CVE-2016-0718

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.

It was discovered that the Expat code in XML-RPC for C and C++ unexpectedly called srand in certain circumstances. This could reduce the security of calling applications. It was discovered that the Expat code in XML-RPC for C and C++ incorrectly handled seeding the random number generator. A remote attacker could possibly use this issue to cause a denial of service. Gustavo Grieco discovered that the Expat code in XML-RPC for C and C++ incorrectly handled malformed XML data. If a user or application linked against XML-RPC for C and C++ were tricked into opening a crafted XML file, an attacker could cause a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
