Details

USN-3781-1 fixed vulnerabilities in WebKitGTK+. The updated package was
missing some header files, preventing certain applications from building.
This update fixes the problem.

We apologize for the inconvenience.

Original advisory 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 18.04

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.
