========================================================================== Ubuntu Security Notice USN-3376-1 August 02, 2017
webkit2gtk vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.04 - Ubuntu 16.04 LTS
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 versions:
Ubuntu 17.04: libjavascriptcoregtk-4.0-18 2.16.6-0ubuntu0.17.04.1 libwebkit2gtk-4.0-37 2.16.6-0ubuntu0.17.04.1
Ubuntu 16.04 LTS: libjavascriptcoregtk-4.0-18 2.16.6-0ubuntu0.16.04.1 libwebkit2gtk-4.0-37 2.16.6-0ubuntu0.16.04.1
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.
