How to fix?

There is no fixed version for RHEL:8 binutils.

NVD Description

Note: Versions mentioned in the description apply only to the upstream binutils package and not the binutils package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

An issue was discovered in elf_link_input_bfd in elflink.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. There is a NULL pointer dereference in elf_link_input_bfd when used for finding STT_TLS symbols without any TLS section. A specially crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld.
