Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Race condition (CVE-ID: CVE-2020-8670)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the firmware . A local administrator can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
2) Buffer overflow (CVE-ID: CVE-2020-8703)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in a subsystem. A local administrator can trigger memory corruption and gain elevated privileges on the target system.
3) Race condition (CVE-ID: CVE-2020-8704)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in subsystem. A local administrator can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
4) Improper Initialization (CVE-ID: CVE-2020-12357)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper initialization in the firmware. A local administrator can run a specially crafted application to execute arbitrary code with escalated privileges on the system.
5) Buffer overflow (CVE-ID: CVE-2020-12358)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when in the firmware. A local administrator can trigger memory corruption and cause a denial of service condition on the target system.
6) Out-of-bounds read (CVE-ID: CVE-2020-12360)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the firmware. A local user can trigger out-of-bounds read error and read contents of memory on the system.
7) Input validation error (CVE-ID: CVE-2020-24486)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in the firmware. A local user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
8) Out-of-bounds read (CVE-ID: CVE-2020-24506)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in a subsystem. A local administrator can trigger out-of-bounds read error and read contents of memory on the system.
9) Information disclosure (CVE-ID: CVE-2020-24507)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to improper initialization in a subsystem. A local administrator can gain unauthorized access to sensitive information on the system.
10) Information disclosure (CVE-ID: CVE-2020-24511)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to improper isolation of shared resources. A local user can gain unauthorized access to sensitive information on the system.
11) Observable discrepancy (CVE-ID: CVE-2020-24512)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to observable timing discrepancy. A local user can gain unauthorized access to sensitive information on the system.
12) Information disclosure (CVE-ID: CVE-2020-24513)
The vulnerability allows a local user o gain access to potentially sensitive information.
The vulnerability exists due to domain-bypass transient execution issue. A local user can gain unauthorized access to sensitive information on the system.
