Vulnerability Details

CVEID: CVE-2018-7167 DESCRIPTION: Node.js is vulnerable to a denial of service. By invoking Buffer.fill() or Buffer.alloc() , a remote attacker could exploit this vulnerability to cause the application to hang.
CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/144740&gt; 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)

CVEID: CVE-2018-7164 DESCRIPTION: Node.js is vulnerable to a denial of service, caused by an error when reading from the network into JavaScript using the net.Socket object directly as a stream. By sending tiny chunks of data in short succession, a remote attacker could exploit this vulnerability to cause the application to exhaust all memory resources.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/144739&gt; 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:L)

CVEID: CVE-2018-7162 DESCRIPTION: Node.js is vulnerable to a denial of service. By sending duplicate/unexpected messages during the handshake, a remote attacker could exploit this vulnerability to cause the node server providing an http server supporting TLS server to crash.
CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/144738&gt; 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)

CVEID: CVE-2018-1000168 DESCRIPTION: nghttp2 is vulnerable to a denial of service, caused by a NULL pointer dereference. By sending a specially-crafted packet, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/141584&gt; 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:L)

CVEID: CVE-2018-7161 DESCRIPTION: Node.js is vulnerable to a denial of service, caused by an error within the http2 implementation. By interacting with the http2 server in an insecure manner, a remote attacker could exploit this vulnerability to cause the node server providing an http2 server to crash.
CVSS Base Score: 7.5
