"value": "An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. An invalid memory address dereference was discovered in read_reloc in reloc.c. The vulnerability causes a segmentation fault and application crash, which leads to denial of service, as demonstrated by objdump, because of missing _bfd_clear_contents bounds checking."

Se ha descubierto una desreferencia de direcci\u00f3n de memoria inv\u00e1lida en read_reloc en reloc.c. La vulnerabilidad provoca un error de segmentaci\u00f3n y el cierre inesperado de la aplicaci\u00f3n, lo que da lugar a una denegaci\u00f3n de servicio. Esto queda demostrado por objdump debido a la falta de comprobaci\u00f3n de l\u00edmites de _bfd_clear_contents."
