Crypt::OpenSSL::PKCS12 vulnerabilities

Crypt::OpenSSL::PKCS12 versions before 1.96 for Perl allow a heap OOB read in print_attribute for UTF8STRING attributes. The print_attribute() function copies an ASN.1 attribute value into a memory buffer without adding a NUL terminator, leading to unsafe reads of adjacent bytes.

Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl truncates passwords with embedded NULLs. Password parameters in PKCS12.xs are declared char *, which leads to the loss of password length in Perl.

Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl have out-of-bounds (OOB) write flaws. When parsing a PKCS12 file with a >= 1 GiB OCTET STRING (or BIT STRING) attribute, a heap out-of-bounds write could be triggered, leading to remote-code-execution potential (RCE) due to a signed integer overflow in the size calculation passed to Renew().

In the Crypt::OpenSSL::PKCS12 library for Perl before version 1.98, there is a NULL pointer dereference vulnerability in the print_attribute function when handling a zero-length BMPSTRING attribute. The zero length causes the buffer to be freed and return NULL, and a subsequent strlen call on that pointer crashes the process.
