AI-suggested
The vulnerability is fixed in FreeRDP version 3.32.2 and later. Users should update their FreeRDP packages to the patched versions provided by their Linux distribution, such as those listed in the Ubuntu security notice USN-9007-1. Standard system updates will apply the necessary fixes. No additional mitigation is required once the update is applied.
Description
FreeRDP versions from 3.0.0 before 3.32.2 contain a file descriptor leak in the function parallel_process_irp_create. This leak occurs because previous descriptors are not closed on repeated IRP_MJ_CREATE requests. A hostile RDP server with parallel-device redirection enabled can exploit this by sending repeated CREATE requests to exhaust the client's descriptor table, causing the FreeRDP process to crash.
