtk vulnerabilities

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

    Ubuntu 17.04
    Ubuntu 16.04 LTS


Several security issues were fixed in WebKitGTK+.

Software description

    webkit2gtk - Web content engine library for GTK+


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 2.18.0-0ubuntu0.17.04.2 
Ubuntu 16.04 LTS:
    libwebkit2gtk-4.0-37 2.18.0-0ubuntu0.16.04.2 
    libjavascriptcoregtk-4.0-18 2.18.0-0ubuntu0.16.04.2 

To update your system, please follow these instructions:

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.
