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.

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