The GNU C Library ================= The GNU C Library version 2.19 is now available. The GNU C Library is used as *the* C library in the GNU systems and most systems with the Linux kernel. The GNU C Library is primarily designed to be a portable and high performance C library. It follows all relevant standards including ISO C11 and POSIX.1-2008. It is also internationalized and has one of the most complete internationalization interfaces known. The GNU C Library webpage is at http://www.gnu.org/software/libc/ Packages for the 2.19 release may be downloaded from: http://ftpmirror.gnu.org/libc/ http://ftp.gnu.org/gnu/libc/ The mirror list is at http://www.gnu.org/order/ftp.html NEWS for version 2.19 ===================== * The following bugs are resolved with this release: 156, 387, 431, 762, 832, 926, 2801, 4772, 6786, 6787, 6807, 6810, 6981, 7003, 9721, 9954, 10253, 10278, 11087, 11157, 11214, 12100, 12486, 12751, 12986, 13028, 13982, 13985, 14029, 14032, 14120, 14143, 14155, 14286, 14547, 14699, 14752, 14782, 14876, 14910, 15004, 15048, 15073, 15089, 15128, 15218, 15268, 15277, 15308, 15362, 15374, 15400, 15425, 15427, 15483, 15522, 15531, 15532, 15593, 15601, 15608, 15609, 15610, 15632, 15640, 15670, 15672, 15680, 15681, 15723, 15734, 15735, 15736, 15748, 15749, 15754, 15760, 15763, 15764, 15797, 15799, 15825, 15843, 15844, 15846, 15847, 15849, 15850, 15855, 15856, 15857, 15859, 15867, 15886, 15887, 15890, 15892, 15893, 15895, 15897, 15901, 15905, 15909, 15915, 15917, 15919, 15921, 15923, 15939, 15941, 15948, 15963, 15966, 15968, 15985, 15988, 15997, 16032, 16034, 16036, 16037, 16038, 16041, 16046, 16055, 16071, 16072, 16074, 16077, 16078, 16103, 16112, 16143, 16144, 16146, 16150, 16151, 16153, 16167, 16169, 16172, 16195, 16214, 16245, 16271, 16274, 16283, 16289, 16293, 16314, 16316, 16330, 16337, 16338, 16356, 16365, 16366, 16369, 16372, 16375, 16379, 16384, 16385, 16386, 16387, 16390, 16394, 16398, 16400, 16407, 16408, 16414, 16430, 16431, 16453, 16474, 16506, 16510, 16529 * 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.
