Description Aurelien Jarno 2015-03-08 20:46:14 UTC
ldconfig is using an aux-cache to speed up the ld.so.cache update. It is read by mmaping the file to a structure which contains data offsets used as pointers. As they are not checked, it is not hard to get ldconfig to segfault with a corrupted file. This happens for instance if the file is truncated, which is common following a filesystem check after system crash.

This can be reproduced for example by truncating the file to roughly half of it's size.

There is already in some code in elf/cache.c (load_aux_cache) to check for a corrupted aux cache, but it happens not to be enough.

Patch to fix that will follow on the mailing list.

commit 6a1cf708dd5681b517744d6d4fac02e4e4a0aa2e
Author: Aurelien Jarno <aurelien@aurel32.net>

    Fix ldconfig segmentation fault with corrupted cache (Bug 18093).
    ldconfig is using an aux-cache to speed up the ld.so.cache update. It
    is read by mmaping the file to a structure which contains data offsets
    used as pointers. As they are not checked, it is not hard to get
    ldconfig to segfault with a corrupted file. This happens for instance if
    the file is truncated, which is common following a filesystem check
    following a system crash.
    This can be reproduced for example by truncating the file to roughly
    half of it's size.
    There is already some code in elf/cache.c (load_aux_cache) to check
    for a corrupted aux cache, but it happens to be broken and not enough.
    The test (aux_cache->nlibs >= aux_cache_size) compares the number of
    libs entry with the cache size. It's a non sense, as it basically
    assumes that each library entry is a 1 byte... Instead this commit
    computes the theoretical cache size using the headers and compares it
    to the real size.

* Cache information can be queried via sysconf() function on s390 e.g. with
  _SC_LEVEL1_ICACHE_SIZE as argument.

* A buffer overflow in gethostbyname_r and related functions performing DNS
  requests has been fixed.  If the NSS functions were called with a
  misaligned buffer, the buffer length change due to pointer alignment was
  not taken into account.  This could result in application crashes or,
  potentially arbitrary code execution, using crafted, but syntactically
  valid DNS responses.  (CVE-2015-1781)

* The time zone file parser has been made more robust against crafted time
  zone files, avoiding heap buffer overflows related to the processing of
  the tzh_ttisstdcnt and tzh_ttisgmtcnt fields, and a stack overflow due to
  large time zone data files.  Overly long time zone specifiers in the TZ
  variable no longer result in stack overflows and crashes.

* A powerpc and powerpc64 optimization for TLS, similar to TLS descriptors
  for LD and GD on x86 and x86-64, has been implemented.  You will need
  binutils-2.24 or later to enable this optimization.

* Character encoding and ctype tables were updated to Unicode 7.0.0, using
  new generator scripts contributed by Pravin Satpute and Mike FABIAN (Red
  Hat).  These updates cause user visible changes, such as the fix for bug

* CVE-2014-8121 The NSS backends shared internal state between the getXXent
  and getXXbyYY NSS calls for the same database, causing a denial-of-service
  condition in some applications.

* Added vector math library named libmvec with the following vectorized x86_64
  implementations: cos, cosf, sin, sinf, sincos, sincosf, log, logf, exp, expf,
  pow, powf.
  The library can be disabled with --disable-mathvec. Use of the functions is
  enabled with -fopenmp -ffast-math starting from -O1 for GCC version >= 4.9.0.
  Shared library libmvec.so is linked in as needed when using -lm (no need to
  specify -lmvec explicitly for not static builds).
  Visit <https://sourceware.org/glibc/wiki/libmvec> for detailed information.

* A new fmemopen implementation has been added with the goal of POSIX
  compliance. The new implementation fixes the following long-standing
  issues: BZ#6544, BZ#11216, BZ#12836, BZ#13151, BZ#13152, and BZ#14292. The
  old implementation is still present for use be by existing binaries.

* The 32-bit sparc sigaction ABI was inadvertently broken in the 2.20 and 2.21
  releases.  It has been fixed to match 2.19 and older, but binaries built
  against 2.20 and 2.21 might need to be recompiled.  See BZ#18694.

* Port to Native Client running on ARMv7-A (--host=arm-nacl).

The GNU C Library

The GNU C Library version 2.29 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 2.29 release may be downloaded from:

The mirror list is at http://www.gnu.org/order/ftp.html

NEWS for version 2.29

* The getcpu wrapper function has been added, which returns the currently
  used CPU and NUMA node.  This function is Linux-specific.

* A new convenience target has been added for distribution maintainers
  to build and install all locales as directories with files.  The new
  target is run by issuing the following command in your build tree:
  'make localedata/install-locale-files', with an optional DESTDIR
  to set the install root if you wish to install into a non-default
  configured location.

* Optimized generic exp, exp2, log, log2, pow, sinf, cosf, sincosf and tanf.

* The reallocarray function is now declared under _DEFAULT_SOURCE, not just
  for _GNU_SOURCE, to match BSD environments.

* For powercp64le ABI, Transactional Lock Elision is now enabled iff kernel
  indicates that it will abort the transaction prior to entering the kernel
  (PPC_FEATURE2_HTM_NOSC on hwcap2).  On older kernels the transaction is
  suspended, and this caused some undefined side-effects issues by aborting
  transactions manually.  Glibc avoided it by abort transactions manually on
  each syscall, but it lead to performance issues on newer kernels where the
  HTM state is saved and restore lazily (the state being saved even when the
  process actually does not use HTM).

* The functions posix_spawn_file_actions_addchdir_np and
  posix_spawn_file_actions_addfchdir_np have been added, enabling
  posix_spawn and posix_spawnp to run the new process in a different
  directory.  These functions are GNU extensions.  The function
  posix_spawn_file_actions_addchdir_np is similar to the Solaris function
  of the same name.

* The popen and system do not run atfork handlers anymore (BZ#17490).
  Although it is a possible POSIX violation, the POSIX rationale in
  pthread_atfork documentation regarding atfork handlers is to handle
  inconsistent mutex state after a fork call in a multi-threaded process.
  In both popen and system there is no direct access to user-defined mutexes.

* Support for the C-SKY ABIV2 running on Linux has been added.  This port
  requires at least binutils-2.32, gcc-9.0, and linux-4.20.  Two ABIs are
    - C-SKY ABIV2 soft-float little-endian
    - C-SKY ABIV2 hard-float little-endian

* strftime's default formatting of a locale's alternative year (%Ey)
  has been changed to zero-pad the year to a minimum of two digits,
  like "%y".  This improves the display of Japanese era years during
  the first nine years of a new era, and is expected to be harmless
  for all other locales (only Japanese locales regularly have
  alternative year numbers less than 10).  Zero-padding can be
  overridden with the '_' or '-' flags (which are GNU extensions).

* As a GNU extension, the '_' and '-' flags can now be applied to
  "%EY" to control how the year number is formatted; they have the
  same effect that they would on "%Ey".

Deprecated and removed features, and other changes affecting compatibility:

* The glibc.tune tunable namespace has been renamed to glibc.cpu and the
  tunable glibc.tune.cpu has been renamed to glibc.cpu.name.

* The type of the pr_uid and pr_gid members of struct elf_prpsinfo, defined
  in <sys/procfs.h>, has been corrected to match the type actually used by
  the Linux kernel.  This affects the size and layout of that structure on
  MicroBlaze, MIPS (n64 ABI only), Nios II and RISC-V.

* For the MIPS n32 ABI, the type of the pr_sigpend and pr_sighold members of
  struct elf_prstatus, and the pr_flag member of struct elf_prpsinfo,
  defined in <sys/procfs.h>, has been corrected to match the type actually
  used by the Linux kernel.  This affects the size and layout of those

* An archaic GNU extension to scanf, under which '%as', '%aS', and '%a[...]'
  meant to scan a string and allocate space for it with malloc, is now
  restricted to programs compiled in C89 or C++98 mode with _GNU_SOURCE
  defined.  This extension conflicts with C99's use of '%a' to scan a
  hexadecimal floating-point number, which is now available to programs
  compiled as C99 or C++11 or higher, regardless of _GNU_SOURCE.

  POSIX.1-2008 includes the feature of allocating a buffer for string input
  with malloc, using the modifier letter 'm' instead.  Programs using
  '%as', '%aS', or '%a[...]' with the old GNU meaning should change to
  '%ms', '%mS', or '%m[...]' respectively.  Programs that wish to use the
  C99 '%a' no longer need to avoid _GNU_SOURCE.

  GCC's -Wformat warnings can detect most uses of this extension, as long
  as all functions that call vscanf, vfscanf, or vsscanf are annotated with
  __attribute__ ((format (scanf, ...))).

Changes to build and runtime requirements:

* Python 3.4 or later is required to build the GNU C Library.

* On most architectures, GCC 5 or later is required to build the GNU C
  Library.  (On powerpc64le, GCC 6.2 or later is still required, as before.)

  Older GCC versions and non-GNU compilers are still supported when
  compiling programs that use the GNU C Library.

Security related changes:

  CVE-2018-19591: A file descriptor leak in if_nametoindex can lead to a
  denial of service due to resource exhaustion when processing getaddrinfo
  calls with crafted host names.  Reported by Guido Vranken.

  CVE-2019-6488: On x32, the size_t parameter may be passed in the lower
  32 bits of a 64-bit register with with non-zero upper 32 bit.  When it
  happened, accessing the 32-bit size_t value as the full 64-bit register
  in the assembly string/memory functions would cause a buffer overflow.
  Reported by H.J. Lu.

  CVE-2016-10739: The getaddrinfo function could successfully parse IPv4
  addresses with arbitrary trailing characters, potentially leading to data
  or command injection issues in applications.
