How to fix?

Upgrade elfutils to version 0.176 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-bounds Read. In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32_xlatetom in elf32_xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because ebl_core_note does not reject malformed core file notes.
