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 raptorntriplesparseterminternal().

In Raptor RDF Syntax Library through 2.0.16, there is an integer underflow when normalizing a URI with the turtle parser in raptorurinormalizepath().

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.

raptorxmlwriterstartelementcommon in raptorxmlwriter.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 raptorqnameformatasxml).
