 - Drop patch-CVE-2014-8964 (now included)
(upstream)
 - Update to 8.37
Version 8.37 28-April-2015
--------------------------
1.  When an (*ACCEPT) is triggered inside capturing parentheses, it arranges
    for those parentheses to be closed with whatever has been captured so far.
    However, it was failing to mark any other groups between the hightest
    capture so far and the currrent group as "unset". Thus, the ovector for
    those groups contained whatever was previously there. An example is the
    pattern /(x)|((*ACCEPT))/ when matched against "abcd".

2.  If an assertion condition was quantified with a minimum of zero (an odd
    thing to do, but it happened), SIGSEGV or other misbehaviour could occur.

3.  If a pattern in pcretest input had the P (POSIX) modifier followed by an
    unrecognized modifier, a crash could occur.

4.  An attempt to do global matching in pcretest with a zero-length ovector
    caused a crash.

5.  Fixed a memory leak during matching that could occur for a subpattern
    subroutine call (recursive or otherwise) if the number of captured groups
    that had to be saved was greater than ten.

6.  Catch a bad opcode during auto-possessification after compiling a bad UTF
    string with NO_UTF_CHECK. This is a tidyup, not a bug fix, as passing bad
    UTF with NO_UTF_CHECK is documented as having an undefined outcome.

7.  A UTF pattern containing a "not" match of a non-ASCII character and a
    subroutine reference could loop at compile time. Example: /[^\xff]((?1))/.

8. When a pattern is compiled, it remembers the highest back reference so that
   when matching, if the ovector is too small, extra memory can be obtained to
   use instead. A conditional subpattern whose condition is a check on a
   capture having happened, such as, for example in the pattern
   /^(?:(a)|b)(?(1)A|B)/, is another kind of back reference, but it was not
   setting the highest backreference number. This mattered only if pcre_exec()
   was called with an ovector that was too small to hold the capture, and there
   was no other kind of back reference (a situation which is probably quite
   rare). The effect of the bug was that the condition was always treated as
   FALSE when the capture could not be consulted, leading to a incorrect
   behaviour by pcre_exec(). This bug has been fixed.

9. A reference to a duplicated named group (either a back reference or a test
   for being set in a conditional) that occurred in a part of the pattern where
   PCRE_DUPNAMES was not set caused the amount of memory needed for the pattern
   to be incorrectly calculated, leading to overwriting.

10. A mutually recursive set of back references such as (\2)(\1) caused a
    segfault at study time (while trying to find the minimum matching length).
    The infinite loop is now broken (with the minimum length unset, that is,
    zero).

11. If an assertion that was used as a condition was quantified with a minimum
    of zero, matching went wrong. In particular, if the whole group had
    unlimited repetition and could match an empty string, a segfault was
    likely. The pattern (?(?=0)?)+ is an example that caused this. Perl allows
    assertions to be quantified, but not if they are being used as conditions,
    so the above pattern is faulted by Perl. PCRE has now been changed so that
    it also rejects such patterns.

12. A possessive capturing group such as (a)*+ with a minimum repeat of zero
    failed to allow the zero-repeat case if pcre2_exec() was called with an
    ovector too small to capture the group.

13. Fixed two bugs in pcretest that were discovered by fuzzing and reported by
    Red Hat Product Security:

    (a) A crash if /K and /F were both set with the option to save the compiled
    pattern.

    (b) Another crash if the option to print captured substrings in a callout
    was combined with setting a null ovector, for example \O\C+ as a subject
    string.

14. A pattern such as "((?2){0,1999}())?", which has a group containing a
    forward reference repeated a large (but limited) number of times within a
    repeated outer group that has a zero minimum quantifier, caused incorrect
    code to be compiled, leading to the error "internal error:
    previously-checked referenced subpattern not found" when an incorrect
    memory address was read. This bug was reported as "heap overflow",
    discovered by Kai Lu of Fortinet's FortiGuard Labs and given the CVE number
    CVE-2015-2325.

23. A pattern such as "((?+1)(\1))/" containing a forward reference \ 
subroutine
    call within a group that also contained a recursive back reference caused
    incorrect code to be compiled. This bug was reported as "heap \ 
overflow",
    discovered by Kai Lu of Fortinet's FortiGuard Labs, and given the CVE
    number CVE-2015-2326.

24. Computing the size of the JIT read-only data in advance has been a source
    of various issues, and new ones are still appear unfortunately. To fix
    existing and future issues, size computation is eliminated from the code,
    and replaced by on-demand memory allocation.

25. A pattern such as /(?i)[A-`]/, where characters in the other case are
    adjacent to the end of the range, and the range contained characters with
    more than one other case, caused incorrect behaviour when compiled in UTF
    mode. In that example, the range a-j was left out of the class.

26. Fix JIT compilation of conditional blocks, which assertion
    is converted to (*FAIL). E.g: /(?(?!))/.

27. The pattern /(?(?!)^)/ caused references to random memory. This bug was
    discovered by the LLVM fuzzer.

28. The assertion (?!) is optimized to (*FAIL). This was not handled correctly
    when this assertion was used as a condition, for example (?(?!)a|b). In
    pcre2_match() it worked by luck; in pcre2_dfa_match() it gave an incorrect
    error about an unsupported item.

29. For some types of pattern, for example /Z*(|d*){216}/, the auto-
    possessification code could take exponential time to complete. A recursion
    depth limit of 1000 has been imposed to limit the resources used by this
    optimization.

30. A pattern such as /(*UTF)[\S\V\H]/, which contains a negated special class
    such as \S in non-UCP mode, explicit wide characters (> 255) can be ignored
    because \S ensures they are all in the class. The code for doing this was
    interacting badly with the code for computing the amount of space needed to
    compile the pattern, leading to a buffer overflow. This bug was discovered
    by the LLVM fuzzer.

31. A pattern such as /((?2)+)((?1))/ which has mutual recursion nested inside
    other kinds of group caused stack overflow at compile time. This bug was
    discovered by the LLVM fuzzer.

32. A pattern such as /(?1)(?#?'){8}(a)/ which had a parenthesized comment
    between a subroutine call and its quantifier was incorrectly compiled,
    leading to buffer overflow or other errors. This bug was discovered by the
    LLVM fuzzer.

33. The illegal pattern /(?(?<E>.*!.*)?)/ was not being diagnosed as missing an
    assertion after (?(. The code was failing to check the character after
    (?(?< for the ! or = that would indicate a lookbehind assertion. This bug
    was discovered by the LLVM fuzzer.

34. A pattern such as /X((?2)()*+){2}+/ which has a possessive quantifier with
    a fixed maximum following a group that contains a subroutine reference was
    incorrectly compiled and could trigger buffer overflow. This bug was
    discovered by the LLVM fuzzer.

35. A mutual recursion within a lookbehind assertion such as (?<=((?2))((?1)))
    caused a stack overflow instead of the diagnosis of a non-fixed length
    lookbehind assertion. This bug was discovered by the LLVM fuzzer.

36. The use of \K in a positive lookbehind assertion in a non-anchored pattern
    (e.g. /(?<=\Ka)/) could make pcregrep loop.

37. There was a similar problem to 36 in pcretest for global matches.

38. If a greedy quantified \X was preceded by \C in UTF mode (e.g. \C\X*),
    and a subsequent item in the pattern caused a non-match, backtracking over
    the repeated \X did not stop, but carried on past the start of the subject,
    causing reference to random memory and/or a segfault. There were also some
    other cases where backtracking after \C could crash. This set of bugs was
    discovered by the LLVM fuzzer.

39. The function for finding the minimum length of a matching string could take
    a very long time if mutual recursion was present many times in a pattern,
    for example, /((?2){73}(?2))((?1))/. A better mutual recursion detection
    method has been implemented. This infelicity was discovered by the LLVM
    fuzzer.

40. Static linking against the PCRE library using the pkg-config module was
    failing on missing pthread symbols.

Log message:
Update to 8.36:

Version 8.36 26-September-2014
------------------------------

1.  Got rid of some compiler warnings in the C++ modules that were shown up by
    -Wmissing-field-initializers and -Wunused-parameter.

2.  The tests for quantifiers being too big (greater than 65535) were being
    applied after reading the number, and stupidly assuming that integer
    overflow would give a negative number. The tests are now applied as the
    numbers are read.

3.  Tidy code in pcre_exec.c where two branches that used to be different are
    now the same.

4.  The JIT compiler did not generate match limit checks for certain
    bracketed expressions with quantifiers. This may lead to exponential
    backtracking, instead of returning with PCRE_ERROR_MATCHLIMIT. This
    issue should be resolved now.

5.  Fixed an issue, which occures when nested alternatives are optimized
    with table jumps.

6.  Inserted two casts and changed some ints to size_t in the light of some
    reported 64-bit compiler warnings (Bugzilla 1477).

7.  Fixed a bug concerned with zero-minimum possessive groups that could match
    an empty string, which sometimes were behaving incorrectly in the
    interpreter (though correctly in the JIT matcher). This pcretest input is
    an example:

      '\A(?:[^"]++|"(?:[^"]*+|"")*+")++'
      NON QUOTED "QUOT""ED" AFTER "NOT MATCHED

    the interpreter was reporting a match of 'NON QUOTED ' only, whereas the
    JIT matcher and Perl both matched 'NON QUOTED "QUOT""ED" \ 
AFTER '. The test
    for an empty string was breaking the inner loop and carrying on at a lower
    level, when possessive repeated groups should always return to a higher
    level as they have no backtrack points in them. The empty string test now
    occurs at the outer level.

8.  Fixed a bug that was incorrectly auto-possessifying \w+ in the pattern
    ^\w+(?>\s*)(?<=\w) which caused it not to match "test test".

9.  Give a compile-time error for \o{} (as Perl does) and for \x{} (which Perl
    doesn't).

10. Change 8.34/15 introduced a bug that caused the amount of memory needed
    to hold a pattern to be incorrectly computed (too small) when there were
    named back references to duplicated names. This could cause "internal
    error: code overflow" or "double free or corruption" or other \ 
memory
    handling errors.

11. When named subpatterns had the same prefixes, back references could be
    confused. For example, in this pattern:

      /(?P<Name>a)?(?P<Name2>b)?(?(<Name>)c|d)*l/

    the reference to 'Name' was incorrectly treated as a reference to a
    duplicate name.

12. A pattern such as /^s?c/mi8 where the optional character has more than
    one "other case" was incorrectly compiled such that it would only \ 
try to
    match starting at "c".

13. When a pattern starting with \s was studied, VT was not included in the
    list of possible starting characters; this should have been part of the
    8.34/18 patch.

14. If a character class started [\Qx]... where x is any character, the class
    was incorrectly terminated at the ].

15. If a pattern that started with a caseless match for a character with more
    than one "other case" was studied, PCRE did not set up the \ 
starting code
    unit bit map for the list of possible characters. Now it does. This is an
    optimization improvement, not a bug fix.

16. The Unicode data tables have been updated to Unicode 7.0.0.

17. Fixed a number of memory leaks in pcregrep.

18. Avoid a compiler warning (from some compilers) for a function call with
    a cast that removes "const" from an lvalue by using an intermediate
    variable (to which the compiler does not object).

19. Incorrect code was compiled if a group that contained an internal recursive
    back reference was optional (had quantifier with a minimum of zero). This
    example compiled incorrect code: /(((a\2)|(a*)\g<-1>))*/ and other examples
    caused segmentation faults because of stack overflows at compile time.

20. A pattern such as /((?(R)a|(?1)))+/, which contains a recursion within a
    group that is quantified with an indefinite repeat, caused a compile-time
    loop which used up all the system stack and provoked a segmentation fault.
    This was not the same bug as 19 above.

21. Add PCRECPP_EXP_DECL declaration to operator<< in pcre_stringpiece.h.

Update to 8.35:

Release 8.35 04-April-2014
--------------------------

There have been performance improvements for classes containing non-ASCII
characters and the "auto-possessification" feature has been extended. Other
minor improvements have been implemented and bugs fixed. There is a new callout
feature to enable applications to do detailed stack checks at compile time, to
avoid running out of stack for deeply nested parentheses. The JIT compiler has
been extended with experimental support for ARM-64, MIPS-64, and PPC-LE.

Update to 8.34:

Release 8.34 15-December-2013
-----------------------------

As well as fixing the inevitable bugs, performance has been improved by
refactoring and extending the amount of "auto-possessification" that \ 
PCRE does.
Other notable changes:

.  Implemented PCRE_INFO_MATCH_EMPTY, which yields 1 if the pattern can match
   an empty string. If it can, pcretest shows this in its information output.

.  A back reference to a named subpattern when there is more than one of the
   same name now checks them in the order in which they appear in the pattern.
   The first one that is set is used for the reference. Previously only the
   first one was inspected. This change makes PCRE more compatible with Perl.

.  Unicode character properties were updated from Unicode 6.3.0.

.  The character VT has been added to the set of characters that match \s and
   are generally treated as white space, following this same change in Perl
   5.18. There is now no difference between "Perl space" and \ 
"POSIX space".

.  Perl has changed its handling of \8 and \9. If there is no previously
   encountered capturing group of those numbers, they are treated as the
   literal characters 8 and 9 instead of a binary zero followed by the
   literals. PCRE now does the same.

.  Following Perl, added \o{} to specify codepoints in octal, making it
   possible to specify values greater than 0777 and also making them
   unambiguous.

.  In UCP mode, \s was not matching two of the characters that Perl matches,
   namely NEL (U+0085) and MONGOLIAN VOWEL SEPARATOR (U+180E), though they
   were matched by \h.

.  Add JIT support for the 64 bit TileGX architecture.

.  Upgraded the handling of the POSIX classes [:graph:], [:print:], and
   [:punct:] when PCRE_UCP is set so as to include the same characters as Perl
   does in Unicode mode.

.  Perl no longer allows group names to start with digits, so I have made this
   change also in PCRE.

.  Added support for [[:<:]] and [[:>:]] as used in the BSD POSIX library to
   mean "start of word" and "end of word", respectively, as \ 
a transition aid.

Log message:
Release 8.32 30-November-2012
-----------------------------
This release fixes a number of bugs, but also has some new features. These are
the highlights:
.  There is now support for 32-bit character strings and UTF-32. Like the
   16-bit support, this is done by compiling a separate 32-bit library.

.  \X now matches a Unicode extended grapheme cluster.

.  Case-independent matching of Unicode characters that have more than one
   "other case" now makes all three (or more) characters equivalent. This
   applies, for example, to Greek Sigma, which has two lowercase versions.

.  Unicode character properties are updated to Unicode 6.2.0.

.  The EBCDIC support, which had decayed, has had a spring clean.

.  A number of JIT optimizations have been added, which give faster JIT
   execution speed. In addition, a new direct interface to JIT execution is
   available. This bypasses some of the sanity checks of pcre_exec() to give a
   noticeable speed-up.

.  A number of issues in pcregrep have been fixed, making it more compatible
   with GNU grep. In particular, --exclude and --include (and variants) apply
   to all files now, not just those obtained from scanning a directory
   recursively. In Windows environments, the default action for directories is
   now "skip" instead of "read" (which provokes an error).

.  If the --only-matching (-o) option in pcregrep is specified multiple
   times, each one causes appropriate output. For example, -o1 -o2 outputs the
   substrings matched by the 1st and 2nd capturing parentheses. A separating
   string can be specified by --om-separator (default empty).

.  When PCRE is built via Autotools using a version of gcc that has the
   "visibility" feature, it is used to hide internal library functions \ 
that are
   not part of the public API.
