webkit2gtk vulnerabilities
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 21.10
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in WebKitGTK.

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

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 21.10:
  libjavascriptcoregtk-4.0-18     2.36.0-0ubuntu0.21.10.3
  libwebkit2gtk-4.0-37            2.36.0-0ubuntu0.21.10.3

Ubuntu 20.04 LTS:
  libjavascriptcoregtk-4.0-18     2.36.0-0ubuntu0.20.04.3
  libwebkit2gtk-4.0-37            2.36.0-0ubuntu0.20.04.3

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.
