It may look like `stbi__load_gif_main` doesn\u2019t give guarantees about the content of output value `*delays` upon failure. Although it sets `*delays` to zero at the beginning, it doesn\u2019t do it in case the image is not recognized as GIF and a call to `stbi__load_gif_main_outofmem` only frees possibly allocated memory in `*delays` without resetting it to zero. Thus it would be fair to say the caller of `stbi__load_gif_main` is responsible to free the allocated memory in `*delays` only if `stbi__load_gif_main` returns a non null value. However at the same time the function may return null value, but fail to free the memory in `*delays` if internally `stbi__convert_format` is called and fails. Thus the issue may lead to a memory leak if the caller chooses to free `delays` only when `stbi__load_gif_main` didn\u2019t fail or to a double-free if the `delays` is always freed"}, {"lang": "es", "value": "stb_image es una librer\u00eda con licencia MIT de un solo archivo para procesar im\u00e1genes. Puede parecer que `stbi__load_gif_main` no ofrece garant\u00edas sobre el contenido del valor de salida `*delays` en caso de falla. Aunque establece `*delays` en cero al principio, no lo hace en caso de que la imagen no se reconozca como GIF y una llamada a `stbi__load_gif_main_outofmem` solo libera la memoria posiblemente asignada en `*delays` sin restablecerla a cero. Por lo tanto, ser\u00eda justo decir que la persona que llama a `stbi__load_gif_main` es responsable de liberar la memoria asignada en `*delays` solo si `stbi__load_gif_main` devuelve un valor no nulo. Sin embargo, al mismo tiempo, la funci\u00f3n puede devolver un valor nulo, pero no puede liberar la memoria en `*delays` si internamente se llama a `stbi__convert_format` y falla. Por lo tanto, el problema puede provocar una p\u00e9rdida de memoria si la persona que llama elige liberar los \"delays\" solo cuando \"stbi__load_gif_main\" no fall\u00f3 o una doble liberaci\u00f3n si los \"delays\" siempre se liberan."}], "lastModified": "2023-11-04T06:15:53.383", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:nothings:stb_image.h:2.28:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "76840B8F-81FC-4BC6-A92C-EBB978741DAB"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
