elfutils vulnerabilities

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

  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS

Summary

elfutils could be made to crash or consume resources if it opened a specially crafted file.

Software Description

  • elfutils - collection of utilities to handle ELF objects

Details

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