New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Fedora host is missing a security update.

Description

This update addresses various overflow conditions that could result in possible memory read/write out of bounds errors or zero byte allocations when connected to a malicious server.

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