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

  o Ubuntu 19.10
  o Ubuntu 19.04
  o Ubuntu 18.04 LTS

Summary

Several security issues were fixed in WebKitGTK+.

Software Description

  o 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 19.10
    libjavascriptcoregtk-4.0-18 - 2.26.2-0ubuntu0.19.10.1
    libwebkit2gtk-4.0-37 - 2.26.2-0ubuntu0.19.10.1
Ubuntu 19.04

    libwebkit2gtk-4.0-37 - 2.26.2-0ubuntu0.18.04.1

To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades .
