Detail

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

- Ubuntu 19.10 - 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 19.10:
libjavascriptcoregtk-4.0-18 2.28.0-0ubuntu0.19.10.2
libwebkit2gtk-4.0-37 2.28.0-0ubuntu0.19.10.2
