The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4796-1 advisory.

    Alexander Minozhenko and James Bunton discovered that Node.js did not properly handle wildcards in name     fields of X.509 TLS certificates. An attacker could use this vulnerability to execute a machine-in-the-     middle- attack. This issue only affected Ubuntu 14.04 ESM and 16.04 ESM. (CVE-2016-7099)

    It was discovered that Node.js incorrectly handled certain NAPTR responses. A remote attacker could     possibly use this issue to cause applications using Node.js to crash, resulting in a denial of service.
    This issue only affected Ubuntu 16.04 ESM. (CVE-2017-1000381)

    Nikita Skovoroda discovered that Node.js mishandled certain input, leading to an out of bounds write. An     attacker could use this vulnerability to cause a denial of service (crash) or possibly execute arbitrary     code. This issue only affected Ubuntu 18.04 ESM. (CVE-2018-12115)

    Arkadiy Tetelman discovered that Node.js improperly handled certain malformed HTTP requests. An attacker     could use this vulnerability to inject unexpected HTTP requests. This issue only affected Ubuntu 18.04     ESM. (CVE-2018-12116)

    Jan Maybach discovered that Node.js did not time out if incomplete HTTP/HTTPS headers were received. An     attacker could use this vulnerability to cause a denial of service by keeping HTTP/HTTPS connections alive     for a long period of time. This issue only affected Ubuntu 18.04 ESM. (CVE-2018-12122)

    Martin Bajanik discovered that the url.parse() method would return incorrect results if it received     specially crafted input. An attacker could use this vulnerability to spoof the hostname and bypass     hostname-specific security controls. This issue only affected Ubuntu 18.04 ESM. (CVE-2018-12123)

    It was discovered that Node.js is vulnerable to a DNS rebinding attack which could be exploited to perform     remote code execution. An attack is possible from malicious websites open in a web browser with network     access to the system running the Node.js process. This issue only affected Ubuntu 18.04 ESM.
    (CVE-2018-7160)

    It was discovered that the Buffer.fill() and Buffer.alloc() methods improperly handled certain inputs. An     attacker could use this vulnerability to cause a denial of service. This issue only affected Ubuntu 18.04     ESM. (CVE-2018-7167)

    Marco Pracucci discovered that Node.js mishandled HTTP and HTTPS connections. An attacker could use this     vulnerability to cause a denial of service. This issue only affected Ubuntu 18.04 ESM. (CVE-2019-5737)

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 number.

The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the K000137093 advisory.

  - Calling Buffer.fill() or Buffer.alloc() with some parameters can lead to a hang which could result in a     Denial of Service. In order to address this vulnerability, the implementations of Buffer.alloc() and     Buffer.fill() were updated so that they zero fill instead of hanging in these cases. All versions of     Node.js 6.x (LTS Boron), 8.x (LTS Carbon), and 9.x are vulnerable. All versions of Node.js 10.x     (Current) are NOT vulnerable. (CVE-2018-7167)

  - In all versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0 when used with UCS-2 encoding (recognized by     Node.js under the names `'ucs2'`, `'ucs-2'`, `'utf16le'` and `'utf-16le'`), `Buffer#write()` can be abused     to write outside of the bounds of a single `Buffer`. Writes that start from the second-to-last position of     a buffer cause a miscalculation of the maximum length of the input bytes to be written. (CVE-2018-12115)

  - Node.js: All versions prior to Node.js 6.15.0 and 8.14.0: HTTP request splitting: If Node.js can be     convinced to use unsanitized user-provided Unicode data for the `path` option of an HTTP request, then     data can be provided which will trigger a second, unexpected, and user-defined HTTP request to made to the     same server. (CVE-2018-12116)

Node.js reports :

Updates are now available for all active Node.js release lines. These include fixes for the vulnerabilities identified in the initial announcement. They also include upgrades of Node.js 6 and 8 to OpenSSL 1.0.2q, and upgrades of Node.js 10 and 11 to OpenSSL 1.1.0j.

We recommend that all Node.js users upgrade to a version listed below as soon as possible. Debugger port 5858 listens on any interface by default (CVE-2018-12120) All versions of Node.js 6 are vulnerable and the severity is HIGH. When the debugger is enabled with node --debug or node debug, it listens to port 5858 on all interfaces by default.
This may allow remote computers to attach to the debug port and evaluate arbitrary JavaScript. The default interface is now localhost.
It has always been possible to start the debugger on a specific interface, such as node --debug=localhost. The debugger was removed in Node.js 8 and replaced with the inspector, so no versions from 8 and later are vulnerable. Denial of Service with large HTTP headers (CVE-2018-12121) All versions of 6 and later are vulnerable and the severity is HIGH. By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer.

The total size of HTTP headers received by Node.js now must not exceed 8192 bytes. 'Slowloris' HTTP Denial of Service (CVE-2018-12122) All versions of Node.js 6 and later are vulnerable and the severity is LOW. An attacker can cause a Denial of Service (DoS) by sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time. Attack potential is mitigated by the use of a load balancer or other proxy layer.

A timeout of 40 seconds now applies to servers receiving HTTP headers.
This value can be adjusted with server.headersTimeout. Where headers are not completely received within this period, the socket is destroyed on the next received chunk. In conjunction with server.setTimeout(), this aids in protecting against excessive resource retention and possible Denial of Service. Hostname spoofing in URL parser for JavaScript protocol (CVE-2018-12123) All versions of Node.js 6 and later are vulnerable and the severity is LOW. If a Node.js application is using url.parse() to determine the URL hostname, that hostname can be spoofed by using a mixed case 'javascript:' (e.g. 'javAscript:') protocol (other protocols are not affected). If security decisions are made about the URL based on the hostname, they may be incorrect. HTTP request splitting (CVE-2018-12116) Node.js 6 and 8 are vulnerable and the severity is MEDIUM. If Node.js can be convinced to use unsanitized user-provided Unicode data for the path option of an HTTP request, then data can be provided which will trigger a second, unexpected, and user-defined HTTP request to made to the same server. OpenSSL Timing vulnerability in ECDSA signature generation (CVE-2018-0735) The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a timing side-channel attack. An attacker could use variations in the signing algorithm to recover the private key. OpenSSL Timing vulnerability in DSA signature generation (CVE-2018-0734) The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side-channel attack. An attacker could use variations in the signing algorithm to recover the private key. OpenSSL Microarchitecture timing vulnerability in ECC scalar multiplication (CVE-2018-5407) OpenSSL ECC scalar multiplication, used in e.g. ECDSA and ECDH, has been shown to be vulnerable to a microarchitecture timing side-channel attack. An attacker with sufficient access to mount local timing attacks during ECDSA signature generation could recover the private key.
