+
+perl54111delta - what is new for perl v5.41.11
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.41.10 release and the 5.41.11
+release.
+
+If you are upgrading from an earlier release such as 5.41.9, first read
+L<perl54110delta>, which describes differences between 5.41.9 and 5.41.10.

+

+
+Perl now supports Unicode 16.0
+L<https://www.unicode.org/versions/Unicode16.0.0/> including the changes
+introduced in 15.1 L<https://www.unicode.org/versions/Unicode15.1.0/>.
+
+=head1 Security
+
+=head2 [CVE-2024-56406] Heap buffer overflow vulnerability with tr//
+
+A heap buffer overflow vulnerability was discovered in Perl.
+
+When there are non-ASCII bytes in the left-hand-side of the C<tr> operator,
+C<S_do_trans_invmap()> can overflow the destination pointer C<d>.
+
+  $ perl -e '$_ = "\x{FF}" x 1000000; tr/\xFF/\x{100}/;'
+  Segmentation fault (core dumped)
+
+It is believed that this vulnerability can enable Denial of Service or
+Arbitrary Code Execution attacks on platforms that lack sufficient defenses.
+
+Discovered by: Nathan Mills.

+=head1 Acknowledgements
+
+Perl 5.41.11 represents approximately 4 weeks of development since Perl
+5.41.10 and contains approximately 250,000 lines of changes across 460 files
+from 22 authors.
+
+Excluding auto-generated files, documentation and release tools, there were
+approximately 39,000 lines of changes to 320 .pm, .t, .c and .h files.
+
+Perl continues to flourish into its fourth decade thanks to a vibrant
+community of users and developers. The following people are known to have
+contributed the improvements that became Perl 5.41.11:
+
+Chad Granum, Chris 'BinGOs' Williams, Dan Book, Daniel Dragan, Graham Knop,
+James E Keenan, Karen Etheridge, Karl Williamson, Leon Timmermans, Lukas
+Mai, Marek Rouchal, Paul Evans, Peter Eisentraut, Peter John Acklam,
+Philippe Bruhat (BooK), Richard Leach, Steve Hay, TAKAI Kousuke, Thibault
+Duponchelle, Tony Cook, Unicode Consortium, Vladimír Marek.
+
+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 F<AUTHORS> file in the Perl source distribution.

+at L<https://github.com/Perl/perl5/issues>. There may also be information at
+L<https://www.perl.org/>, the Perl Home Page.
+
+If you believe you have an unreported bug, please open an issue at
+L<https://github.com/Perl/perl5/issues>. Be sure to trim your bug down to a
+tiny but sufficient test case.

+inappropriate to send to a public issue tracker, then see
+L<perlsec/SECURITY VULNERABILITY CONTACT INFORMATION>
+for details of how to report the issue.
