Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Race condition (CVE-ID: CVE-2024-23599)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a race condition in Seamless Firmware Updates for some Intel reference platforms. A local user can exploit the race and perform a denial of service (DoS) attack.
2) Input validation error (CVE-ID: CVE-2024-21871)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to insufficient validation of user-supplied input within the UEFI firmware. A local privileged user can execute arbitrary code with elevated privileges.
3) Improper access control (CVE-ID: CVE-2023-43626)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper access restrictions within the UEFI firmware. A local privileged user can execute arbitrary code with elevated privileges.
4) Untrusted pointer dereference (CVE-ID: CVE-2023-42772)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to untrusted pointer dereference in UEFI firmware. A local privileged user can execute arbitrary code with elevated privileges.
5) Input validation error (CVE-ID: CVE-2024-21829)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to insufficient input validation in UEFI firmware error handler. A local privileged user can execute arbitrary code with elevated privileges.
6) Input validation error (CVE-ID: CVE-2024-21781)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation in UEFI firmware. A local privileged user can gain access to sensitive information or perform a denial of service (DoS) attack.
7) Race condition (CVE-ID: CVE-2023-41833)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in UEFI firmware. A local privileged user can exploit the race and escalate privileges on the system.
8) NULL pointer dereference (CVE-ID: CVE-2023-23904)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a NULL pointer dereference error in the UEFI firmware. A local privileged user can escalate privileges on the system.
9) Out-of-bounds write (CVE-ID: CVE-2023-22351)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in the UEFI firmware. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
10) Improper handling of exceptional conditions (CVE-ID: CVE-2023-43753)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to improper handling of errors in Intel Processors with Intel Software Guard Extensions. A local user can gain access to sensitive information.
11) Out-of-bounds read (CVE-ID: CVE-2023-25546)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition in the UEFI firmware. A local user can trigger an out-of-bounds read error and perform a denial of service attack.
