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.
