Medium Nessus Plugin ID 106534
Synopsis
The remote Ubuntu host is missing one or more security-related patches.
Description
Multiple security issues were discovered in the WebKitGTK+ Web and JavaScript engines. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, spoof the user interface, or execute arbitrary code. (CVE-2018-4088, CVE-2018-4096, CVE-2017-7153, CVE-2017-7160, CVE-2017-7161, CVE-2017-7165, CVE-2017-13884, CVE-2017-13885).
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.
Solution
Update the affected libjavascriptcoregtk-4.0-18 and / or libwebkit2gtk-4.0-37 packages.
