OpenSC before 0.20.0 has a double free in coolkey_free_private_data because coolkey_add_object in libopensc/card-coolkey.c lacks a uniqueness check.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - opensc: Double free in coolkey_free_private_data in libopensc/card-coolkey.c (CVE-2019-20792)
