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.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - opensc: Double free in coolkey_free_private_data in libopensc/card-coolkey.c (CVE-2019-20792)

  - opensc: buffer overrun vulnerability in pkcs15 cardos_have_verifyrc_package (CVE-2023-2977)

  - 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)

  - 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 heap double free issue was found in Opensc before version 0.22.0 in sc_pkcs15_free_tokeninfo.
    (CVE-2021-42778)

  - A heap use after free issue was found in Opensc before version 0.22.0 in sc_file_valid. (CVE-2021-42779)

  - 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)

  - A flaw was found in OpenSC packages that allow a potential PIN bypass. When a token/card is authenticated     by one process, it can perform cryptographic operations in other processes when an empty zero-length pin     is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small,     permanently connected tokens to computers. Additionally, the token can internally track login status. This     flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system     without the user's awareness. (CVE-2023-40660)

  - Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card     enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of     these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB     device or smart card to manipulate responses to APDUs. This manipulation can potentially allow compromise     key generation, certificate loading, and other card management operations during enrollment.
    (CVE-2023-40661)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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 ALAS2-2023-2102 advisory.

  - A heap use after free issue was found in Opensc before version 0.22.0 in sc_file_valid. (CVE-2021-42779)

  - 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)

  - A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15     cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context.
    The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is     wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. In     cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is     possible. (CVE-2023-2977)

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