Upgrade Debian:unstable elfutils to version 0.168-0.2 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.
The __libelf_set_rawdata_wrlock function in elf_getdata.c in elfutils before 0.168 allows remote attackers to cause a denial of service (crash) via a crafted (1) sh_off or (2) sh_size ELF header value, which triggers a memory allocation failure.
