        A heap use after free issue was found in sc_file_valid().

    CVE-2021-42780

        A use after return issue was found in the insert_pin() function,         which could potentially crash programs using the library.

    CVE-2024-45619

        Matteo Marini discovered multiple incorrect handling of length of         buffers or files in libopensc, which could result in application         crash or information leak.  When buffers are partially filled with         data, uninitialized parts of the buffer may be incorrectly accessed.

    CVE-2024-45620

        Matteo Marini discovered multiple incorrect handling of length of         buffers or files in pkcs15init, which could result in application         crash or information leak.
