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. (CVE-2015-7547)
