Ubuntu Security Notice USN-3670-1
June 05, 2018

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:
  elfutils                        0.165-3ubuntu1.1
  libasm1                         0.165-3ubuntu1.1
  libdw1                          0.165-3ubuntu1.1
  libelf1                         0.165-3ubuntu1.1

Ubuntu 14.04 LTS:
  elfutils                        0.158-0ubuntu5.3
  libasm1                         0.158-0ubuntu5.3
  libdw1                          0.158-0ubuntu5.3
  libelf1                         0.158-0ubuntu5.3

In general, a standard system update will make all the necessary changes.
