Security Bulletin: Multiple vulnerabilities in Node.js affect IBM InfoSphere Information Server

Summary

Muiltiple vulnerabilities in Node.js that is used by IBM InfoSphere Information Server were addressed.

Vulnerability Details

CVEID:CVE-2021-22884
**DESCRIPTION:**Node.js is vulnerable to a denial of service, caused by an error when the allowlist includes “localhost6”. By controlling the victim’s DNS server or spoofing its responses, an attacker could exploit this vulnerability to bypass the DNS rebinding protection mechanism using the “localhost6” domain and cause a denial of service.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/197191 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H)

CVEID:CVE-2021-22883
**DESCRIPTION:**Node.js is vulnerable to a denial of service, caused by a file descriptor leak. By making multiple attempts to connect with an ‘unknownProtocol’, an attacker could exploit this vulnerability to lead to an excessive memory usage and cause the system to run out of memory.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/197190 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2021-23840
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by an integer overflow in CipherUpdate. By sending an overly long argument, an attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/196848 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-8201
**DESCRIPTION:**Node.js is vulnerable to HTTP request smuggling, caused by CR-to-Hyphen conversion. By sending specially crafted HTTP request headers, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/188591 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)

CVEID:CVE-2020-8252
**DESCRIPTION:**Node.js is vulnerable to a buffer overflow, caused by improper bounds checking by the libuv’s fs.realpath.native. By sending an overly long argument, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/188593 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2020-8265
**DESCRIPTION:**Node.js is vulnerable to a denial of service, caused by a use-after-free in TLSWrap within the TLS implementation. By writing to a TLS enabled socket, an attacker could exploit this vulnerability to corrupt memory and cause a denial of service.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/194101 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-8287
**DESCRIPTION:**Node.js is vulnerable to HTTP request smuggling. By sending specially crafted HTTP request headers, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/194100 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)

CVEID:CVE-2020-1971
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference. If the GENERAL_NAME_cmp function contain an EDIPARTYNAME, an attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/192748 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-8277
**DESCRIPTION:**Node.js is vulnerable to a denial of service. By getting the application to resolve a DNS record with a larger number of responses, an attacker could exploit this vulnerability to trigger a DNS request for a host of their choice resulting in a denial of service.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/191755 for the current score.
