Vulnerability Details

CVEID:CVE-2021-36090
**DESCRIPTION:**Apache Commons Compress is vulnerable to a denial of service, caused by an out-of-memory error when large amounts of memory are allocated. By reading a specially-crafted ZIP archive, a remote attacker could exploit this vulnerability to cause a denial of service condition against services that use Compress’ zip package.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/205310 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-2021-20479
**DESCRIPTION:**IBM Cloud Pak System uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/197498 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)

Affected Products and Versions

Affected Product(s) Version(s)
IBM Cloud Pak System V2.3.0 - V2.3.3.3 Interim Fix 1

Remediation/Fixes

For unsupported version/release/platform IBM recommends upgrading to a fixed, supported version of the product.

Cloud Pak System uses weaker than expected cryptographic algorithms during negotiation, which could allow an attacker to decrypt sensitive information. TLS 1.0 and 1.1 is not disabled by default. Cloud Pak System v2.3.3.4 supports TLS1.2 and enables it by default.

For IBM Cloud Pak System V2.3.0 through to V2.3.3.3 Interim Fix 1 upgrade to V2.3.3.4 at Fix Central
