Descriptions

In Mini-XML (aka mxml) v2.12, there is a use-after-free in the mxmlAdd function of the mxml-node.c file. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted xml file, as demonstrated by mxmldoc.

En Mini-XML (también conocido como mxml) v2.12, hay un uso de memoria previamente liberada en la función mxmlAdd del archivo mxml-node.c. Los atacantes remotos podrían aprovechar esta vulnerabilidad para provocar una denegación de servicio (DoS) mediante un archivo xml manipulado, tal y como queda demostrado con mxmldoc.
