Package        : elfutils
Version        : 0.176-1.1+deb10u1
CVE ID         : CVE-2020-21047


An issue has been found in elfutils, a collection of utilities to handle 
ELF objects.
Due to missing bound checks and reachable asserts, an attacker can 
use crafted elf files to trigger application crashes that result in 
denial-of-services.

For Debian 10 buster, this problem has been fixed in version
0.176-1.1+deb10u1.

We recommend that you upgrade your elfutils packages.
