Description

This security bulletin contains information about 11 secuirty vulnerabilities.


1) Incorrect permission assignment for critical resource (CVE-ID: CVE-2020-17402)

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

The vulnerability exists due to an error within the prl_hypervisor kext. A local user can view contents of a log file and gain access to sensitive information.


2) Out-of-bounds read (CVE-ID: CVE-2020-17401)

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

The vulnerability exists due to a boundary condition within the VGA virtual device. A local user can run a specially crafted program to trigger out-of-bounds read error and read contents of memory on the system.


3) Out-of-bounds read (CVE-ID: CVE-2020-17400)

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to a boundary condition within the prl_hypervisor kext. A local user to run a specially crafted program to trigger out-of-bounds read error and execute arbitrary code in the context of the hypervisor.


4) Out-of-bounds write (CVE-ID: CVE-2020-17399)

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

The vulnerability exists due to a boundary error when processing untrusted input within the prl_hypervisor kext. A local user can run a specially crafted program to trigger out-of-bounds write and execute arbitrary code in the context of the kernel.


5) Out-of-bounds read (CVE-ID: CVE-2020-17398)

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

The vulnerability exists due to a boundary condition within the prl_hypervisor kext. A local user can run a specially crafted program to trigger out-of-bounds read error and read contents of memory on the system.


6) Out-of-bounds read (CVE-ID: CVE-2020-17397)

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

The vulnerability exists due to a boundary condition within the handling of network packets. A local user can run a specially crafted application to trigger out-of-bounds read error and  in the context of the hypervisor.


7) Integer overflow (CVE-ID: CVE-2020-17396)

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

The vulnerability exists due to integer overflow within the prl_hypervisor module. A local user can run a specially crafted program to trigger integer overflow and execute arbitrary code in the context of the kernel.


8) Integer underflow (CVE-ID: CVE-2020-17395)

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

The vulnerability exists due to integer underflow within the prl_naptd process. A local user can run a specially crafted program to trigger integer underflow and execute arbitrary code  in the context of the hypervisor.


9) Out-of-bounds read (CVE-ID: CVE-2020-17394)

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

The vulnerability exists due to a boundary condition within the OEMNet component. A local user can run a specially crafted program to trigger out-of-bounds read error and read contents of memory on the system.


10) Untrusted Pointer Dereference (CVE-ID: CVE-2020-17392)

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

The vulnerability exists due to untrusted pointer dereference error when handling HOST_IOCTL_SET_KERNEL_SYMBOLS in the prl_hypervisor kext. A local user to can run a specially crafted program to trigger pointer dereference and execute arbitrary code on the system in the context of the kernel.


11) Information disclosure (CVE-ID: CVE-2020-17391)

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

The vulnerability exists due to an error in handling the HOST_IOCTL_INIT_HYPERVISOR in the prl_hypervisor kext. A local user can gain unauthorized access to sensitive information on the system.
