Releases

• Ubuntu 18.10
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• 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.
