CVE-2020-9862 WebKitGTK vulnerabilities
Title: WebKitGTK vulnerabilities
Summary: Several security issues were fixed in WebKitGTK.
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.
Instructions: 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.
