GNU Binutils Dynamic Relocation Allocation elfxx-x86.c elf_x86_allocate_dynrelocs null pointer dereference

A vulnerability was detected in GNU Binutils 2.47. Affected by this vulnerability is the function elf_x86_allocate_dynrelocs of the file bfd/elfxx-x86.c of the component Dynamic Relocation Allocation. The manipulation results in null pointer dereference. The attack requires a local approach. The exploit is now public and may be used. Upgrading to version 2.48 addresses this issue.
