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.

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)

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 : Denial of Service Vulnerability in HTTP/2 (CVE-2018-7161) All versions of 8.x and later are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node server providing an http2 server to crash. This can be accomplished by interacting with the http2 server in a manner that triggers a cleanup bug where objects are used in native code after they are no longer available. This has been addressed by updating the http2 implementation. Thanks to Jordan Zebor at F5 Networks for reporting this issue. Denial of Service, nghttp2 dependency (CVE-2018-1000168) All versions of 9.x and later are vulnerable and the severity is HIGH. Under certain conditions, a malicious client can trigger an uninitialized read (and a subsequent segfault) by sending a malformed ALTSVC frame. This has been addressed through an by updating nghttp2. Denial of Service Vulnerability in TLS (CVE-2018-7162) All versions of 9.x and later are vulnerable and the severity is HIGH. An attacker can cause a denial of service (DoS) by causing a node process which provides an http server supporting TLS server to crash. This can be accomplished by sending duplicate/unexpected messages during the handshake. This vulnerability has been addressed by updating the TLS implementation. Thanks to Jordan Zebor at F5 Networks all of his help investigating this issue with the Node.js team. Memory exhaustion DoS on v9.x (CVE-2018-7164) Versions 9.7.0 and later are vulnerable and the severity is MEDIUM. A bug introduced in 9.7.0 increases the memory consumed when reading from the network into JavaScript using the net.Socket object directly as a stream. An attacker could use this cause a denial of service by sending tiny chunks of data in short succession. This vulnerability was restored by reverting to the prior behaviour. Calls to Buffer.fill() and/or Buffer.alloc() may hang (CVE-2018-7167) 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.
