Summary

IBM Security Guardium has addressed the following vulnerabilities.

Vulnerability Details

CVEID: CVE-2018-3639
DESCRIPTION: Multiple Intel CPU''s could allow a local attacker to obtain
sensitive information, caused by utilizing sequences of speculative execution
and speculative execution of memory reads before the addresses of all prior
memory writes are known. By conducting targeted cache side-channel attacks, an
attacker could exploit this vulnerability to bypass security restrictions and
gain read access to privileged memory. Note: This vulnerability is the
Speculative Store Bypass (SSB), also known as Variant 4 or "SpectreNG".
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
143569 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N)

CVEID: CVE-2018-1000004
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a
race condition in the sound system. A remote attacker could exploit this
vulnerability to cause the system to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
137756 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2018-10901
DESCRIPTION: Linux Kernel could allow a remote attacker to gain elevated
privileges on the system, caused by the failure to restore the GDT.LIMIT to
the previous host value by the KVM virtualization subsystem. By sending a
specially-crafted argument, an attacker could exploit this vulnerability to
gain elevated privileges.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
147862 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2018-7566
DESCRIPTION: Linux Kernel is vulnerable to a buffer overflow, caused by
improper bounds checking by user-supplied input. By using an
SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq, a local
authenticated attacker could overflow a buffer and execute arbitrary code on
the system.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
141112 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2018-3693
DESCRIPTION: Intel Haswell Xeon, AMD PRO and ARM Cortex A57 CPUs could allow a
local authenticated attacker to obtain sensitive information, caused by a
bounds check bypass in the CPU speculative branch instruction execution
feature. By conducting targeted cache side-channel attacks, an attacker could
exploit this vulnerability to cross the syscall boundary and read data from
the CPU virtual memory.
CVSS Base Score: 7.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
146191 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N)

CVEID: CVE-2018-3646
DESCRIPTION: Multiple Intel CPU''s could allow a local attacker to obtain
sensitive information, caused by a flaw in the CPU speculative branch
instruction execution feature. By conducting targeted cache side-channel
attacks and via a terminal page fault, an attacker with guest OS privilege
could exploit this vulnerability to leak information residing in the L1 data
cache and read data belonging to different security contexts.
CVSS Base Score: 7.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
148319 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N)

CVEID: CVE-2018-3620
DESCRIPTION: Multiple Intel CPU''s could allow a local attacker to obtain
sensitive information, caused by a flaw in the CPU speculative branch
instruction execution feature. By conducting targeted cache side-channel
attacks and via a terminal page fault, an attacker could exploit this
vulnerability to leak information residing in the L1 data cache and read data
belonging to different security contexts. Note: This vulnerability is also
known as the "L1 Terminal Fault (L1TF)" or "Foreshadow" attack.
CVSS Base Score: 7.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
148318 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N)

CVEID: CVE-2017-15265
DESCRIPTION: Linux Kernel could allow a local attacker to gain elevated
privileges on the system, caused by a use-after-free memory error in the ALSA
sequencer interface (/dev/snd/seq). By persuading a victim to open a
specially-crafted application, an attacker could exploit this vulnerability to
execute arbitrary code on the system with elevated privileges.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
133342 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID: CVE-2017-0861
DESCRIPTION: Google Android could allow a remote attacker to gain elevated
privileges on the system, caused by a flaw in the Upstream kernel audio
driver. By persuading a victim to open a specially-crafted application, an
attacker could exploit this vulnerability to gain elevated privileges on the
system.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
135049 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID: CVE-2018-14634
DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain
elevated privileges on the system, caused by an integer overflow in the
create_elf_tables function. By using a specially-crafted binary file, an
attacker could exploit this vulnerability to obtain full root privileges.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
150310 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2018-5391
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by the
improper handling of the reassembly of fragmented IPv4 and IPv6 packets by the
IP implementation. By sending specially crafted IP fragments with random
offsets, a remote attacker could exploit this vulnerability to exhaust all
available CPU resources and cause a denial of service.
