Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

Updated 30.10.2019
Added vulnerability #3, changed severity.

1) Out-of-bounds read

EUVDB-ID: #VU18687

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-5522

CWE-ID: CWE-125 - Out-of-bounds read

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 vm3dmp driver, installed  with vmtools on Windows guest machines. A local non-privileged user of a Windows guest machine can use a specially crafted application to trigger out-of-bounds read and gain access to kernel memory on the same guest OS or perform denial of service attack against guest OS.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

VMware Tools: 10.0.0 - 10.3.5

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.

2) Use-after-free

EUVDB-ID: #VU18688

Risk: Medium

CVSSv4.0: 5.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2019-5525

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error in advanced Linux Sound Architecture (ALSA) backend. A local non-privileged user of a guest OS can use a specially crafted application to trigger use-after-free error and execute arbitrary code on the Linux host where Workstation is installed.

Successful exploitation of the vulnerability may allow an attacker to compromise Linux host operating system.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

VMware Workstation: 15.0.0 - 15.0.4
