C_WrapKey doesn't check
CKA_EXTRACTABLEon the key being wrapped. NeitherWP11_Generic_SerializeKeynorWP11_Rsa_SerializeKeyPTPKCS8check the extractable flag before serializing key material. Per the PKCS#11 specification,C_Wrapkeyhas to returnCKR_KEY_UNEXTRACTABLEwhen attempting to wrap a key withCKA_EXTRACTABLE=CK_FALSE. This allows an attacker with a valid session to export any key material through wrapping, even keys explicitly marked as non-extractable, defeating the fundamental key protection model.Fix the issue and add regression test.
Fix the unit test which expected to be wrapping the key, but it didn't set
CKA_ETRACTABLEtoCK_TRUE
