Security Bulletin

This security bulletin contains information about 3 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

Description

The 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.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

Red Hat Enterprise Linux Server - AUS: 6.2

kernel (Red Hat package): 2.6.32-71.7.1.el6 - 2.6.32-220.76.1.el6

CPE2.3 External links

http://access.redhat.com/errata/RHSA-2018:0020


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.

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) Information disclosure

EUVDB-ID: #VU9884

Risk: Low

CVSSv3.1: 5.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2017-5753

CWE-ID: CWE-200 - Information exposure

Exploit availability: Yes

Description

The vulnerability allows a local attacker to obtain potentially sensitive information.

The vulnerability exists in Intel CPU hardware due to improper implementation of the speculative execution of instructions. A local attacker can perform a bounds check bypass, execute arbitrary code, conduct a side-channel attack and read sensitive memory information.

Mitigation

Install updates from vendor's website.

CVE-ID: CVE-2017-5715

CWE-ID: CWE-200 - Information exposure

Exploit availability: Yes

Description

The vulnerability allows a local attacker to obtain potentially sensitive information.

The vulnerability exists in Intel CPU hardware due to improper implementation of the speculative execution of instructions. A local attacker can utilize branch target injection, execute arbitrary code, perform a side-channel attack and read sensitive memory information.

Mitigation

Install updates from vendor's website.
