Security Bulletin
Summary
Vulnerabilities in the Linux Kernel such as execution of arbitrary code, denial of service, bypassing security restrictions, and obtaining or disclosing of information may affect IBM Spectrum Protect Plus.
Vulnerability Details
CVEID: CVE-2020-25212
DESCRIPTION: Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a TOCTOU mismatch in the NFS client code. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code or corrupt memory.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/188137 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2020-24394
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to bypass security restrictions, caused by the lack of ACL support to the filesystems in fs/nfsd/vfs.c (in the NFS server). By sending a specially-crafted request, an attacker could exploit this vulnerability to set incorrect permissions on new filesystem objects.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/186968 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N)
CVEID: CVE-2019-20636
DESCRIPTION: Linux Linux could allow a local attacker to execute arbitrary code on the system, caused by an out-of-bounds write flaw in the input_set_keycode function. By using a specially-crafted keycode table, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 8.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/181202 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2020-12464
DESCRIPTION: Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a use-after-free flaw in the usb_sg_cancel function in drivers/usb/core/message.c. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 8.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/181213 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2020-14385
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a failure of the file system metadata validator in XFS. By sending a specially crafted request, a local attacker could exploit this vulnerability to cause the system to shutdown.
CVSS Base score: 4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/188394 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2020-14314
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a memory out-of-bounds read flaw. By sending a specially crafted request, a local attacker could exploit this vulnerability to cause the system to crash.
CVSS Base score: 4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/188395 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2020-10732
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by a flaw in the implementation of Userspace core dumps. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information or cause a program to crash.
CVSS Base score: 3.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/181554 for the current score.
