Summary

IBM MQ Appliance has addressed multiple open source vulnerabilities.

Vulnerability Details

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.

CVEID:CVE-2024-28834
**DESCRIPTION:**GnuTLS could allow a remote authenticated attacker to obtain sensitive information, caused by a flaw in the ECDSA code. By utilize Minerva attack techniques, an attacker could exploit this vulnerability to obtain private key information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/286142 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2023-1073
**DESCRIPTION:**Linux Kernel could allow a physical authenticated attacker to gain elevated privileges on the system, caused by a memory corruption flaw in the human interface device (HID) subsystem. By using a specially crafted USB device , an attacker could exploit this vulnerability to gain elevated privileges or cause a denial of service condition.
CVSS Base score: 6.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/251322 for the current score.
CVSS Vector: (CVSS:3.0/AV:P/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2023-1079
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by a use-after-free flaw flaw in the asus_kbd_backlight_set function. By using a specially-crafted USB device, a physical attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 4.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/248808 for the current score.
CVSS Vector: (CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-1206
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by a flaw in the IPv6 connection lookup table. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause the CPU usage to increase, and results in a denial of service condition.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/259617 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-4132
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by a use-after-free flaw in the siano smsusb module. By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/262540 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-5388
**DESCRIPTION:**Red Hat Enterprise Linux could allow a remote authenticated attacker to obtain sensitive information, caused by an observable timing discrepancy in the numerical library used in NSS for RSA cryptography. An attacker could exploit this vulnerability to obtain sensitive information and use this information to conduct Bleichenbacher or Manger attacks against the affected system.
CVSS Base score: 6.5
