Descriptions

In the coff_pointerize_aux function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, an index is not validated, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted file, as demonstrated by objcopy of a COFF object.

En la función coff_pointerize_aux en coffgen.c en la biblioteca Binary File Descriptor (BFD), también conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30, no se valida un índice. Esto permite que atacantes remotos provoquen una denegación de servicio (fallo de segmentación) o que pueda provocar otro tipo de impacto sin especificar mediante un archivo manipulado, tal y como demuestra un objcopy de un objeto COFF.
