=head1 NAME

perl5243delta - what is new for perl v5.24.3

=head1 DESCRIPTION

This document describes differences between the 5.24.2 release and the 5.24.3
release.

If you are upgrading from an earlier release such as 5.24.1, first read
L<perl5242delta>, which describes differences between 5.24.1 and 5.24.2.

=head1 Security

=head2 [CVE-2017-12837] Heap buffer overflow in regular expression compiler

Compiling certain regular expression patterns with the case-insensitive
modifier could cause a heap buffer overflow and crash perl.  This has now been
fixed.
L<[perl #131582]|https://rt.perl.org/Public/Bug/Display.html?id=131582>

=head2 [CVE-2017-12883] Buffer over-read in regular expression parser

For certain types of syntax error in a regular expression pattern, the error
message could either contain the contents of a random, possibly large, chunk of
memory, or could crash perl.  This has now been fixed.
L<[perl #131598]|https://rt.perl.org/Public/Bug/Display.html?id=131598>

=head2 [CVE-2017-12814] C<$ENV{$key}> stack buffer overflow on Windows

A possible stack buffer overflow in the C<%ENV> code on Windows has been fixed
by removing the buffer completely since it was superfluous anyway.
L<[perl #131665]|https://rt.perl.org/Public/Bug/Display.html?id=131665>

=head1 Incompatible Changes

There are no changes intentionally incompatible with 5.24.2.  If any exist,
they are bugs, and we request that you submit a report.  See L</Reporting
Bugs> below.

=head1 Configuration and Compilation

=over 4

=item *

When building with GCC 6 and link-time optimization (the B<-flto> option to
B<gcc>), F<Configure> was treating all probed symbols as present on the system,
regardless of whether they actually exist.  This has been fixed.
L<[perl #128131]|https://rt.perl.org/Public/Bug/Display.html?id=128131>

=item *

F<Configure> now aborts if both C<-Duselongdouble> and C<-Dusequadmath> are
requested.
L<[perl #126203]|https://rt.perl.org/Public/Bug/Display.html?id=126203>

=item *

Fixed a bug in which F<Configure> could append C<-quadmath> to the archname
even if it was already present.
L<[perl #128538]|https://rt.perl.org/Public/Bug/Display.html?id=128538>

=item *

Clang builds with C<-DPERL_GLOBAL_STRUCT> or C<-DPERL_GLOBAL_STRUCT_PRIVATE>
have been fixed (by disabling Thread Safety Analysis for these configurations).

Building XS modules with GCC 6 in a 64-bit build of Perl failed due to
incorrect mapping of C<strtoll> and C<strtoull>.  This has now been fixed.

=head1 Selected Bug Fixes

=over 4

=item *

C<< /@0{0*-E<gt>@*/*0 >> and similar contortions used to crash, but no longer
do, but merely produce a syntax error.
L<[perl #128171]|https://rt.perl.org/Public/Bug/Display.html?id=128171>

=item *

C<do> or C<require> with an argument which is a reference or typeglob which,
when stringified, contains a null character, started crashing in Perl 5.20, but
has now been fixed.
L<[perl #128182]|https://rt.perl.org/Public/Bug/Display.html?id=128182>

=item *

Expressions containing an C<&&> or C<||> operator (or their synonyms C<and> and
C<or>) were being compiled incorrectly in some cases.  If the left-hand side
consisted of either a negated bareword constant or a negated C<do {}> block
containing a constant expression, and the right-hand side consisted of a
negated non-foldable expression, one of the negations was effectively ignored.
The same was true of C<if> and C<unless> statement modifiers, though with the
left-hand and right-hand sides swapped.  This long-standing bug has now been
fixed.
L<[perl #127952]|https://rt.perl.org/Public/Bug/Display.html?id=127952>

=item *

C<reset> with an argument no longer crashes when encountering stash entries
other than globs.
L<[perl #128106]|https://rt.perl.org/Public/Bug/Display.html?id=128106>

=item *

Assignment of hashes to, and deletion of, typeglobs named C<*::::::> no longer
causes crashes.
L<[perl #128086]|https://rt.perl.org/Public/Bug/Display.html?id=128086>

=item *

Assignment variants of any bitwise ops under the C<bitwise> feature would crash
if the left-hand side was an array or hash.
L<[perl #128204]|https://rt.perl.org/Public/Bug/Display.html?id=128204>

=item *

C<socket> now leaves the error code returned by the system in C<$!> on failure.
L<[perl #128316]|https://rt.perl.org/Public/Bug/Display.html?id=128316>

=item *

Parsing bad POSIX charclasses no longer leaks memory.
L<[perl #128313]|https://rt.perl.org/Public/Bug/Display.html?id=128313>

=item *

Since Perl 5.20, line numbers have been off by one when perl is invoked with
the B<-x> switch.  This has been fixed.
L<[perl #128508]|https://rt.perl.org/Public/Bug/Display.html?id=128508>

=item *

Some obscure cases of subroutines and file handles being freed at the same time
could result in crashes, but have been fixed.  The crash was introduced in Perl
5.22.
L<[perl #128597]|https://rt.perl.org/Public/Bug/Display.html?id=128597>

=item *

Some regular expression parsing glitches could lead to assertion failures with
regular expressions such as C</(?E<lt>=/> and C</(?E<lt>!/>.  This has now been
fixed.
L<[perl #128170]|https://rt.perl.org/Public/Bug/Display.html?id=128170>

=item *

C<gethostent> and similar functions now perform a null check internally, to
avoid crashing with the torsocks library.  This was a regression from Perl
5.22.
L<[perl #128740]|https://rt.perl.org/Public/Bug/Display.html?id=128740>

=item *

Mentioning the same constant twice in a row (which is a syntax error) no longer
fails an assertion under debugging builds.  This was a regression from Perl
5.20.
L<[perl #126482]|https://rt.perl.org/Public/Bug/Display.html?id=126482>

=item *

In Perl 5.24 C<fchown> was changed not to accept negative one as an argument
because in some platforms that is an error.  However, in some other platforms
that is an acceptable argument.  This change has been reverted.
L<[perl #128967]|https://rt.perl.org/Public/Bug/Display.html?id=128967>.

=item *

C<@{x> followed by a newline where C<"x"> represents a control or non-ASCII
character no longer produces a garbled syntax error message or a crash.
L<[perl #128951]|https://rt.perl.org/Public/Bug/Display.html?id=128951>

=item *

A regression in Perl 5.24 with C<tr/\N{U+...}/foo/> when the code point was
between 128 and 255 has been fixed.
L<[perl #128734]|https://rt.perl.org/Public/Bug/Display.html?id=128734>.

=item *

Many issues relating to C<printf "%a"> of hexadecimal floating point were
fixed.  In addition, the "subnormals" (formerly known as "denormals") floating
point numbers are now supported both with the plain IEEE 754 floating point
numbers (64-bit or 128-bit) and the x86 80-bit "extended precision".  Note that
subnormal hexadecimal floating point literals will give a warning about
"exponent underflow".

L<[perl #128919]|https://rt.perl.org/Public/Bug/Display.html?id=128919>

=item *

The parser could sometimes crash if a bareword came after C<evalbytes>.
L<[perl #129196]|https://rt.perl.org/Public/Bug/Display.html?id=129196>

=item *

Fixed a place where the regex parser was not setting the syntax error correctly
on a syntactically incorrect pattern.
L<[perl #129122]|https://rt.perl.org/Public/Bug/Display.html?id=129122>

=item *

A vulnerability in Perl's C<sprintf> implementation has been fixed by avoiding
a possible memory wrap.

=head1 Reporting Bugs

If you find what you think is a bug, you might check the articles recently
posted to the comp.lang.perl.misc newsgroup and the perl bug database at
L<https://rt.perl.org/> .  There may also be information at
L<http://www.perl.org/> , the Perl Home Page.

If you believe you have an unreported bug, please run the L<perlbug> program
included with your release.  Be sure to trim your bug down to a tiny but
sufficient test case.  Your bug report, along with the output of C<perl -V>,
will be sent off to perlbug@perl.org to be analysed by the Perl porting team.

If the bug you are reporting has security implications which make it
inappropriate to send to a publicly archived mailing list, then see
L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION> for details of how to
report the issue.
