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

• Ubuntu 18.04 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 18.04 LTS

libjavascriptcoregtk-4.0-18 - 2.22.2-0ubuntu0.18.04.1
