Name        : glibc
Product     : Fedora 22
Version     : 2.21
Release     : 11.fc22
URL         : http://www.gnu.org/software/glibc/
Summary     : The GNU libc libraries
Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.

Update Information:

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).
