## Overview

A flaw was found in the FreeRDP used by Anaconda's remote install feature, where a crafted RDP packet could trigger a segmentation fault. This issue causes the service to crash and remain defunct, resulting in a denial of service. It occurs pre-boot and is likely due to a NULL pointer dereference. Rebooting is required to recover the system.

## Affected

- `freerdp >= 3.0.0, < 3.16.0`
- `enterprise_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `freerdp 3.16.0`
