"This updates addresses a critical security vulnerability in the DNS
resolver related to `AF_UNSPEC` queries with `getaddrinfo`
(CVE-2015-7547). It also includes security fixes for CVE-2015-8777 and
CVE-2015-1781. It improves `malloc` scalability for applications which
start and terminate many threads. The output of `locale -a` is now
ASCII-only (previously, it contained ISO-8859-1 characters).

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