Security Bulletin: Multiple vulnerabilities in OpenSSL affects IBM Rational ClearCase

Summary

OpenSSL vulnerabilities were disclosed by the OpenSSL Project. OpenSSL is used by IBM Rational ClearCase. [CVE-2023-5363, CVE-2023-4807, CVE-2023-3446]

Vulnerability Details

CVEID:CVE-2023-5363
**DESCRIPTION:**OpenSSL could allow a remote attacker to obtain sensitive information, caused by an incorrect cipher key and IV length processing during the initialisation of some symmetric ciphers. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/269418 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)

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-2023-3446
**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 using long DH keys or parameters, 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/261026 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)
