The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1041-1 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)
An issue was discovered in OpenSC through 0.19.0 and 0.20.x through 0.20.0-rc3. libopensc/card-cac1.c mishandles buffer limits for CAC certificates. (CVE-2019-19481)
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)
sc_context_create in ctx.c in libopensc in OpenSC 0.19.0 has a memory leak, as demonstrated by a call from eidenv. (CVE-2019-6502)
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)

A use after return issue was found in Opensc before version 0.22.0 in insert_pin function that could potentially crash programs using the library. (CVE-2021-42780)
Heap buffer overflow issues were found in Opensc before version 0.22.0 in pkcs15-oberthur.c that could potentially crash programs using the library. (CVE-2021-42781)
Stack buffer overflow issues were found in Opensc before version 0.22.0 in various places that could potentially crash programs using the library. (CVE-2021-42782)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
