Descriptions

The png_check_keyword function in pngwutil.c in libpng before 1.0.42, and 1.2.x before 1.2.34, might allow context-dependent attackers to set the value of an arbitrary memory location to zero via vectors involving creation of crafted PNG files with keywords, related to an implicit cast of the '\0' character constant to a NULL pointer. NOTE: some sources incorrectly report this as a double free vulnerability.

La funcion png_check_keyword en pngwutil.c en libpng anteriores a v1.0.42, v1.2.x anterior a v1.2.34, permitiría atacantes dependientes de contexto poner a cero el valor de una localización de memoria de su elección a través de vectores relacionados con la creación de ficheros PNG con palabras clave, relacionado con la asignación del valor '\0' a un puntero NULL. NOTA: Algunas fuentes informan incorrectamente que se trata de una vulnerabilidad de doble liberación.
