New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Fedora host is missing a security update.

Description

This update for the `glibc` package addresses one moderate security vulnerability and a minor defect :

- CVE-2018-19591: A file descriptor leak in `if_nametoindex` can lead to a denial of service due to resource exhaustion when processing `getaddrinfo` calls with crafted host names. Reported by Guido Vranken.
(RHBZ#1654000)

- Parallel building of locales led to nondeterminism in the RPM build process. (RHBZ#1652228)

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.

Solution

Update the affected glibc package.
