Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Unchecked Return Value (CVE-ID: CVE-2021-0107)
The vulnerability allows a local administrator to escalate privileges on the system.
The vulnerability exists due to unchecked return value in the firmware, which leads to security restrictions bypass and privilege escalation.
2) Incorrect default permissions (CVE-ID: CVE-2021-0093)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect default permissions in the firmware. A local administrator can cause a denial of service condition on the target system.
3) Improper access control (CVE-ID: CVE-2021-0091)
The vulnerability allows a local attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in the firmware. A local attacker can bypass implemented security restrictions and gain elevated privileges on the system.
4) Improper access control (CVE-ID: CVE-2021-0092)
The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in the firmware. A local administrator can bypass implemented security restrictions and perform a denial of service (DoS) attack.
5) Improper Initialization (CVE-ID: CVE-2021-0119)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper initialization in the firmware. An administrator with physical access can gain elevated privileges on the target system.
6) Improper access control (CVE-ID: CVE-2021-0124)
The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in the firmware. A local administrator can bypass implemented security restrictions and gain elevated privileges on the system.
7) Improper Initialization (CVE-ID: CVE-2021-0125)
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.
8) NULL pointer dereference (CVE-ID: CVE-2021-0111)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a NULL pointer dereference error in the firmware. A local administrator can pass specially crafted data to the application and gain elevated privileges on the system.
9) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2021-0103)
The vulnerability allows a local administrator to escalate privileges on the system.
The vulnerability exists due to insufficient control flow management in the firmware, which leads to security restrictions bypass and privilege escalation.
10) Input validation error (CVE-ID: CVE-2021-0156)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to insufficient validation of user-supplied input in the firmware. A local administrator can pass specially crafted input to the application and gain elevated privileges on the system.
11) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2021-0099)
The vulnerability allows a local administrator to escalate privileges on the system.
The vulnerability exists due to insufficient control flow management in the firmware, which leads to security restrictions bypass and privilege escalation.
12) Out-of-bounds read (CVE-ID: CVE-2021-0118)
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 administrator can trigger out-of-bounds read error and read contents of memory on the system, leading to privilege escalation.
13) Access of Uninitialized Pointer (CVE-ID: CVE-2021-0117)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to pointer issues in the firmware. A local administrator can gain elevated privileges on the system.
14) Out-of-bounds write (CVE-ID: CVE-2021-0116)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error when processing untrusted input in the firmware. A local administrator can trigger out-of-bounds write and gain elevated privileges on the system.
15) Buffer overflow (CVE-ID: CVE-2021-0115)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in the firmware. A local administrator can trigger memory corruption and gain elevated privileges on the system.
16) Unchecked Return Value (CVE-ID: CVE-2021-0114)
The vulnerability allows a local administrator to escalate privileges on the system.
The vulnerability exists due to unchecked return value in the firmware, which leads to security restrictions bypass and privilege escalation.
