- Update to glibc 2.17.90 85891acadf1b:
* CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
has been fixed by disabling the use of pt_chown (Bugzilla #15755).
Distributions can re-enable building and using pt_chown via the new configure
option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
considerable security risks and should only be used if the distribution
understands and accepts the risks.
* CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
#15078).
* CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
fixed (Bugzilla #15330).
* Add support for calling C++11 thread_local object destructors on thread
and program exit. This needs compiler support for offloading C++11
destructor calls to glibc.
* Improved worst case performance of libm functions with double inputs and
output.
* Support for priority inherited mutexes in pthread condition variables on
non-x86 architectures.
* Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
* Optimized string functions for ARM. Implemented by Will Newton and
Richard Henderson.
* Added a benchmark framework to track performance of functions in glibc.
* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
It is based on draft TS 18661 and currently enabled as a GNU extension.
* On Linux, the clock function now uses the clock_gettime system call
for improved precision, rather than old times system call.
* Added new API functions pthread_getattr_default_np and
pthread_setattr_default_np to get and set the default pthread
attributes of a process.
* Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
