Description

This security bulletin contains information about 4 vulnerabilities.


1) Out-of-bounds write (CVE-ID: CVE-2020-6100)

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

CVSSv4: 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


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the Shader functionality "MOV REG". A remote authenticated attacker can use a specially crafted shader file, trigger out-of-bounds write and execute arbitrary code on the target system.


2) Out-of-bounds write (CVE-ID: CVE-2020-6103)

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

CVSSv4: 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


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the Shader functionality "ROUND_NI". A remote authenticated attacker can use a specially crafted shader file, trigger out-of-bounds write and execute arbitrary code on the target system.


3) Out-of-bounds write (CVE-ID: CVE-2020-6102)

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

CVSSv4: 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


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the Shader functionality "RESOURCE". A remote authenticated attacker can use a specially crafted shader file, trigger out-of-bounds write and execute arbitrary code on the target system.


4) Out-of-bounds write (CVE-ID: CVE-2020-6101)

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

CVSSv4: 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


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the Shader functionality "DCL_OUTPUT". A remote authenticated attacker can use a specially crafted shader file, trigger out-of-bounds write and execute arbitrary code on the target system.
