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.

Affected Products and Versions

For earlier and unsupported versions of the products, IBM recommends upgrading to a fixed, supported version of the product.

Remediation/Fixes

The recommended solution is to apply the Interim Fix (iFix) or Cumulative Fix (CF) containing APAR JR63217 as soon as practical:

• IBM Business Automation Workflow (including fix for IBM Business Process Manager V8.6.0.0 2018.03)
• IBM Business Process Manager Advanced
• IBM Business Process Manager Standard
• IBM Business Process Manager Express

For IBM Business Automation Workflow V18.0, V19.0, and V20.0
· Upgrade to minimal cumulative fix levels as required by iFix and then apply iFix JR63217
--OR–
· Apply cumulative fix Business Automation Workflow V20.0.0.2 or later

For IBM Business Process Manager V8.6
· Upgrade to minimal cumulative fix levels as required by iFix and then apply iFix JR63217
--OR–
· Upgrade to Business Automation Workflow V20.0.0.2 or later

For IBM BPM V8.5
· Upgrade to IBM BPM V8.5.7, apply Cumulative Fix 2017.06 and then apply iFix JR63217
