PSIRT then +reported it to the Perl security team. +.PP +Perl for Windows relies on the system path environment variable to +find the shell (\f(CW\*(C`cmd.exe\*(C'\fR). When running an executable which uses +Windows Perl interpreter, Perl attempts to find and execute \f(CW\*(C`cmd.exe\*(C'\fR +within the operating system. However, due to path search order issues, +Perl initially looks for cmd.exe in the current working directory. +.PP +An attacker with limited privileges can exploit this behavior by +placing \f(CW\*(C`cmd.exe\*(C'\fR in locations with weak permissions, such as +\&\f(CW\*(C`C:\eProgramData\*(C'\fR. By doing so, when an administrator attempts to use +this executable from these compromised locations, arbitrary code can +be executed. +.SH Acknowledgements +.IX Header "Acknowledgements" +Perl 5.36.3 represents approximately 1 month of development since Perl +5.36.1 and contains approximately 2,300 lines of changes across 38 files +from 4 authors. +.PP +Excluding auto-generated files, documentation and release tools, there were +approximately 1,400 lines of changes to 8 .pm, .t, .c and .h files. +.PP +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 5.36.3: +.PP +Karl Williamson, Paul Evans, Steve Hay, Tony Cook. +.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 perl bug database +at <https://github.com/Perl/perl5/issues>. There may also be information at +<http://www.perl.org/>, the Perl Home Page. +.PP +If you believe you have an unreported bug, please open an issue at +<https://github.com/Perl/perl5/issues>. Be sure to trim your bug down to a +tiny but sufficient test case. +.PP +If the bug you are reporting has security implications which make it +inappropriate to send to a public issue tracker, then see +"SECURITY VULNERABILITY CONTACT INFORMATION" in perlsec +for details of how to report the issue. +.SH "Give Thanks" +.IX Header "Give Thanks" +If you wish to thank the Perl 5 Porters for the work we had done in Perl 5, +you can do so by running the \f(CW\*(C`perlthanks\*(C'\fR program: +.PP +.Vb 1 +\& perlthanks +.Ve +.PP +This will send an email to the Perl 5 Porters list with your show of thanks. +.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. |
