========================================================================== Ubuntu Security Notice USN-3551-1 January 30, 2018
webkit2gtk vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10 - Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in WebKitGTK+.
Software Description: - webkit2gtk: Web content engine library for GTK+
Details:
Multiple security issues were discovered in the WebKitGTK+ Web and JavaScript engines. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, spoof the user interface, or execute arbitrary code. (CVE-2018-4088, CVE-2018-4096, CVE-2017-7153, CVE-2017-7160, CVE-2017-7161, CVE-2017-7165, CVE-2017-13884, CVE-2017-13885)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.10: libjavascriptcoregtk-4.0-18 2.18.6-0ubuntu0.17.10.1 libwebkit2gtk-4.0-37 2.18.6-0ubuntu0.17.10.1
Ubuntu 16.04 LTS: libjavascriptcoregtk-4.0-18 2.18.6-0ubuntu0.16.04.1 libwebkit2gtk-4.0-37 2.18.6-0ubuntu0.16.04.1
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.
