The remote Amazon Linux 2 host is missing a security update.Description
The version of opensc installed on the remote host is prior to 0.19.0-5.

(CVE-2019-15945)
- OpenSC before 0.20.0-rc1 has an out-of-bounds access of an ASN.1 Octet string in asn1_decode_entry in libopensc/asn1.c. (CVE-2019-15946)
- An issue was discovered in OpenSC through 0.19.0 and 0.20.x through 0.20.0-rc3. libopensc/card-setcos.c has an incorrect read operation during parsing of a SETCOS file attribute. (CVE-2019-19479)
- 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. (CVE-2019-20792)
- The Oberthur smart card software driver in OpenSC before 0.21.0-rc1 has a heap-based buffer overflow in sc_oberthur_read_file. (CVE-2020-26570)
