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).

The remote NewStart CGSL host, running version MAIN 6.02, has raptor2 packages installed that are affected by multiple vulnerabilities:

  - 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-2017-18926)

  - A malformed input file can lead to a segfault due to an out of bounds array access in     raptor_xml_writer_start_element_common. (CVE-2020-25713)

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

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2021:1842 advisory.

  - A malformed input file can lead to a segfault due to an out of bounds array access in     raptor_xml_writer_start_element_common. (CVE-2020-25713)
