    - CVE-2017-18926 (arbitrary code execution)
    raptor_xml_writer_start_element_common in raptor_xml_writer.c in Raptor
    RDF Syntax Library 2.0.15 miscalculates the maximum nspace declarations
    for the XML writer, leading to heap-based buffer overflows (sometimes
    seen in raptor_qname_format_as_xml).
    - CVE-2020-25713 (arbitrary code execution)
    A malformed input file can lead to a segfault due to an out of bounds
    array access in raptor_xml_writer_start_element_common.
    A maliciously crafted RDF file can crash the application or execute
    arbitrary code.
