Ubuntu 18.04 LTS : webkit2gtk vulnerabilities (USN-3781-1)

Medium Nessus Plugin ID 117914

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
