Ubuntu Security Notice USN-2937-1
March 21, 2016

webkitgtk vulnerabilities
==========================================================================

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

– Ubuntu 15.10
– Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in WebKitGTK+.

Software Description:
– webkitgtk: 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 versions:

Ubuntu 15.10:
libjavascriptcoregtk-1.0-0 2.4.10-0ubuntu0.15.10.1
libjavascriptcoregtk-3.0-0 2.4.10-0ubuntu0.15.10.1
libwebkitgtk-1.0-0 2.4.10-0ubuntu0.15.10.1
libwebkitgtk-3.0-0 2.4.10-0ubuntu0.15.10.1

Ubuntu 14.04 LTS:
libjavascriptcoregtk-1.0-0 2.4.10-0ubuntu0.14.04.1
libjavascriptcoregtk-3.0-0 2.4.10-0ubuntu0.14.04.1
libwebkitgtk-1.0-0 2.4.10-0ubuntu0.14.04.1
libwebkitgtk-3.0-0 2.4.10-0ubuntu0.14.04.1

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 and Evolution, to make all the
necessary changes.
