Fedora 27 : glibc (2017-0d3fdd3d1f)

critical Nessus Plugin ID 105814
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.


The remote Fedora host is missing a security update.


This update adds support for the IBM858 codepage (RHBZ#1416405). It moves the `nss_compat` NSS service module to the main glibc package (RHBZ#1400538). As a security hardening measure, stdio streams are no longer flushed on process abort/assertion failure (RHBZ#1498880).
`/var/db/Makefile` is now included in the `nss_db` package (RHBZ#1498900). Fixes installation related failures for IBM z Series (RHBZ#1499260).

Two security fixes for the `glob` function are provided (CVE-2017-15670, CVE-2017-15671, RHBZ#1504807).

An error in the `sysconf` function which caused it to return -1 for `_SC_IOV_MAX` has been corrected (RHBZ#1504165).

The included upstream update from the glibc 2.26 stable branch improves C++ compatibility for ` <math.h>` functions and fixes a memory leak in malloc when thread local caches are in use.

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.


Update the affected glibc package.
