Descriptions

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (excessive memory allocation and application crash) via a crafted ELF file, as demonstrated by _bfd_elf_parse_attributes in elf-attrs.c and bfd_malloc in libbfd.c. This can occur during execution of nm.

La biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.30 y anteriores permite que atacantes remotos provoquen una denegación de servicio (asignación excesiva de memoria y cierre inesperado de la aplicación) mediante un archivo ELF manipulado. Esto queda demostrado por _bfd_elf_parse_attributes en elf-attrs.c y bfd_malloc en libbfd.c. Esto puede ocurrir durante la ejecución de nm.
