-Subject: [PATCH] bin/automake: escape '{' in regexp pattern
-
-Based on perlre(1) documentation:
-.. in Perl v5.26, literal uses of a curly bracket will be required
-to be escaped, say by preceding them with a backslash ("\{" ) or
-enclosing them within square brackets ("[{]") ..
-
-References:
-https://bugzilla.redhat.com/1239379
-
-* bin/automake.in (substitute_ac_subst_variables): Escape the
-occurrence of '{' character.

-      * tests/misc/cut-huge-range.sh: On some systems returns_ may
-      use more memory, so incorporate that in the determination
-      of the ulimit value to use.  Noticed on ARMv7 with bash-4.4.12,

-
-When using the "DELAYBIND" feature, it turns out that .eqproc can be called with
-parameters that are not both procedures. In this case, it turns out, the
-expectation is for the operator to return 'false', rather than throw an error.

-Subject: [PATCH] Disallow namespace nodes in XPointer ranges
-
-Namespace nodes must be copied to avoid use-after-free errors.
-But they don't necessarily have a physical representation in a
-document, so simply disallow them in XPointer ranges.
-
-Found with afl-fuzz.
-
-Fixes CVE-2016-4658.

-Subject: [PATCH] Fix XPointer paths beginning with range-to
-
-The old code would invoke the broken xmlXPtrRangeToFunction. range-to
-isn't really a function but a special kind of location step. Remove
-this function and always handle range-to in the XPath code.
-
-The old xmlXPtrRangeToFunction could also be abused to trigger a
-use-after-free error with the potential for remote code execution.
-
-Found with afl-fuzz.
-
-Fixes CVE-2016-5131.

-Subject: [PATCH] Fix handling of parameter-entity references
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-There were two bugs where parameter-entity references could lead to an
-unexpected change of the input buffer in xmlParseNameComplex and
-xmlDictLookup being called with an invalid pointer.
-
-Percent sign in DTD Names
-=========================
-
-The NEXTL macro used to call xmlParserHandlePEReference. When parsing
-"complex" names inside the DTD, this could result in entity expansion
-which created a new input buffer. The fix is to simply remove the call
-to xmlParserHandlePEReference from the NEXTL macro. This is safe because
-no users of the macro require expansion of parameter entities.
-
-- xmlParseNameComplex
-- xmlParseNCNameComplex
-- xmlParseNmtoken
-
-The percent sign is not allowed in names, which are grammatical tokens.
-
-- xmlParseEntityValue
-
-Parameter-entity references in entity values are expanded but this
-happens in a separate step in this function.
-
-- xmlParseSystemLiteral
-
-Parameter-entity references are ignored in the system literal.
-
-- xmlParseAttValueComplex
-- xmlParseCharDataComplex
-- xmlParseCommentComplex
-- xmlParsePI
-- xmlParseCDSect
-
-Parameter-entity references are ignored outside the DTD.
-
-- xmlLoadEntityContent
-
-This function is only called from xmlStringLenDecodeEntities and
-entities are replaced in a separate step immediately after the function
-call.
-
-This bug could also be triggered with an internal subset and double
-entity expansion.
-
-This fixes bug 766956 initially reported by Wei Lei and independently by
-Chromium's ClusterFuzz, Hanno Böck, and Marco Grassi. Thanks to everyone
-involved.
-
-xmlParseNameComplex with XML_PARSE_OLD10
-========================================
-
-When parsing Names inside an expanded parameter entity with the
-XML_PARSE_OLD10 option, xmlParseNameComplex would call xmlGROW via the
-GROW macro if the input buffer was exhausted. At the end of the
-parameter entity's replacement text, this function would then call
-xmlPopInput which invalidated the input buffer.
-
-There should be no need to invoke GROW in this situation because the
-buffer is grown periodically every XML_PARSER_CHUNK_SIZE characters and,
-at least for UTF-8, in xmlCurrentChar. This also matches the code path
-executed when XML_PARSE_OLD10 is not set.
-
-This fixes bugs 781205 (CVE-2017-9049) and 781361 (CVE-2017-9050).
-Thanks to Marcel Böhme and Thuan Pham for the report.
-
-Additional hardening
-====================
-
-A separate check was added in xmlParseNameComplex to validate the
-buffer size.

-Subject: [PATCH] Don't use getentropy() on Linux
-
-Issue #29188: Support glibc 2.24 on Linux: don't use getentropy() function but
-read from /dev/urandom to get random bytes, for example in os.urandom().  On
-Linux, getentropy() is implemented which getrandom() is blocking mode, whereas
-os.urandom() should not block.

-Copy and then adapt Python/random.c from default branch. Difference between 3.5

-* Python 3.5 only uses getrandom() in non-blocking mode: flags=GRND_NONBLOCK
-* If getrandom() fails with EAGAIN: py_getrandom() immediately fails and
-  remembers that getrandom() doesn't work.
-* Python 3.5 has no _PyOS_URandomNonblock() function: _PyOS_URandom()
-  works in non-blocking mode on Python 3.5
