Descriptions

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, does not validate the DW_AT_name data type, which allows remote attackers to cause a denial of service (bfd_hash_hash NULL pointer dereference, or out-of-bounds access, and application crash) via a crafted ELF file, related to scan_unit_for_symbols and parse_comp_unit.

La función dwarf2.c en la biblioteca Binary File Descriptor (BFD), conocida como libbfd, tal y como se distribuye en GNU Binutils 2.29, no valida el tipo de dato DW_AT_name, que permite que atacantes remotos provoquen una denegación de servicio (desreferencia de puntero NULL bfd_hash_hash o acceso fuera de límites y cierre inesperado de la aplicación) mediante un archivo ELF manipulado, relacionado con scan_unit_for_symbols y parse_comp_unit.
