Security Bulletin: Vulnerabilities in Linux Kernel and OpenSSL may affect IBM Spectrum Copy Data Management

Vulnerability Details

CVEID:   CVE-2022-1729
DESCRIPTION:   Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a race condition in the perf subsystem. By sending specially-crafted syscalls, an authenticated attacker could exploit this vulnerability to gain elevated privileges to root.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/227038 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-2021-3759
DESCRIPTION:   Linux Kernel is vulnerable to a denial of service, caused by a memory overflow in the ipc function in the memcg subsystem. By sending a specially-crafted request using the semget function, a local authenticated attacker could exploit this vulnerability to cause starve of the resources, and results in a denial of service condition.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/234232 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-2022-32250
DESCRIPTION:   Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a use-after-free write flaw in the netfilter subsystem. By executing a specially-crafted program, 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/228676 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-2022-2068
DESCRIPTION:   OpenSSL could allow a remote attacker to execute arbitrary commands on the system, caused by improper validation of user-supplied input by the c_rehash script. By sending a specially-crafted request using shell metacharacters, an attacker could exploit this vulnerability to execute arbitrary commands with the privileges of the script on the system.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/226018 for the current score.

CVEID:   CVE-2020-28915
DESCRIPTION:   Linux Kernel could allow a local attacker to obtain sensitive information, caused by a buffer over-read flaw in the fbcon code. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain kernel memory 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/191993 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-2022-2097
DESCRIPTION:   OpenSSL could allow a remote attacker to obtain sensitive information, caused by improper encryption of data by the AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation. 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: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/230425 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:   CVE-2022-1012
DESCRIPTION:   Linux Kernel could allow a remote attacker to obtain sensitive information, caused by a memory leak flaw in the TCP source port generation algorithm in the net/ipv4/tcp.c function. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information or cause a denial of service condition.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/230055 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)

CVEID:   CVE-2022-27666
DESCRIPTION:   Linux Kernel is vulnerable to a buffer overflow, caused by improper bounds checking by the ESP transformation in net/ipv4/esp4.c and net/ipv6/esp6.c. By sending a large message, a local attacker could overflow a buffer and execute arbitrary code on the system or gain elevated privileges in some configurations.
CVSS Base score: 8.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/222414 for the current score.
