The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - calipso: fix memory leak in netlbl_calipso_add_pass() If IPv6 support is disabled at boot     (ipv6.disable=1), the calipso_init() -> netlbl_calipso_ops_register() function isn't called, and the     netlbl_calipso_ops_get() function always returns NULL. In this case, the netlbl_calipso_add_pass()     function allocates memory for the doi_def variable but doesn't free it with the calipso_doi_free(). BUG:
