How to fix?

Upgrade Debian:unstable elfutils to version 0.176-1 or higher.

NVD Description

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

In elfutils 0.175, a negative-sized memcpy is attempted in elf_cvt_note in libelf/note_xlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash).
