Descriptions
Ruby through 2.2.7, 2.3.x through 2.3.4, and 2.4.x through 2.4.1 can expose arbitrary memory during a JSON.generate call. The issues lies in using strdup in ext/json/ext/generator/generator.c, which will stop after encountering a '\0' byte, returning a pointer to a string of length zero, which is not the length stored in space_len.
Ruby hasta la versión 2.2.7, 2.3.x hasta la 2.3.4, y 2.4.x hasta la 2.4.1 puede exponer memoria arbitraria durante una llamada JSON.generate. Los problemas surgen al usar strdup en ext/json/ext/generator/generator.c, el cual se detendría después de encontrar un byte '\0', devolviendo un puntero a un string de longitud cero, que no es la longitud almacenada en space_len.
A buffer overflow vulnerability was found in the JSON extension of ruby. An attacker with the ability to pass a specially crafted JSON input to the extension could use this flaw to expose the interpreter's heap memory.
