The patch for bug 16071 broke parsing of files where a line doesn't fit in the supplied buffer, by ignoring such lines instead of returning ERANGE to the caller.

The annotated tag, glibc-2.20 has been created at 9bcede1abfb0fa62d54b7cfce5c72d56e2f7b95c (tag) tagging b8079dd0d360648e4e8de48656c5c38972621072 (commit) replaces glibc-2.19 tagged by Allan McRae on Sun Sep 7 18:17:29 2014 +1000 - Log ----------------------------------------------------------------- The GNU C Library ================= The GNU C Library version 2.20 is now available. The GNU C Library is used as *the* C library in the GNU systems and is widely used on 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 2.20 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 2.20 ==================== * The following bugs are resolved with this release: 6804, 9894, 12994, 13347, 13651, 14308, 14770, 15119, 15132, 15347, 15514, 15698, 15804, 15894, 15946, 16002, 16064, 16095, 16194, 16198, 16275, 16284, 16287, 16315, 16348, 16349, 16354, 16357, 16362, 16447, 16516, 16532, 16539, 16545, 16561, 16562, 16564, 16574, 16599, 16600, 16609, 16610, 16611, 16613, 16619, 16623, 16629, 16632, 16634, 16639, 16642, 16648, 16649, 16670, 16674, 16677, 16680, 16681, 16683, 16689, 16695, 16701, 16706, 16707, 16712, 16713, 16714, 16724, 16731, 16739, 16740, 16743, 16754, 16758, 16759, 16760, 16770, 16786, 16789, 16791, 16796, 16799, 16800, 16815, 16823, 16824, 16831, 16838, 16839, 16849, 16854, 16876, 16877, 16878, 16882, 16885, 16888, 16890, 16892, 16912, 16915, 16916, 16917, 16918, 16922, 16927, 16928, 16932, 16943, 16958, 16965, 16966, 16967, 16977, 16978, 16984, 16990, 16996, 17009, 17022, 17031, 17042, 17048, 17050, 17058, 17061, 17062, 17069, 17075, 17078, 17079, 17084, 17086, 17088, 17092, 17097, 17125, 17135, 17137, 17150, 17153, 17187, 17213, 17259, 17261, 17262, 17263, 17319, 17325, 17354. * Reverted change of ABI data structures for s390 and s390x: On s390 and s390x the size of struct ucontext and jmp_buf was increased in 2.19. This change is reverted in 2.20. The introduced 2.19 symbol versions of getcontext, setjmp, _setjmp, __sigsetjmp, longjmp, _longjmp, siglongjmp are preserved pointing straight to the same implementation as the old ones. Given that, new callers will simply provide a too-big buffer to these functions. Any applications/libraries out there that embed jmp_buf or ucontext_t in an ABI-relevant data structure that have already been rebuilt against 2.19 headers will have to rebuilt again. This is necessary in any case to revert the breakage in their ABI caused by the glibc change. * Support for file description locks is added to systems running the Linux kernel. The standard file locking interfaces are extended to operate on file descriptions, not file descriptors, via the use of F_OFD_GETLK, F_OFD_SETLK, and F_OFD_SETLKW. File description locks are associated with an open file instead of a process. * Optimized strchr implementation for AArch64. Contributed by ARM Ltd. * The minimum Linux kernel version that this version of the GNU C Library can be used with is 2.6.32. * Running the testsuite no longer terminates as soon as a test fails. Instead, a file tests.sum (xtests.sum from "make xcheck") is generated, with PASS or FAIL lines for individual tests. A summary of the results is printed, including a list of failing lists, and "make check" exits with error status if there were any unexpected failures. "make check stop-on-test-failure=y" may be used to keep the old behavior. * The am33 port, which had not worked for several years, has been removed from ports. * The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer supported; they now act the same as _DEFAULT_SOURCE (but generate a warning). Except for cases where _BSD_SOURCE enabled BSD interfaces that conflicted with POSIX (support for which was removed in 2.19), the interfaces those macros enabled remain available when compiling with _GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature test macros defined. * Optimized strcmp implementation for ARMv7. Contributed by ARM Ltd. * Added support for TX lock elision of pthread mutexes on s390 and s390x. This may improve lock scaling of existing programs on TX capable systems. The lock elision code is only built with --enable-lock-elision=yes and then requires a GCC version supporting the TX builtins. With lock elision default mutexes are elided via __builtin_tbegin, if the cpu supports transactions. By default lock elision is not enabled and the elision code is not built. * CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not copy the path argument. This allowed programs to cause posix_spawn to deference a dangling pointer, or use an unexpected pathname argument if the string was modified after the posix_spawn_file_actions_addopen invocation. * All supported architectures now use the main glibc sysdeps directory instead of some being in a separate "ports" directory (which was distributed separately before glibc 2.17). * The NPTL implementation of POSIX pthreads is no longer an "add-on". On configurations that support it (all Linux configurations), it's now used regardless of the --enable-add-ons switch to configure. It is no longer possible to build such configurations without pthreads support. * Locale names, including those obtained from environment variables (LANG and the LC_* variables), are more tightly checked for proper syntax. setlocale will now fail (with EINVAL) for locale names that are overly long, contain slashes without starting with a slash, or contain ".." path components. (CVE-2014-0475) Previously, some valid locale names were silently replaced with the "C" locale when running in AT_SECURE mode (e.g., in a SUID program). This is no longer necessary because of the additional checks. * On x86-64, the dynamic linker's lazy-binding support is now compatible with application code using Intel MPX instructions. (With all previous versions, the MPX register state could be clobbered when making calls into or out of a shared library.) Note that while the new dynamic linker is compatible with all known x86 hardware whether or not it supports Intel MPX, some x86 instruction-set emulators might fail to handle the new instruction encodings. This is known to affect Valgrind versions up through 3.9 (but will be fixed in the forthcoming 3.10 release), and might affect other tools that do instruction emulation. * Support for loadable gconv transliteration modules has been removed. The support for transliteration modules has been non-functional for over a decade, and the removal is prompted by security defects. The normal gconv conversion modules are still supported. Transliteration with //TRANSLIT is still possible, and the //IGNORE specifier continues to be supported. (CVE-2014-5119) * Decoding a crafted input sequence in the character sets IBM933, IBM935, IBM937, IBM939, IBM1364 could result in an out-of-bounds array read, resulting a denial-of-service security vulnerability in applications which use functions related to iconv.

The description is misleading. This bug can theoretically result in applications receiving wrong data from NSS, and the data could even be attacker-controlled, which means that this is a security bug. Introduced in glibc 2.19, fixed in 2.20. The broken fix which went into glibc 2.19 has been backported to earlier glibc versions by some distributions.

This is not quite correct, either. This is actually a heap-based buffer overflow.

This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "GNU C Library master sources". The annotated tag, glibc-2.23 has been created at 10ed3a0ffbb43ce0b0739da4addc747733be5e63 (tag) tagging ab30899d880f9741a409cbc0d7a28399bdac21bf (commit) replaces glibc-2.22 tagged by Adhemerval Zanella on Thu Feb 18 16:04:58 2016 -0200 - Log ----------------------------------------------------------------- The GNU C Library ================= The GNU C Library version 2.23 is now available. The GNU C Library is used as *the* C library in the GNU system and in GNU/Linux systems, as well as many other systems that use Linux as the 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 2.23 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 2.23 ===================== * Unicode 8.0.0 Support: Character encoding, character type info, and transliteration tables are all updated to Unicode 8.0.0, using new and/or improved generator scripts contributed by Mike FABIAN (Red Hat). These updates cause user visible changes, such as the fixes for bugs 89, 16061, and 18568. * sched_setaffinity, pthread_setaffinity_np no longer attempt to guess the kernel-internal CPU set size. This means that requests that change the CPU affinity which failed before (for example, an all-ones CPU mask) will now succeed. Applications that need to determine the effective CPU affinities need to call sched_getaffinity or pthread_getaffinity_np after setting it because the kernel can adjust it (and the previous size check would not detect this in the majority of cases). * The fts.h header can now be used with -D_FILE_OFFSET_BITS=64. With LFS the following new symbols are used: fts64_children, fts64_close, fts64_open, fts64_read and fts64_set. * getaddrinfo now detects certain invalid responses on an internal netlink socket. If such responses are received, an affected process will terminate with an error message of "Unexpected error <number> on netlink descriptor <number>" or "Unexpected netlink response of size <number> on descriptor <number>". The most likely cause for these errors is a multi-threaded application which erroneously closes and reuses the netlink file descriptor while it is used by getaddrinfo. * 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 concurent throughput of allocation requests for applications which trigger this bug. Affected applications typically create create and destroy threads frequently. (Bug 19048 was reported and analyzed by Ericsson.) * There is now a --disable-timezone-tools configure option for disabling the building and installing of the timezone related utilities (zic, zdump, and tzselect). This is useful for people who build the timezone data and code independent of the GNU C Library. * The obsolete header <regexp.h> has been removed. Programs that require this header must be updated to use <regex.h> instead. * The obsolete functions bdflush, create_module, get_kernel_syms, query_module and uselib are no longer available to newly linked binaries; the header <sys/kdaemon.h> has been removed. These functions and header were specific to systems using the Linux kernel and could not usefully be used with the GNU C Library on systems with version 2.6 or later of the Linux kernel. * Optimized string, wcsmbs and memory functions for IBM z13. Implemented by Stefan Liebler. * Newly linked programs that define a variable called signgam will no longer have it set by the lgamma, lgammaf and lgammal functions. Programs that require signgam to be set by those functions must ensure that they use the variable provided by the GNU C Library and declared in <math.h>, without defining their own copy. * The minimum GCC version that can be used to build this version of the GNU C Library is GCC 4.7. Older GCC versions, and non-GNU compilers, can still be used to compile programs using the GNU C Library. Security related changes: * An out-of-bounds value in a broken-out struct tm argument to strftime no longer causes a crash. Reported by Adam Nielsen. (CVE-2015-8776) * The LD_POINTER_GUARD environment variable can no longer be used to disable the pointer guard feature. It is always enabled. Previously, LD_POINTER_GUARD could be used to disable security hardening in binaries running in privileged AT_SECURE mode. Reported by Hector Marco-Gisbert. (CVE-2015-8777) * An integer overflow in hcreate and hcreate_r could lead to an out-of-bounds memory access. Reported by Szabolcs Nagy. (CVE-2015-8778) * The catopen function no longer has unbounded stack usage. Reported by Max. (CVE-2015-8779) * The nan, nanf and nanl functions no longer have unbounded stack usage depending on the length of the string passed as an argument to the functions. Reported by Joseph Myers. (CVE-2014-9761) * A stack-based buffer overflow was found in libresolv when invoked from libnss_dns, allowing specially crafted DNS responses to seize control of execution flow in the DNS client. The buffer overflow occurs in the functions send_dg (send datagram) and send_vc (send TCP) for the NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC family. The use of AF_UNSPEC triggers the low-level resolver code to send out two parallel queries for A and AAAA. A mismanagement of the buffers used for those queries could result in the response of a query writing beyond the alloca allocated buffer created by _nss_dns_gethostbyname4_r. Buffer management is simplified to remove the overflow. Thanks to the Google Security Team and Red Hat for reporting the security impact of this issue, and Robert Holiday of Ciena for reporting the related bug 18665.
