In Perl before 5.38.2, S_parse_uniprop_string in regcomp.c can write to unallocated space because a property name associated with a \p{...} regular expression construct is mishandled. The earliest affected version is 5.30.0. https://github.com/Perl/perl5/commit/12c313ce49b36160a7ca2e9b07ad5bd92ee4a010 https://github.com/Perl/perl5/commit/7047915eef37fccd93e7cd985c29fe6be54650b6 https://github.com/Perl/perl5/commit/ff1f9f59360afeebd6f75ca1502f5c3ebf077da3
