The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2832 advisory.
OpenSC before 0.20.0-rc1 has an out-of-bounds access of an ASN.1 Bitstring in decode_bit_string in libopensc/asn1.c. (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)
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)
The gemsafe GPK smart card software driver in OpenSC before 0.21.0-rc1 has a stack-based buffer overflow in sc_pkcs15emu_gemsafeGPK_init. (CVE-2020-26571)
The TCOS smart card software driver in OpenSC before 0.21.0-rc1 has a stack-based buffer overflow in tcos_decipher. (CVE-2020-26572)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
