      "value": "The bfd_cache_close function in bfd/cache.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29 and earlier, allows remote attackers to cause a heap use after free and possibly achieve code execution via a crafted nested archive file. This issue occurs because incorrect functions are called during an attempt to release memory. The issue can be addressed by better input validation in the bfd_generic_archive_p function in bfd/archive.c."

      "value": "La funci\u00f3n bfd_cache_close en bfd/cache.c de la librer\u00eda Binary File Descriptor (BFD), tambi\u00e9n llamada libbfd, tal y como se distribuye en GNU Binutils 2.29 y anteriores, permite que atacantes remotos provoquen un uso de memoria din\u00e1mica antes de liberaci\u00f3n y, probablemente, logren ejecutar c\u00f3digo a trav\u00e9s de un archivo anidado manipulado. Esto ocurre debido a que se llama a funciones incorrectas mientras se intenta liberar memoria. Este problema puede afrontarse mejorando la validaci\u00f3n de entradas en la funci\u00f3n bfd_generic_archive_p, en bfd/archive.c."
