CVE-2019-1559
CVE-2019-5737
CVE-2019-5739
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
