Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Information disclosure
EUVDB-ID: #VU9882
Risk: Low
CVSSv3.1: 5 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-5754
CWE-ID:
CWE-200 - Information exposure
Exploit availability: Yes
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists in Intel CPU hardware due to side-channel attacks, which are also referred to as Meltdown attacks. A local attacker can execute arbitrary code, perform a side-channel analysis of the data cache and gain access to sensitive information including memory from the CPU cache.
MitigationInstall updates from vendor's website.

Q & 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.
How the attacker can exploit this vulnerability?
The attacker would have to trick the victim to open a a specially crafted file.
The attacker would have to login to the system and perform certain actions in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) Speculative Store Bypass
EUVDB-ID: #VU12911
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-2018-3639
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 execution of Load and Store instructions to read privileged memory.
Note: the vulnerability is referred to as "Spectre variant 4".
