openssl: Fix CVE-2024-0727

Browse Source 
PKCS12 structures contain PKCS7 ContentInfo fields. These fields are
optional and can be NULL even if the "type" is a valid value. OpenSSL
was not properly accounting for this and a NULL dereference can occur
causing a crash.

Subject: [PATCH] Add NULL checks where ContentInfo data can be NULL
PKCS12 structures contain PKCS7 ContentInfo fields. These fields are
optional and can be NULL even if the "type" is a valid value. OpenSSL
was not properly accounting for this and a NULL dereference can occur
causing a crash.
