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-2022-4450, CVE-2022-4304, CVE-2023-0215, CVE-2023-0286

Vulnerability Details

CVEID:CVE-2022-4450
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a double-free error related to the improper handling of specific PEM data by the PEM_read_bio_ex() function. By sending specially crafted PEM files for parsing, a remote attacker could exploit this vulnerability to cause the system to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246615 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-2022-4304
**DESCRIPTION:**OpenSSL could allow a remote attacker to obtain sensitive information, caused by a timing-based side channel in the RSA Decryption implementation. By sending an overly large number of trial messages for decryption, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246612 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-2023-0215
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a use-after-free error related to the incorrect handling of streaming ASN.1 data by the BIO_new_NDEF function. A remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246614 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-2023-0286
**DESCRIPTION:**OpenSSL is vulnerable to a denial of service, caused by a type confusion error related to X.400 address processing inside an X.509 GeneralName. By passing arbitrary pointers to a memcmp call, a remote attacker could exploit this vulnerability to read memory contents or cause a denial of service.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246611 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H)
