Details

A weakness has been identified in GNU Binutils 2.47. This impacts the function elf_link_add_object_symbols of the file bfd/elflink.c. Executing a manipulation can lead to null pointer dereference. The attack needs to be launched locally. The exploit has been made available to the public and could be used for attacks.
