Ubuntu Security Notice USN-3079-1
September 14, 2016
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 introspection
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 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 applications
that use WebKitGTK+, such as Epiphany, to make all the necessary changes.
