Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU22712

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2018-12207

CWE-ID: CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

Exploit availability: No

Description

The vulnerability allows a local user to perform denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the mechanism responsible for error handling on some Intel platforms. A local user of a guest operating system can use a specially crafted application to trigger memory corruption and cause the host system to stop responding.

Successful exploitation of this vulnerability may result in a denial of service (DoS) attack.

Below is the list of processor families that are affected by this vulnerability:

Client:

  • Intel Core i3 Processors
  • Intel Core i5 Processors
  • Intel Core i7 Processors
  • Intel Core m Processor Family
  • 2nd generation Intel Core Processors
  • 3rd generation Intel Core Processors
  • 4th generation Intel Core Processors
  • 5th generation Intel Core Processors
  • 6th generation Intel Core Processors
  • 7th generation Intel Core Processors
  • 8th generation Intel Core Processors
  • Intel Core X-series Processor Family
  • Intel Pentium Gold Processor Series
  • Intel Celeron Processor G Series

Server:

  • 2nd Generation Intel Xeon Scalable Processors

2) Resource management error

EUVDB-ID: #VU22704

Risk: Low

CVSSv3.1:

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

Install updates from vendor's website.
