[GH #16185] \n\n[CVE-2018-6798] Heap-buffer-overflow in Perlbytedumpstring (utf8.c)\nMatching a crafted locale dependent regular expression could cause a heap buffer read\noverflow and potentially information disclosure. [GH #16143]\n\n\n[CVE-2018-6913] heap-buffer-overflow in Spackrec\n\"pack()\" could cause a heap buffer write overflow with a large item count. [GH #16098]\n\n\nAssertion failure in Perlcoreswashinit (utf8.c)\nControl characters in a supposed Unicode property name could cause perl to crash. This has\nbeen fixed. [perl #132055] [perl\n#132553] [perl #132658]\n\n\n#### Incompatible Changes\n\nThere are no changes intentionally incompatible with 5.24.3. If any exist, they are bugs,\nand we request that you submit a report. See \"Reporting Bugs\" below.\n\n#### Modules and Pragmata\n\n#### Updated Modules and Pragmata\n\n• Module::CoreList has been upgraded from version 5.2017092224 to 5.2018041424.\n\n#### Selected Bug Fixes\n\n• The \"readpipe()\" built-in function now checks at compile time that it has only one\nparameter expression, and puts it in scalar context, thus ensuring that it doesn't\ncorrupt the stack at runtime. [GH #2793] \n\n### Acknowledgements\n\nPerl 5.24.4 represents approximately 7 months of development since Perl 5.24.3 and contains\napproximately 2,400 lines of changes across 49 files from 12 authors.\n\nExcluding auto-generated files, documentation and release tools, there were approximately\n1,300 lines of changes to 12 .pm, .t, .c and .h files.\n\nPerl continues to flourish into its third decade thanks to a vibrant community of users and\ndevelopers. The following people are known to have contributed the improvements that became\nPerl 5.24.4:\n\nAbigail, Chris 'BinGOs' Williams, John SJ Anderson, Karen Etheridge, Karl Williamson, Renee\nBaecker, Sawyer X, Steve Hay, Todd Rinaldo, Tony Cook, Yves Orton, Zefram.\n\nThe list above is almost certainly incomplete as it is automatically generated from version\ncontrol history. In particular, it does not include the names of the (very much appreciated)\ncontributors who reported issues to the Perl bug tracker.\n\nMany of the changes included in this version originated in the CPAN modules included in\nPerl's core. We're grateful to the entire CPAN community for helping Perl to flourish.\n\nFor a more complete list of all of Perl's historical contributors, please see the AUTHORS\nfile in the Perl source distribution.\n\n#### Reporting Bugs\n\nIf you find what you think is a bug, you might check the articles recently posted to the\ncomp.lang.perl.misc newsgroup and the perl bug database at . There\nmay also be information at , the Perl Home Page.\n\nIf you believe you have an unreported bug, please run the perlbug program included with your\nrelease. Be sure to trim your bug down to a tiny but sufficient test case. Your bug report,\nalong with the output of \"perl -V\", will be sent off to perlbug@perl.org to be analysed by\nthe Perl porting team.\n\nIf the bug you are reporting has security implications which make it inappropriate to send to\na publicly archived mailing list, then see \"SECURITY VULNERABILITY CONTACT INFORMATION\" in\nperlsec for details of how to report the issue.\n\n### SEE ALSO\n\nThe Changes file for an explanation of how to view exhaustive details on what changed.\n\nThe INSTALL file for how to build Perl.\n\nThe README file for general stuff.\n\nThe Artistic and Copying files for copyright information.\n\n\n\nperl v5.34.0 2025-07-25 PERL5244DELTA(1)\n\n" } ], "structuredContent": { "command": "PERL5244DELTA", "section": "1", "mode": "man", "summary": "perl5244delta - what is new for perl v5.24.4", "synopsis": null, "tldr_summary": null, "tldr_examples": [], "tldr_source": null, "flags": [], "examples": [], "see_also": [], "section_outline": [ { "name": "NAME", "lines": 2, "subsections": [] }, { "name": "DESCRIPTION", "lines": 5, "subsections": [] }, { "name": "Security", "lines": 19, "subsections": [ { "name": "Incompatible Changes", "lines": 3 }, { "name": "Modules and Pragmata", "lines": 1 }, { "name": "Updated Modules and Pragmata", "lines": 2 }, { "name": "Selected Bug Fixes", "lines": 4 } ] }, { "name": "Acknowledgements", "lines": 23, "subsections": [ { "name": "Reporting Bugs", "lines": 13 } ] }, { "name": "SEE ALSO", "lines": 11, "subsections": [] } ], "sections": { "NAME": { "content": "perl5244delta - what is new for perl v5.24.4\n", "subsections": [] }, "DESCRIPTION": { "content": "This document describes differences between the 5.24.3 release and the 5.24.4 release.\n\nIf you are upgrading from an earlier release such as 5.24.2, first read perl5243delta, which\ndescribes differences between 5.24.2 and 5.24.3.\n", "subsections": [] }, "Security": { "content": "[CVE-2018-6797] heap-buffer-overflow (WRITE of size 1) in Sregatom (regcomp.c)\nA crafted regular expression could cause a heap buffer write overflow, with control over the\nbytes written.
