glibc-2.12-1.166.AXS4.7

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.

Security issues fixed with this release:

CVE-2015-7547
** RESERVED **
This candidate has been reserved by an organization or individual that
will use it when announcing a new security problem. When the
candidate has been publicized, the details for this candidate will be
provided.

Fixed bugs:

* The dynamic loader has been enhanced to allow the loading of more shared libraries that make use of static thread local storage. While static thread local storage is the fastest access mechanism it may also prevent the shared library from being loaded at all since the static storage space is a limited and shared process-global resource. Applications which would previously fail with "dlopen: cannot load any more object with static TLS" should now start up correctly.
* A bug in the POSIX realtime support would cause asynchronous I/O or certain timer API calls to fail and return errors in the presence of large thread-local storage data that exceeded PTHREAD_STACK_MIN in size (generally 16 KiB). The bug in librt has been corrected and the impacted APIs no longer return errors when large thread-local storage data is present in the application.
