CVE-2020-13753 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.

## Vulnerability Spotlight: Remote code execution vulnerability Apple Safari
Marcin "Icewall" Noga of Cisco Talos discovered this vulnerability. Blog by Jon Munshaw.
The Apple Safari web browser contains a remote code execution vulnerability in its Webkit feature. Specifically, an attacker could trigger a use-after-free condition in WebCore, the DOM-rendering system for Webkit used in Safari. This could give the attacker the ability to execute remote code on the victim machine. A user needs to open a specially crafted, malicious web page in Safari to trigger this vulnerability.
In accordance with our coordinated disclosure policy, Cisco Talos worked with Apple to ensure that these issues are resolved and that an update is available for affected customers.
