Summary

A number of security vulnerabilities have been discovered in the OpenSSL libraries included in IBM Sterling Connect:Express for UNIX.

Vulnerability Details

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: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246612 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/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.
