10 October 2018
USN-3781-1 introduced a regression in WebKitGTK+.
- webkit2gtk - Web content engine library for GTK+
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
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.
The problem can be corrected by updating your system to the following package versions:
- libwebkit2gtk-4.0-37 - 2.22.2-0ubuntu0.18.04.2
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.
