Linux Distros Unpatched Vulnerability : CVE-2018-7184

high Nessus Plugin ID 260303

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the received timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704. (CVE-2018-7184)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
