    webkit2gtk vulnerabilities


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

    • Ubuntu 17.04
    • Ubuntu 16.10
    • 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 version:

    Ubuntu 17.04:
    libwebkit2gtk-4.0-37 2.16.3-0ubuntu0.17.04.1
    libjavascriptcoregtk-4.0-18 2.16.3-0ubuntu0.17.04.1
    Ubuntu 16.10:
    libwebkit2gtk-4.0-37 2.16.3-0ubuntu0.16.10.1
    libjavascriptcoregtk-4.0-18 2.16.3-0ubuntu0.16.10.1
    Ubuntu 16.04 LTS:
    libwebkit2gtk-4.0-37 2.16.3-0ubuntu0.16.04.1
    libjavascriptcoregtk-4.0-18 2.16.3-0ubuntu0.16.04.1

    To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

    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.
