The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2019-2154 advisory.
Several buffer overflows when handling responses from a Muscle Card in muscle_list_files in libopensc/card-muscle.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.
(CVE-2018-16391)
Several buffer overflows when handling responses from a TCOS Card in tcos_select_file in libopensc/card- tcos.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact. (CVE-2018-16392)
A buffer overflow when handling string concatenation in util_acl_to_str in tools/util.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact. (CVE-2018-16418)
Several buffer overflows when handling responses from a Cryptoflex card in read_public_key in tools/cryptoflex-tool.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.
(CVE-2018-16419)
Several buffer overflows when handling responses from an ePass 2003 Card in decrypt_response in libopensc/card-epass2003.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.
(CVE-2018-16420)
Several buffer overflows when handling responses from a CAC Card in cac_get_serial_nr_from_CUID in libopensc/card-cac.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.
(CVE-2018-16421)
A single byte buffer overflow when handling responses from an esteid Card in sc_pkcs15emu_esteid_init in libopensc/pkcs15-esteid.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.
(CVE-2018-16422)
A double free when handling responses from a smartcard in sc_file_set_sec_attr in libopensc/sc.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact. (CVE-2018-16423)
Endless recursion when handling responses from an IAS-ECC card in iasecc_select_file in libopensc/card- iasecc.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to hang or crash the opensc library using programs. (CVE-2018-16426)
Various out of bounds reads when handling responses in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to potentially crash the opensc library using programs. (CVE-2018-16427)
Several buffer overflows when handling responses from a Gemsafe V1 Smartcard in gemsafe_get_cert_len in libopensc/pkcs15-gemsafeV1.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to cause a denial of service (application crash) or possibly have unspecified other impact.
(CVE-2018-16393)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
