Detail

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

- Ubuntu 18.04 LTS - Ubuntu 17.10 - Ubuntu 16.04 LTS

Summary:

A security issue was fixed in WebKitGTK+.

Software Description: - webkit2gtk: Web content engine library for GTK+

Details:

Ivan Fratric discovered that WebKitGTK+ incorrectly handled certain web content. If a user were tricked into viewing a malicious website, a remote attacker could possibly exploit this to execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04 LTS:
libjavascriptcoregtk-4.0-18 2.20.2-0ubuntu0.18.04.1
libwebkit2gtk-4.0-37 2.20.2-0ubuntu0.18.04.1

Ubuntu 17.10:
libjavascriptcoregtk-4.0-18 2.20.2-0ubuntu0.17.10.1
libwebkit2gtk-4.0-37 2.20.2-0ubuntu0.17.10.1

Ubuntu 16.04 LTS:
libjavascriptcoregtk-4.0-18 2.20.2-0ubuntu0.16.04.1
libwebkit2gtk-4.0-37 2.20.2-0ubuntu0.16.04.1

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.
