Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2020-0594)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in IPv6 subsystem. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system, leading to privilege escalation.
Note: This vulnerability affects the following versions of Intel AMT and ISM:
- 11.0 through 11.8.76
- 11.10 through 11.11.76
- 11.20 through 11.22.76
- 12.0 through 12.0.63
2) Use-after-free (CVE-ID: CVE-2020-0595)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in IPv6 subsystem. A remote attacker can gain elevated privileges on the target system.
Note: This vulnerability affects the following versions of Intel AMT and ISM:
- 11.0 through 11.8.76
- 11.10 through 11.11.76
- 11.20 through 11.22.76
- 12.0 through 12.0.63
3) Input validation error (CVE-ID: CVE-2020-0538)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in subsystem. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
Note: This vulnerability affects the following versions of Intel AMT:
- 11.0 through 11.8.76
- 11.10 through 11.11.76
- 11.20 through 11.22.76
- 12.0 through 12.0.63
4) Information disclosure (CVE-ID: CVE-2020-0596)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to improper input validation in DHCPv6 subsystem. A remote attacker can gain unauthorized access to sensitive information on the system.
Note: This vulnerability affects the following versions of Intel AMT and ISM:
- 11.0 through 11.8.76
- 11.10 through 11.11.76
- 11.20 through 11.22.76
- 12.0 through 12.0.63
5) Input validation error (CVE-ID: CVE-2020-0532)
The vulnerability allows a local attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in subsystem. An attacker with physical access can pass specially crafted input to the application and perform a denial of service (DoS) attack or disclose sensitive information on the target system.
Note: This vulnerability affects the following versions of Intel AMT:
- 11.0 through 11.8.76
- 11.10 through 11.11.76
- 11.20 through 11.22.76
- 12.0 through 12.0.63
6) Information disclosure (CVE-ID: CVE-2020-0531)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to improper input validation. A remote authenticated attacker can gain unauthorized access to sensitive information on the system.
Note: This vulnerability affects the following versions of Intel AMT:
- 11.0 through 11.8.76
- 11.10 through 11.11.76
- 11.20 through 11.22.76
- 12.0 through 12.0.63
7) Insufficiently protected credentials (CVE-ID: CVE-2020-0540)
The vulnerability allows a remote attacker to gain access to sensitive information on the system.
The vulnerability exists due to insufficiently protected credentials. A remote attacker can gain unauthorized access to sensitive information on the target system.
Note: This vulnerability affects the following versions of Intel AMT:
- 11.0 through 11.8.76
- 11.10 through 11.11.76
- 11.20 through 11.22.76
- 12.0 through 12.0.63
8) Input validation error (CVE-ID: CVE-2020-0537)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in subsystem. A remote authenticated attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
Note: This vulnerability affects the following versions of Intel AMT:
- 11.0 through 11.8.76
- 11.10 through 11.11.76
- 11.20 through 11.22.76
- 12.0 through 12.0.63
