Descriptions

Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow.

Expat permite a atacantes dependientes del contexto provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de un documento de entrada mal formado, lo que desencadena un desbordamiento de buffer.

An out-of-bounds read flaw was found in the way Expat processed certain input. A remote attacker could send specially crafted XML that, when parsed by an application using the Expat library, would cause that application to crash or, possibly, execute arbitrary code with the permission of the user running the application.
