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.

The remote Ubuntu 24.04 LTS / 25.04 host has packages installed that are affected by a vulnerability as referenced in the USN-7624-1 advisory.

    It was discovered that FreeRDP incorrectly handled certain RDP packets. A remote attacker could possibly     use this issue to cause FreeRDP to crash, resulting in a denial of service.
