Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Improper access control

EUVDB-ID: #VU22781

Risk: Low

CVSSv3.1: 5.4 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2019-0117

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to improper access restrictions in protected memory subsystem for Intel(R) SGX for 6th, 7th, 8th, 9th Generation Intel(R) Core(TM) Processor Families; Intel(R) Xeon(R) Processor E3-1500 v5, v6 Families; Intel(R) Xeon(R) E-2100 & E-2200 Processor Families with Intel(R) Processor Graphics. A local user can gain access to sensitive information.

The following processor families are affected:

  • 6th Generation Intel Core processors
  • 7th Generation Intel Core processors
  • 8th Generation Intel Core processors
  • 9th Generation Intel Core processors
  • Intel Xeon Processor E3 v5 Family
  • Intel Xeon Processor E3 v6 Family
  • Intel Xeon Processor E- 2100 Family
  • Intel Xeon Processor E-2200 Family

Mitigation

Update the affected package intel-ucode to version 20191112-1.

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) Resource management error

EUVDB-ID: #VU22704

Risk: Low

CVSSv3.1: 5.1 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2019-11135

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the TSX Asynchronous Abort (TAA) in Intel CPUs. The TAA condition, on some microprocessors utilizing speculative execution, may allow an authenticated user to potentially enable information disclosure via a side channel.

Mitigation

Update the affected package intel-ucode to version 20191112-1.
