(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."
