Fedora 27 : glibc (2017-0d3fdd3d1f)

High Nessus Plugin ID 105814

Synopsis

The remote Fedora host is missing a security update.

Description

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.

Solution

Update the affected glibc package.
