Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Side-channel attack
EUVDB-ID: #VU14410
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-3615
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists due to an error in systems with microprocessors utilizing speculative execution and Intel® software guard extensions (Intel® SGX). A local attacker can conduct side-channel attack and gain access to potentially sensitive information residing in the L1 data cache from an enclave.
Install update from vendor's website.
Vulnerable software versionsCloudBoost Virtual Appliance: before 18.2.0.1
CPE2.3Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Side-channel attack
EUVDB-ID: #VU14411
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-3620
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists due to an error in systems with microprocessors utilizing speculative execution and address translations . A local attacker can trigger terminal page fault, conduct side-channel attack and gain access to potentially sensitive information residing in the L1 data cache.

3) Rogue System Register Read
EUVDB-ID: #VU12914
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-3640
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists due to race conditions in CPU cache processing. A local attacker can conduct a side-channel attack to exploit a flaw in the speculative loading of system registers to read privileged system registers
Note: the vulnerability is referred to as "Spectre variant 3A".

4) Side-channel attack
EUVDB-ID: #VU14412
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-3646
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows an adjacent attacker to obtain potentially sensitive information.
The vulnerability exists due to an error in systems with microprocessors utilizing speculative execution and address translations. An adjacent attacker with guest OS privilege can trigger terminal page fault, conduct side-channel attack and gain access to potentially sensitive information residing in the L1 data cache.
