Summary

OpenSSL vulnerabilities were disclosed by the OpenSSL Project. OpenSSL is used by IBM DevOps Code ClearCase. [CVE-2023-6237, CVE-2023-6129, CVE-2023-5678, CVE-2024-0727]

Vulnerability Details

CVEID:CVE-2023-6237
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a flaw in the handling of RSA public keys by the EVP_PKEY_public_check() function. By persuading a victim to sue a specially crafted RSA public keys for verification, a remote attacker could exploit this vulnerability to cause long delays, and results in a denial of service condition.
CVSS Base score: 3.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/279450 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L)

CVEID:CVE-2023-6129
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a flaw in the POLY1305 MAC (message authentication code) implementation. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/278934 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-5678
**DESCRIPTION:**Openssl is vulnerable to a denial of service, caused by a flaw when using DH_generate_key() function to generate an X9.42 DH key. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/270771 for the current score.
