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. A flaw was found in Perl due to improper handling of the property name by the S_parse_uniprop_string function in regcomp.c. This issue could allow an attacker to to bypass security restrictions and use a specially crafted regular expression input to write to unallocated space.
