Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) 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 the following updates:

ESXi 6.7 Patch Release ESXi670-201911001

ESXi 6.5 Patch Release ESXi650-201911001

ESXi 6.0 Patch Release ESXi600-201911001

VMware Workstation 15.5.1

VMware Fusion 11.5.1

Vulnerable software versions

VMware Fusion: 11.0.0 - 11.5.0

VMware Workstation: 15.0.0 - 15.5.0

VMware ESXi: 6.0 - 6.7

2) 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.
