Description

The remote host is affected by the vulnerability described in GLSA-201612-04 (BusyBox: Multiple vulnerabilities)

Multiple vulnerabilities have been discovered in BusyBox. Please review
  the CVE identifiers referenced below for details.

Impact :

A remote attacker could possibly execute arbitrary code with the
  privileges of the process, or cause a Denial of Service condition.

Workaround :

There is no known workaround at this time. However, on Gentoo, the
  remote code execution vulnerability can be avoided if you don’t use
  BusyBox’s udhcpc or build the package without the “ipv6” USE flag
  enabled.
