* Slovenian translations for glibc messages have been contributed by the
Translation Project's Slovenian team of translators.
* The public headers no longer use __unused nor __block. This change is to
support compiling programs that are derived from BSD sources and use
__unused internally, and to support compiling with Clang's -fblock
extension which uses __block.
* CVE-2012-4412 The strcoll implementation caches indices and rules for
large collation sequences to optimize multiple passes. This cache
computation may overflow for large collation sequences and may cause a
stack or buffer overflow. This is now fixed to use a slower algorithm
which does not use a cache if there is an integer overflow.
* CVE-2012-4424 The strcoll implementation uses malloc to cache indices and
rules for large collation sequences to optimize multiple passes and falls
back to alloca if malloc fails, resulting in a possible stack overflow.
The implementation now falls back to an uncached collation sequence lookup
if malloc fails.
* CVE-2013-4788 The pointer guard used for pointer mangling was not
initialized for static applications resulting in the security feature
being disabled. The pointer guard is now correctly initialized to a
random value for static applications. Existing static applications need
to be recompiled to take advantage of the fix (bug 15754).
* CVE-2013-4237 The readdir_r function could write more than NAME_MAX bytes
to the d_name member of struct dirent, or omit the terminating NUL
character. (Bugzilla #14699).
* CVE-2013-4332 The pvalloc, valloc, memalign, posix_memalign and
aligned_alloc functions could allocate too few bytes or corrupt the
heap when passed very large allocation size values (Bugzilla #15855,
#15856, #15857).
* CVE-2013-4458 Stack overflow in getaddrinfo with large number of results
for AF_INET6 has been fixed (Bugzilla #16072).
* New locales: ak_GH, anp_IN, ar_SS, cmn_TW, hak_TW, lzh_TW, nan_TW, pap_AW,
pap_CW, quz_PE, the_NP.
* Substantially revised locales: gd_GB, ht_HT
* The LC_ADDRESS field was updated to support country_car for almost all
supported locales.
* ISO 1427 definitions were updated.
* ISO 3166 definitions were updated.
* The localedef utility now supports --big-endian and --little-endian
command-line options to generate locales for a different system from that
for which the C library was built.
* Binary locale files now only depend on the endianness of the system for
which they are generated and not on other properties of that system. As a
consequence, binary files generated with new localedef may be incompatible
with old versions of the GNU C Library, and binary files generated with
old localedef may be incompatible with this version of the GNU C Library,
in the following circumstances:
+ Locale files may be incompatible on m68k systems.
+ Locale archive files (but not separate files for individual locales) may
be incompatible on systems where plain "char" is signed.
* The configure option --disable-versioning has been removed. Builds with
--disable-versioning had not worked for several years.
* ISO 639 definitions were updated for Chiga (cgg) and Chinese (gan, hak, czh,
cjy, lzh, cmn, mnp, cdo, czo, cpx, wuu, hsn, yue).
* SystemTap probes for malloc have been introduced.
* SystemTap probes for slow multiple precision fallback paths of
transcendental functions have been introduced.
* Support for powerpc64le has been added.
* The soft-float powerpc port now supports e500 processors.
* Support for STT_GNU_IFUNC symbols added for ppc32/power4+ and ppc64.
* A new feature test macro _DEFAULT_SOURCE is available to enable the same
set of header declarations that are enabled by default, even when other
feature test macros or compiler options such as -std=c99 would otherwise
disable some of those declarations.
* The _BSD_SOURCE feature test macro no longer enables BSD interfaces that
conflict with POSIX. The libbsd-compat library (which was a dummy library
that did nothing) has also been removed.
* Preliminary documentation about Multi-Thread, Async-Signal and
Async-Cancel Safety has been added.
