Security Bulletin: Vulnerabilities in OpenSSL, Linux Kernel might affect IBM Storage Copy Data Management

Summary

IBM Storage Copy Data Management can be affected by vulnerabilities in OpenSSL and Linux Kernel. An attacker could exploit these vulnerabilities to obtain kernel internal information, gain elevated privileges, and cause a denial of service conditions, as described by the CVEs in the “Vulnerability Details” section.

Vulnerability Details

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)

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)

CVEID:CVE-2023-4622
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a use-after-free flaw in the af_unix component. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/265425 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-2023-2162
**DESCRIPTION:**Linux Kernel could allow a local attacker to obtain sensitive information, caused by a use-after-free flaw in the iscsi_sw_tcp_session_create function in drivers/scsi/iscsi_tcp.c in the SCSI sub-component. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain kernel internal information, and use this information to launch further attacks against the affected system.
CVSS Base score: 6.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/253490 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

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.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2023-5633
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a use-after-free flaw in the way memory objects were handled. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/269432 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-2023-42753
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to execute arbitrary code on the system, caused by an integer underflow due to an array indexing issue in the netfilter ipset subsystem. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition.
CVSS Base score: 7.8
