Descriptions

An issue in the component luaG_runerror of Lua v5.4.4 and below leads to a heap-buffer overflow when a recursive error occurs.

Un problema en el componente luaG_runerror de Lua versiones v5.4.4 y posteriores, conlleva a un desbordamiento del búfer de la pila cuando es producido un error recursivo

A vulnerability was found in Lua. During error handling, the luaG_errormsg() component uses slots from EXTRA_STACK. Some errors can recur such as a string overflow while creating an error message in 'luaG_runerror', or a C-stack overflow before calling the message handler, causing a crash that leads to a denial of service.
