Descriptions
xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs.
El archivo xmlparse.c en Expat (tambiƩn se conoce como libexpat) versiones anteriores a 2.4.5, permite a atacantes insertar caracteres separadores de espacios de nombres en URIs de espacios de nombres
A flaw was found in expat. Passing one or more namespace separator characters in the "xmlns[:prefix]" attribute values made expat send malformed tag names to the XML processor on top of expat. This issue causes arbitrary code execution depending on how unexpected cases are handled inside the XML processor.
