            Bug ID: 241010
           Summary: key_dup_keymsg bcopy too much bytes
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org

fix using src->sadb_key_bits

In the function key_dup_keymsg() of netipsec/key.c, the parameter len is the
length of the SADB extension (either SADB_EXT_KEY_AUTH or SADB_EXT_KEY_ENCR=
YPT)
not the length of the key. The real length used by the second malloc and the
bcopy should be either (len - sizeof(struct sadb_key)) or (src->sadb_key_bi=
ts
>> 3).
