Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Improper isolation or compartmentalization

EUVDB-ID: #VU60450

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-0060

CWE-ID: CWE-653 - Improper isolation or compartmentalization

Exploit availability: No

Description

The vulnerability allows a local attacker to escalate privileges on the system.

The vulnerability exists due to insufficient compartmentalization in HECI subsystem for the Intel(R) SPS. An attacker with physical access to the system can execute arbitrary code with elevated privileges.

Mitigation

Install update from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

No. The attacker should have physical access to the system in order to successfully exploit this vulnerability.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Improper access control

EUVDB-ID: #VU60610

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-0092

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions in the firmware. A local administrator can bypass implemented security restrictions and perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.

3) Information disclosure

EUVDB-ID: #VU64364

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-21123

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows an attacker to gain access to potentially sensitive information.

The vulnerability exists in Intel processors due to excessive data output when DirectPath I/O (PCI-Passthrough) is utilized. An attacker (both local and remote) with administrative access to a virtual machine that has an attached DirectPath I/O (PCI-Passthrough) device can obtain information stored in physical memory about the hypervisor or other virtual machines that reside on the same host.


Mitigation

Install update from vendor's website.
