 perl5242delta - what is new for perl v5.24.2

DDEESSCCRRIIPPTTIIOONN #

 This document describes differences between the 5.24.1 release and the
 5.24.2 release.

 If you are upgrading from an earlier release such as 5.24.0, first read
 perl5241delta, which describes differences between 5.24.0 and 5.24.1.

SSeeccuurriittyy IImmpprroovveedd hhaannddlliinngg ooff ‘’..‘’ iinn @@IINNCC iinn bbaassee..ppmm The handling of (the removal of) ‘.’ in @INC in base has been improved. This resolves some problematic behaviour in the approach taken in Perl 5.24.1, which is probably best described in the following two threads on the Perl 5 Porters mailing list: http://www.nntp.perl.org/group/perl.perl5.porters/2016/08/msg238991.html, http://www.nntp.perl.org/group/perl.perl5.porters/2016/10/msg240297.html.

“"EEssccaappeedd"” ccoolloonnss aanndd rreellaattiivvee ppaatthhss iinn PPAATTHH On Unix systems, Perl treats any relative paths in the PATH environment variable as tainted when starting a new process. Previously, it was allowing a backslash to escape a colon (unlike the OS), consequently allowing relative paths to be considered safe if the PATH was set to something like “/:.”. The check has been fixed to treat “.” as tainted in that example.

AAcckknnoowwlleeddggeemmeennttss Perl 5.24.2 represents approximately 6 months of development since Perl 5.24.1 and contains approximately 2,500 lines of changes across 53 files from 18 authors.

 Excluding auto-generated files, documentation and release tools, there
 were approximately 960 lines of changes to 17 .pm, .t, .c and .h files.

 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 5.24.2:

 Aaron Crane, Abigail, Aristotle Pagaltzis, Chris 'BinGOs' Williams, Dan
 Collins, David Mitchell, Eric Herman, Father Chrysostomos, James E
 Keenan, Karl Williamson, Lukas Mai, Renee Baecker, Ricardo Signes, Sawyer
 X, Stevan Little, Steve Hay, Tony Cook, Yves Orton.

 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 _A_U_T_H_O_R_S file in the Perl source distribution.

RReeppoorrttiinngg BBuuggss 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
 "SECURITY VULNERABILITY CONTACT INFORMATION" in perlsec for details of
 how to report the issue.
