Details

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 was only fixed in Ubuntu 18.04 ESM. (

issue was only fixed in 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 was only fixed in 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 was only fixed in 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 was only fixed in 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 was only fixed in Ubuntu 18.04 ESM. (CVE-2019-5737)
