       perl5244delta - what is new for perl v5.24.4

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

       If you are upgrading from an earlier release such as 5.24.2, first read
       perl5243delta, which describes differences between 5.24.2 and 5.24.3.

   [CVE-2018-6797] heap-buffer-overflow (WRITE of size 1) in S_regatom
       A crafted regular expression could cause a heap buffer write overflow,
       with control over the bytes written.  [perl #132227]

   [CVE-2018-6798] Heap-buffer-overflow in Perl__byte_dump_string (utf8.c)
       Matching a crafted locale dependent regular expression could cause a
       heap buffer read overflow and potentially information disclosure.
       [perl #132063] <https://rt.perl.org/Public/Bug/Display.html?id=132063>

   [CVE-2018-6913] heap-buffer-overflow in S_pack_rec
       "pack()" could cause a heap buffer write overflow with a large item
       count.  [perl #131844]

   Assertion failure in Perl__core_swash_init (utf8.c)
       Control characters in a supposed Unicode property name could cause perl
       to crash.  This has been fixed.  [perl #132055]
       <https://rt.perl.org/Public/Bug/Display.html?id=132055> [perl #132553]
       <https://rt.perl.org/Public/Bug/Display.html?id=132553> [perl #132658]

Incompatible Changes
       There are no changes intentionally incompatible with 5.24.3.  If any
       exist, they are bugs, and we request that you submit a report.  See
       "Reporting Bugs" below.

Modules and Pragmata
   Updated Modules and Pragmata
       o   Module::CoreList has been upgraded from version 5.20170922_24 to

Selected Bug Fixes
       o   The "readpipe()" built-in function now checks at compile time that
           it has only one parameter expression, and puts it in scalar
           context, thus ensuring that it doesn't corrupt the stack at
           runtime.  [perl #4574]

       Perl 5.24.4 represents approximately 7 months of development since Perl
       5.24.3 and contains approximately 2,400 lines of changes across 49
       files from 12 authors.

       Excluding auto-generated files, documentation and release tools, there
       were approximately 1,300 lines of changes to 12 .pm, .t, .c and .h

       Perl continues to flourish into its third decade thanks to a vibrant
       community of users and developers.  The following people are known to
       have contributed the improvements that became Perl 5.24.4:

       Abigail, Chris 'BinGOs' Williams, John SJ Anderson, Karen Etheridge,
       Karl Williamson, Renee Baecker, Sawyer X, Steve Hay, Todd Rinaldo, Tony
       Cook, Yves Orton, Zefram.

       The list above is almost certainly incomplete as it is automatically
       generated from version control history.  In particular, it does not
       include the names of the (very much appreciated) contributors who
       reported issues to the Perl bug tracker.

       Many of the changes included in this version originated in the CPAN
       modules included in Perl's core.  We're grateful to the entire CPAN
       community for helping Perl to flourish.

       For a more complete list of all of Perl's historical contributors,
       please see the AUTHORS file in the Perl source distribution.

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 <https://rt.perl.org/> .  There may also be information at
       <http://www.perl.org/> , the Perl Home Page.

       If you believe you have an unreported bug, please run the 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 "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
       how to report the issue.
