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: , . .SS """Escaped"" colons and relative paths in PATH" .IX Subsection """Escaped"" colons and relative paths in PATH" 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 \f(CW\*(C`/\e:.\*(C'\fR. The check has been fixed to treat \f(CW\*(C`.\*(C'\fR as tainted in that example. .SH "Modules and Pragmata" .IX Header "Modules and Pragmata" .SS "Updated Modules and Pragmata" .IX Subsection "Updated Modules and Pragmata" .IP \(bu 4 base has been upgraded from version 2.23 to 2.23_01. .IP \(bu 4 Module::CoreList has been upgraded from version 5.20170114_24 to 5.20170715_24. .SH "Selected Bug Fixes" .IX Header "Selected Bug Fixes" .IP \(bu 4 Fixed a crash with \f(CW\*(C`s///l\*(C'\fR where it thought it was dealing with UTF\-8 when it wasn't. [GH #15543] .SH Acknowledgements .IX Header "Acknowledgements" 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. .PP Excluding auto-generated files, documentation and release tools, there were approximately 960 lines of changes to 17 .pm, .t, .c and .h files. .PP 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: .PP 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. .PP 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. .PP 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. .PP For a more complete list of all of Perl's historical contributors, please see the \fIAUTHORS\fR file in the Perl source distribution. .SH "Reporting Bugs" .IX Header "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 . There may also be information at , the Perl Home Page. .PP 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 \f(CW\*(C`perl \-V\*(C'\fR, will be sent off to perlbug@perl.org to be analysed by the Perl porting team. .PP 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. .SH "SEE ALSO" .IX Header "SEE ALSO" The \fIChanges\fR file for an explanation of how to view exhaustive details on what changed. .PP The \fIINSTALL\fR file for how to build Perl. .PP The \fIREADME\fR file for general stuff. .PP The \fIArtistic\fR and \fICopying\fR files for copyright information.
