Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl have out of bound (OOB) write flaws
Description

Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl have out of bound (OOB) write flaws. When parsing a PKCS12 file, with a >= 1 GiB OCTET STRING (or BIT STRING) attribute on a SAFEBAG, via info() or info_as_hash(), a heap-OOB-WRITE would be triggered which could have Remote Code Execution (RCE) potential.
