Updated 06.12.2019
Added vulnerability #2

1) Out-of-bounds write

EUVDB-ID: #VU21156

Risk: High

CVSSv3.1: 7.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2019-5049

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker with access to guest operation system can pass a specially crafted pixel shader file to the AMD ATIDXX64.DLL driver for Radeon RX 550 / 550 Series, trigger out-of-bounds write and execute arbitrary code on the host operating system.

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

Mitigation

Install updates from vendor's website.

2) Out-of-bounds read

EUVDB-ID: #VU23430

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-5098

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

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 condition when processing untrusted input. A remote attacker with access to guest operation system can pass a specially crafted pixel shader file to the AMD ATIDXX64.DLL driver for Radeon RX 550 / 550 Series, trigger out-of-bounds read error and cause a denial of service condition on the target system.
