Name        : glibc
Product     : Fedora 23
Version     : 2.22
Release     : 5.fc23
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:

An invalid optimization in strcoll resulted in incorrect sorting for languages
that contained digraphs. The invalid optimization has been removed and the
correct sorting restored to languages with digraphs e.g. cs_CZ and da_DK.
(#1276711)  A defect in the malloc implementation, present since glibc 2.15
(2012) or glibc 2.10 via --enable-experimental-malloc (2009), could result in
the unnecessary serialization of memory allocation requests across threads.  The
defect is now corrected.  Users should see a substantial increase in  the
concurrent throughput of allocation requests for applications which trigger this
bug.  Affected applications typically create create and destroy threads
frequently (#1279673).
