Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has NetworkManager packages installed that are affected by a vulnerability:

- It was discovered that systemd-network does not correctly keep track of a buffer size when constructing DHCPv6 packets. This flaw may lead to an integer underflow that can be used to produce an heap-based buffer overflow. A malicious host on the same network segment as the victim's one may advertise itself as a DHCPv6 server and exploit this flaw to cause a Denial of Service or potentially gain code execution on the victim's machine. (CVE-2018-15688)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL NetworkManager packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
