Description

This security bulletin contains information about 17 secuirty vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2023-38575)

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to non-transparent sharing of return predictor targets between contexts in some Intel Processors. A local user can gain unauthorized access to sensitive information on the system.


2) Information disclosure (CVE-ID: CVE-2024-22255)

The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to excessive data output in the UHCI USB controller. A remote user with administrative access to the guest OS can read memory from the vmx process.


3) Out-of-bounds write (CVE-ID: CVE-2024-22254)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error when processing untrusted input. A local user with privileges within the VMX process can trigger an out-of-bounds write and escape sandbox restrictions.


4) Use-after-free (CVE-ID: CVE-2024-22253)

The vulnerability allows a remote user to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in the UHCI USB controller. A remote attacker with administrative access to the guest OS can trigger a use-after-free error and execute arbitrary code on the host OS.

On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.


5) Use-after-free (CVE-ID: CVE-2024-22252)

The vulnerability allows a remote user to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in the XHCI USB controller. A remote attacker with administrative access to the guest OS can trigger a use-after-free error and execute arbitrary code on the host OS.

On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed.


6) Improper access control (CVE-ID: CVE-2024-21828)

The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions. A local user can bypass implemented security restrictions and gain unauthorized access to the application.


7) Resource exhaustion (CVE-ID: CVE-2023-35191)

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to firmware does not properly control consumption of internal resources. A remote user can trigger resource exhaustion and perform a denial of service (DoS) attack.


8) Security features bypass (CVE-ID: CVE-2023-22655)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a protection mechanism failure in some 3rd and 4th Generation Intel Xeon Processors when using Intel SGX or Intel TDX. A local user can execute arbitrary code with elevated privileges.


9) Protection Mechanism Failure (CVE-ID: CVE-2023-39368)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient implementation of security measures in the bus lock regulator mechanism. A remote attacker can trick the victim to open a specially crafted file and perform a denial of service (DoS) attack.


10) Improper access control (CVE-ID: CVE-2023-32666)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper access restrictions within the on-chip debug and test interface when using Intel SGX or Intel TDX. A local privileged user can bypass implemented security restrictions and escalate privileges on the system.


11) Input validation error (CVE-ID: CVE-2024-0161)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper SMM communication buffer verification vulnerability. A local user can pass specially crafted input to the application and perform a denial of service (DoS) attack.


12) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-31347)

The vulnerability allows a local user to modify data on other guests.

The vulnerability exists due to improper privilege management in Secure_TSC, SEV firmware. A local user can cause a guest to observe an incorrect TSC when Secure TSC is enabled potentially resulting in a loss of guest integrity.


13) Improper Initialization (CVE-ID: CVE-2023-31346)

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to improper initialization in SEV Firmware. A local user can run a specially crafted application to access stale data from other guests.


14) Access of Memory Location After End of Buffer (CVE-ID: CVE-2024-0173)

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to improper parameter initialization. A local low privileged attacker could potentially exploit this vulnerability to read the contents of non-SMM stack memory.


15) Access of Memory Location After End of Buffer (CVE-ID: CVE-2024-0154)

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to improper parameter initialization. A local low privileged attacker could potentially exploit this vulnerability to read the contents of non-SMM stack memory.


16) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2024-0163)

The vulnerability allows a local user to gain access to gain access to otherwise unauthorized resources.

The vulnerability exists due to TOCTOU race condition. A local low privileged attacker could potentially exploit this vulnerability to gain access to otherwise unauthorized resources.


17) Buffer overflow (CVE-ID: CVE-2024-0162)

The vulnerability allows a local user to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error. A local low privileged attacker could potentially exploit this vulnerability leading to out-of-bound read/writes to SMRAM.
