Security Advisory

1) Buffer overflow

Risk: Low

CVSSv3: 3.8 [CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-3989

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in Cortado ThinPrint component. A remote authenticated attacker can trigger memory corruption and cause a denial of service condition on the target system.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

VMware Horizon Client: 5.0.0, 5.1.0, 5.2.0, 5.3, 5.4, 5.4.1, 5.4.2, 5.4.3

VMware Workstation: 15.0.0, 15.0.1, 15.0.2, 15.0.3, 15.0.4, 15.1.0, 15.5.0, 15.5.1, 15.5.2, 15.5.5, 15.5.6

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.

Is there known malware, which exploits this vulnerability?

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

2) Integer overflow

Risk: Low

CVSSv3: 3.8 [CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-3990

CWE-ID: CWE-190 - Integer Overflow or Wraparound

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information on the system.

The vulnerability exists due to integer overflow in Cortado ThinPrint component. A remote authenticated attacker can pass specially crafted data to the application, trigger integer overflow and gain access to sensitive information on the target system.

Mitigation

Install updates from vendor's website.

3) Out-of-bounds read

Risk: Medium

CVSSv3: 4.7 [CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C] [PCI]

CVE-ID: CVE-2020-3988

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in the Cortado ThinPrint component in JPEG2000 parser. A remote authenticated attacker can use a specially crafted EMF file, trigger out-of-bounds read error and read contents of memory on the system or cause a denial of service (DoS) condition.

Mitigation

Install updates from vendor's website.
