Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several security vulnerabilities were fixed in opensc, a set of libraries and utilities to access smart cards that support cryptographic operations.

Out-of-bounds reads, buffer overflows and double frees could be used by attackers able to supply crafted smart cards to cause a denial of service (application crash) or possibly have unspecified other impact.

For Debian 8 'Jessie', these problems have been fixed in version 0.16.0-3+deb8u1.

We recommend that you upgrade your opensc packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote NewStart CGSL host, running version MAIN 6.02, has opensc packages installed that are affected by multiple vulnerabilities:

  - 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)

  - 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 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)

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of opensc installed on the remote host is prior to 0.19.0-5. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2262 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)

    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)

    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)

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5281-1 advisory.

    It was discovered that some OpenSC smart card drivers mishandled memory when performing certain decoding     operations. An attacker could possibly use this issue to cause a denial of service or other unspecified     impact. This issue only affected Ubuntu 16.04 ESM and Ubuntu 18.04 ESM. (CVE-2019-15945, CVE-2019-15946)

    It was discovered that some OpenSC smart card drivers had buffer overflow vulnerabilities. An attacker     could possibly use this issue to cause a denial of service or other unspecified impact. (CVE-2020-26570,     CVE-2020-26571, CVE-2020-26572)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This update for opensc fixes the following issues :

CVE-2020-26571: gemsafe GPK smart card software driver stack-based buffer overflow (bsc#1177380)

CVE-2019-15946: out-of-bounds access of an ASN.1 Octet string in asn1_decode_entry (bsc#1149747)
