Descriptions

OpenDMARC through 1.3.2 and 1.4.x through 1.4.0-Beta1 has improper null termination in the function opendmarc_xml_parse that can result in a one-byte heap overflow in opendmarc_xml when parsing a specially crafted DMARC aggregate report. This can cause remote memory corruption when a '\0' byte overwrites the heap metadata of the next chunk and its PREV_INUSE flag.

OpenDMARC versiones hasta 1.3.2 y versiones desde 1.4.x hasta 1.4.0-Beta1, presenta una terminación nula inapropiada en la función opendmarc_xml_parse que puede resultar en un desbordamiento de la pila por un byte en opendmarc_xml al analizar un reporte agregado DMARC especialmente diseñado. Esto puede causar daños en la memoria remota cuando un byte "\0" sobrescribe los metadatos de la pila del siguiente fragmento y su flag PREV_INUSE
