      "value": "A Null Pointer Dereference vulnerability exits in ffjpeg d5cfd49 (2021-12-06) in bmp_load(). When the size information in metadata of the bmp is out of range, it returns without assign memory buffer to `pb->pdata` and did not exit the program. So the program crashes when it tries to access the pb->data, in jfif_encode() at jfif.c:763. This is due to the incomplete patch for CVE-2020-13438."

Cuando la informaci\u00f3n del tama\u00f1o en los metadatos del bmp est\u00e1 fuera de rango, devuelve sin asignar memoria intermedia a \"pb-)pdata\" y no sale del programa.
