USN-4281-1: WebKitGTK+ vulnerabilities
18 February 2020
Several security issues were fixed in WebKitGTK+.
- webkit2gtk - Web content engine library for GTK+
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 - 2.26.4-0ubuntu0.19.10.1
- libwebkit2gtk-4.0-37 - 2.26.4-0ubuntu0.18.04.1
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.
