vulnerabilities as referenced in the USN-7670-1 advisory.

    It was discovered that the iputils ping utility incorrectly handled certain ICMP Echo Reply packets. A
    remote attacker could possibly use this issue to cause iputils to consume resources, leading to a denial
    of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
