commit 66a18ffa057565b6bf292e50969ea27ce33b394c
Author: Than Ngo <than@redhat.com>

Fix resource leak
1. Defect type: RESOURCE_LEAK
4. opencryptoki-3.24.0/usr/sbin/pkcscca/pkcscca.c:740:5: alloc_fn: Storage is returned from allocation function "malloc".
5. opencryptoki-3.24.0/usr/sbin/pkcscca/pkcscca.c:740:5: var_assign: Assigning: "new_key->opaque_attr" = storage returned from "malloc(attrs[0].ulValueLen)".
7. opencryptoki-3.24.0/usr/sbin/pkcscca/pkcscca.c:748:5: noescape: Resource "new_key->opaque_attr" is not freed or pointed-to in "memcpy". [Note: The source code implementation of the function has been overridden by a builtin model.]
9. opencryptoki-3.24.0/usr/sbin/pkcscca/pkcscca.c:752:9: leaked_storage: Freeing "new_key" without freeing its pointer field "opaque_attr" leaks the storage that "opaque_attr" points to.
750| if (!new_key->label) {
751| print_error("Malloc of %lu bytes failed!", attrs[2].ulValueLen + 1);
752|-> free(new_key);
753| return 2;
754| }
2. Defect type: RESOURCE_LEAK
15. opencryptoki-3.24.0/usr/lib/common/mech_ec.c:1140:5: alloc_arg: "object_mgr_create_skel" allocates memory that is stored into "temp_obj".
21. opencryptoki-3.24.0/usr/lib/common/mech_ec.c:1182:5: leaked_storage: Variable "temp_obj" going out of scope leaks the storage it points to.
1180| free(derived_key);

1182|-> return rc;
1183| }
