A crafted image file can trigger `stbi__load_gif_main_outofmem` attempt to double-free the out variable. This happens in `stbi__load_gif_main` because when the `layers * stride` value is zero the behavior is implementation defined, but common that realloc frees the old memory and returns null pointer. Since it attempts to double-free the memory a few lines below the first \u201cfree\u201d, the issue can be potentially exploited only in a multi-threaded environment. In the worst case this may lead to code execution."}, {"lang": "es", "value": "stb_image es una librer\u00eda con licencia MIT de un solo archivo para procesar im\u00e1genes. Un archivo de imagen manipulado puede provocar que `stbi__load_gif_main_outofmem` intente liberar dos veces la variable out. Esto sucede en `stbi__load_gif_main` porque cuando el valor de `layers * stride` es cero, el comportamiento est\u00e1 definido por la implementaci\u00f3n, pero es com\u00fan que la realloc libere la memoria antigua y devuelva un puntero nulo. Dado que intenta liberar dos veces la memoria unas pocas l\u00edneas debajo de la primera \"free\", el problema s\u00f3lo puede explotarse en un entorno de subprocesos m\u00faltiples.
