In Raptor RDF Syntax Library through 2.0.16, there is an integer underflow when normalizing a URI with the turtle parser in raptor_uri_normalize_path().
In Raptor RDF Syntax Library through 2.0.16, there is a heap-based buffer over-read when parsing triples with the nquads parser in raptor_ntriples_parse_term_internal().
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).
Redland Raptor (aka libraptor) before 2.0.7, as used by OpenOffice 3.3 and 3.4 Beta, LibreOffice before 3.4.6 and 3.5.x before 3.5.1, and other products, allows user-assisted remote attackers to read arbitrary files via a crafted XML external entity (XXE) declaration and reference in an RDF document.
