  - 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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

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

Note that Nessus relies on the presence of the package as reported by the vendor.

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)

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