Source   Latest Release: perl-5.26.0-RC2

NAME ^

perl5255delta - what is new for perl v5.25.5

DESCRIPTION ^

This document describes differences between the 5.25.4 release and the 5.25.5 release.

If you are upgrading from an earlier release such as 5.25.3, first read perl5254delta, which describes differences between 5.25.3 and 5.25.4.

Security ^

"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 /\:.. The check has been fixed to treat . as tainted in that example.

Platform-Specific Notes

VMS
  • The path separator for the PERL5LIB and PERLLIB environment entries is now a colon (:) when running under a Unix shell. There is no change when running under DCL (it's still |).
  • Remove some VMS-specific hacks from showlex.t. These were added 15 years ago, and are no longer necessary for any VMS version now supported.
Win32
  • Tweaks for Win32 VC vs GCC detection makefile code. This fixes issue that CCHOME depends on CCTYPE, which in auto detect mode is set after CCHOME, so CCHOME uses the uninit CCTYPE var. Also fix else vs .ELSE in makefile.mk

Obituary ^

Jon Portnoy (AVENJ), a prolific Perl author and admired Gentoo community member, has passed away on August 10, 2016. He will be remembered and missed by all those with which he came in contact and enriched with his intellect, wit, and spirit.

Reporting Bugs ^

If you find what you think is a bug, you might check 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.
