Raptor

pgxconfig in the Raptor GFX configuration tool uses a relative path name for a system call to the "cp" program, which allows local users to execute arbitrary commands by modifying their path to point to an alternate "cp" program.

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).

pgxconfig in the Raptor GFX configuration tool allows local users to gain privileges via a symlink attack.
