New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Fedora host is missing a security update.

Description

This is a bug fix release in the stable 2.22 series.

- [CVE-2018-4437](https://www.webkitgtk.org/security/WSA-2 018-0009.html#CVE-2018-4437)

-- Processing maliciously crafted web content may lead to arbitrary code execution. Multiple memory corruption issues were addressed with improved memory handling.

- Fix the build with ENABLE_VIDEO=OFF and ENABLE_OPENGL=OFF.

- Fix several crashes.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
