<summary>Security update for python-cffi, python-cryptography</summary>
<description>This update for python-cffi, python-cryptography fixes the following issues:
Security issue fixed:
- CVE-2018-10903: Fixed GCM tag forgery via truncated tag in finalize_with_tag API (bsc#1101820).
Non-security issues fixed:
python-cffi was updated to 1.11.2 (bsc#1138748, jsc#ECO-1256, jsc#PM-1598):
- fixed a build failure on i586 (bsc#1111657)
- Salt was unable to highstate in snapshot 20171129 (bsc#1070737)
- Update pytest in spec to add c directory tests in addition to
testing directory.
- update to version 1.11.2:
* Fix Windows issue with managing the thread-state on CPython 3.0 to
3.5
- Update pytest in spec to add c directory tests in addition to
testing directory.
- Omit test_init_once_multithread tests as they rely on multiple
threads finishing in a given time. Returns sporadic pass/fail
within build.
- Update to 1.11.1:
* Fix tests, remove deprecated C API usage
* Fix (hack) for 3.6.0/3.6.1/3.6.2 giving incompatible binary
extensions (cpython issue #29943)
* Fix for 3.7.0a1+
- Update to 1.11.0:
* Support the modern standard types char16_t and char32_t. These
work like wchar_t: they represent one unicode character, or when
used as charN_t * or charN_t[] they represent a unicode string.
The difference with wchar_t is that they have a known, fixed
size. They should work at all places that used to work with
wchar_t (please report an issue if I missed something). Note
that with set_source(), you need to make sure that these types
are actually defined by the C source you provide (if used in
cdef()).
* Support the C99 types float _Complex and double _Complex. Note
that libffi doesn't support them, which means that in the ABI
mode you still cannot call C functions that take complex
numbers directly as arguments or return type.
* Fixed a rare race condition when creating multiple FFI instances
from multiple threads. (Note that you aren't meant to create
many FFI instances: in inline mode, you should write
ffi = cffi.FFI() at module level just after import cffi; and in
out-of-line mode you don't instantiate FFI explicitly at all.)
* Windows: using callbacks can be messy because the CFFI internal
error messages show up to stderr-but stderr goes nowhere in many
applications. This makes it particularly hard to get started
with the embedding mode. (Once you get started, you can at least
use @ffi.def_extern(onerror=...) and send the error logs where
it makes sense for your application, or record them in log
files, and so on.) So what is new in CFFI is that now, on
Windows CFFI will try to open a non-modal MessageBox (in addition
to sending raw messages to stderr). The MessageBox is only
visible if the process stays alive: typically, console
applications that crash close immediately, but that is also the
situation where stderr should be visible anyway.
* Progress on support for callbacks in NetBSD.
* Functions returning booleans would in some case still return 0
or 1 instead of False or True. Fixed.
* ffi.gc() now takes an optional third parameter, which gives an
estimate of the size (in bytes) of the object. So far, this is
only used by PyPy, to make the next GC occur more quickly
(issue #320). In the future, this might have an effect on
CPython too (provided the CPython issue 31105 is addressed).
* Add a note to the documentation: the ABI mode gives function
objects that are slower to call than the API mode does. For
some reason it is often thought to be faster. It is not!
- Update to 1.10.1:
* Fixed the line numbers reported in case of cdef() errors. Also,
I just noticed, but pycparser always supported the preprocessor
directive # 42 "foo.h" to mean "from the next line, we're in
file foo.h starting from line 42";, which it puts in the error
messages.
- update to 1.10.0:
* Issue #295: use calloc() directly instead of PyObject_Malloc()+memset()
to handle ffi.new() with a default allocator. Speeds up ffi.new(large-array)
where most of the time you never touch most of the array.
* Some OS/X build fixes ("only with Xcode but without CLT";).
* Improve a couple of error messages: when getting mismatched versions of
cffi and its backend; and when calling functions which cannot be called with
libffi because an argument is a struct that is "too complicated"; (and not
a struct pointer, which always works).
* Add support for some unusual compilers (non-msvc, non-gcc, non-icc, non-clang)
* Implemented the remaining cases for ffi.from_buffer. Now all
buffer/memoryview objects can be passed. The one remaining check is against
passing unicode strings in Python 2. (They support the buffer interface, but
that gives the raw bytes behind the UTF16/UCS4 storage, which is most of the
times not what you expect. In Python 3 this has been fixed and the unicode
strings don't support the memoryview interface any more.)
* The C type _Bool or bool now converts to a Python boolean when reading,
instead of the content of the byte as an integer. The potential
incompatibility here is what occurs if the byte contains a value different
from 0 and 1. Previously, it would just return it; with this change, CFFI
raises an exception in this case. But this case means "undefined behavior";
in C; if you really have to interface with a library relying on this,
don't use bool in the CFFI side. Also, it is still valid to use a byte
string as initializer for a bool[], but now it must only contain \x00 or
\x01. As an aside, ffi.string() no longer works on bool[] (but it never made
much sense, as this function stops at the first zero).
* ffi.buffer is now the name of cffi's buffer type, and ffi.buffer() works
like before but is the constructor of that type.
* ffi.addressof(lib, "name") now works also in in-line mode, not only in
out-of-line mode. This is useful for taking the address of global variables.
* Issue #255: cdata objects of a primitive type (integers, floats, char) are
now compared and ordered by value. For example, <cdata 'int' 42> compares
equal to 42 and <cdata 'char' b'A'> compares equal to b'A'. Unlike C,
<cdata 'int' -1> does not compare equal to ffi.cast("unsigned int", -1): it
compares smaller, because -1 < 4294967295.
* PyPy: ffi.new() and ffi.new_allocator()() did not record "memory pressure";,
causing the GC to run too infrequently if you call ffi.new() very often
and/or with large arrays. Fixed in PyPy 5.7.
* Support in ffi.cdef() for numeric expressions with + or -. Assumes that
there is no overflow; it should be fixed first before we add more general
support for arbitrary arithmetic on constants.
- do not generate HTML documentation for packages that are indirect
dependencies of Sphinx
(see docs at https://cffi.readthedocs.org/ )
- update to 1.9.1
- Structs with variable-sized arrays as their last field: now we track the
length of the array after ffi.new() is called, just like we always tracked
the length of ffi.new("int[]", 42). This lets us detect out-of-range
accesses to array items. This also lets us display a better repr(), and
have the total size returned by ffi.sizeof() and ffi.buffer(). Previously
both functions would return a result based on the size of the declared
structure type, with an assumed empty array. (Thanks andrew for starting
this refactoring.)
- Add support in cdef()/set_source() for unspecified-length arrays in
typedefs: typedef int foo_t[...];. It was already supported for global
variables or structure fields.
- I turned in v1.8 a warning from cffi/model.py into an error: 'enum xxx' has
no values explicitly defined: refusing to guess which integer type it is
meant to be (unsigned/signed, int/long). Now I'm turning it back to a
warning again; it seems that guessing that the enum has size int is a
99%-safe bet. (But not 100%, so it stays as a warning.)
- Fix leaks in the code handling FILE * arguments. In CPython 3 there is a
remaining issue that is hard to fix: if you pass a Python file object to a
FILE * argument, then os.dup() is used and the new file descriptor is only
closed when the GC reclaims the Python file object-and not at the earlier
time when you call close(), which only closes the original file descriptor.
If this is an issue, you should avoid this automatic convertion of Python
file objects: instead, explicitly manipulate file descriptors and call
fdopen() from C (...via cffi).
- When passing a void * argument to a function with a different pointer type,
or vice-versa, the cast occurs automatically, like in C. The same occurs
for initialization with ffi.new() and a few other places. However, I
thought that char * had the same property-but I was mistaken. In C you get
the usual warning if you try to give a char * to a char ** argument, for
example. Sorry about the confusion. This has been fixed in CFFI by giving
for now a warning, too. It will turn into an error in a future version.
- Issue #283: fixed ffi.new() on structures/unions with nested anonymous
structures/unions, when there is at least one union in the mix. When
initialized with a list or a dict, it should now behave more closely like
the { } syntax does in GCC.
- CPython 3.x: experimental: the generated C extension modules now use the
"limited API";, which means that, as a compiled .so/.dll, it should work
directly on any version of CPython >= 3.2. The name produced by distutils
is still version-specific. To get the version-independent name, you can
rename it manually to NAME.abi3.so, or use the very recent setuptools 26.
- Added ffi.compile(debug=...), similar to python setup.py build --debug but
defaulting to True if we are running a debugging version of Python itself.
- Removed the restriction that ffi.from_buffer() cannot be used on byte
strings. Now you can get a char * out of a byte string, which is valid as
long as the string object is kept alive. (But don't use it to modify the
string object! If you need this, use bytearray or other official
techniques.)
- PyPy 5.4 can now pass a byte string directly to a char * argument (in older
versions, a copy would be made). This used to be a CPython-only
optimization.
- ffi.gc(p, None) removes the destructor on an object previously created by
another call to ffi.gc()
- bool(ffi.cast("primitive type", x)) now returns False if the value is zero
(including -0.0), and True otherwise. Previously this would only return
False for cdata objects of a pointer type when the pointer is NULL.
- bytearrays: ffi.from_buffer(bytearray-object) is now supported. (The reason
it was not supported was that it was hard to do in PyPy, but it works since
PyPy 5.3.) To call a C function with a char * argument from a buffer
object-now including bytearrays-you write lib.foo(ffi.from_buffer(x)).
Additionally, this is now supported: p[0:length] = bytearray-object. The
problem with this was that a iterating over bytearrays gives numbers
instead of characters. (Now it is implemented with just a memcpy, of
course, not actually iterating over the characters.)
- C++: compiling the generated C code with C++ was supposed to work, but
failed if you make use the bool type (because that is rendered as the C
_Bool type, which doesn't exist in C++).
- help(lib) and help(lib.myfunc) now give useful information, as well as
dir(p) where p is a struct or pointer-to-struct.
- update for multipython build
- disable "negative left shift" warning in test suite to prevent
failures with gcc6, until upstream fixes the undefined code
in question (bsc#981848)
- Update to version 1.6.0:
* ffi.list_types()
* ffi.unpack()
* extern "Python+C";
* in API mode, lib.foo.__doc__ contains the C signature now.
* Yet another attempt at robustness of ffi.def_extern() against
CPython's interpreter shutdown logic.
- Update in SLE-12 (bsc#1138748, jsc#ECO-1256, jsc#PM-1598)
- Make this version of the package compatible with OpenSSL 1.1.1d, thus fixing bsc#1149792.
- bsc#1101820 CVE-2018-10903 GCM tag forgery via truncated tag in
finalize_with_tag API
- Add proper conditional for the python2, the ifpython works only
for the requires/etc
- add missing dependency on python ssl
- update to version 2.1.4:
* Added X509_up_ref for an upcoming pyOpenSSL release.
- update to version 2.1.3:
* Updated Windows, macOS, and manylinux1 wheels to be compiled with
OpenSSL 1.1.0g.
