    "description": "Crypt::OpenSSL::PKCS12 versions before 1.96 for Perl permits a heap OOB read in print_attribute UTF8STRING path.\n\nprint_attribute() copies a UTF8STRING ASN.1 attribute value into a heap buffer sized exactly to its declared length via strncpy, leaving no NUL terminator. Downstream callers run strlen() on the result and pass the inflated length to newSVpvn(), copying attacker-influenced adjacent heap bytes into a Perl scalar.",
