Descriptions

Buffer overflow in the vararg functions in ldo.c in Lua 5.1 through 5.2.x before 5.2.3 allows context-dependent attackers to cause a denial of service (crash) via a small number of arguments to a function with a large number of fixed arguments.

Desbordamiento de buffer en las funciones vararg en ldo.c en Lua 5.1 hasta 5.2.x anterior a 5.2.3 permite a atacantes dependientes de contexto causar una denegación de servicio (caída) a través de un número pequeño de argumentos en una función con un número grande de argumentos fijos.

A heap-based overflow vulnerability was found in the way Lua, a simple, extensible, embeddable programming language, handles varargs functions with many fixed parameters called with few arguments, leading to application crashes or, potentially, arbitrary code execution.
