Synopsis
The remote machine is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version MAIN 4.05, has dhcp packages installed that are affected by multiple vulnerabilities:- An out-of-bound memory access flaw was found in the way dhclient processed a DHCP response packet. A malicious DHCP server could potentially use this flaw to crash dhclient processes running on DHCP client machines via a crafted DHCP response packet. (CVE-2018-5732)
- A denial of service flaw was found in the way dhcpd handled reference counting when processing client requests. A malicious DHCP client could use this flaw to trigger a reference count overflow on the server side, potentially causing dhcpd to crash, by sending large amounts of traffic. (CVE-2018-5733)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
