F5 Networks BIG-IP : NTP vulnerability (K32262483)

high Nessus Plugin ID 105403

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The mx4200_send function in the legacy MX4200 refclock in NTP before 4.2.8p10 and 4.3.x before 4.3.94 does not properly handle the return value of the snprintf function, which allows local users to execute arbitrary code via unspecified vectors, which trigger an out-of-bounds memory write. (CVE-2017-6451)

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K32262483.
