Vulnerability Details

CVEID: CVE-2019-1559
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by the failure to immediately close the TCP connection
after the hosts encounter a zero-length record with valid padding. An attacker
could exploit this vulnerability using a 0-byte record padding-oracle attack to
decrypt traffic.
CVSS Base Score: 5.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
157514 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N)

CVEID: CVE-2019-5737
DESCRIPTION: Node.js is vulnerable to a denial of service. By establishing an
HTTP or HTTPS connection in keep-alive mode and sending headers very slowly to
force the connection and associated resources to stay alive for a long period
of time, a remote attacker could exploit this vulnerability to consume all
available resources.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
158093 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2019-5739
DESCRIPTION: Node.js is vulnerable to a denial of service. By establishing an
HTTP or HTTPS connection in keep-alive mode forcing the connection to remain
open and inactive for up to 2 minutes, a remote attacker could exploit this
vulnerability to consume all available resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
158096 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
