Security Bulletin: IBM Workload Automation is potentially affected by a vulnerability in OpenSSL that might cause Denial of Service

Summary

IBM Workload Automation is potentially affected by multiple vulnerabilities in OpenSSL that could cause Denial of Service (CVE-2023-4807, CVE-2023-3817)

Vulnerability Details

CVEID:CVE-2023-4807
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a state corruption flaw in the POLY1305 MAC (message authentication code) implementation, when running on newer X86_64 processors supporting the AVX512-IFMA instructions. A local authenticated attacker could exploit this vulnerability to cause an incorrect result of some application dependent calculations or a crash or in some cases gain complete control of the application process.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/265578 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2023-3817
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a flaw when using the DH_check(), DH_check_ex() or EVP_PKEY_param_check() functions to check a DH key or DH parameters. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause long delays, and results in a denial of service condition.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/262046 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
