elfutils vulnerabilities
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in elfutils.

Software Description:
- elfutils: collection of utilities to handle ELF objects

Details:

It was discovered that elfutils incorrectly handled certain malformed
files. If a user or automated system were tricked into processing a
specially crafted file, elfutils could be made to crash or consume
resources, resulting in a denial of service.
