Name of the Vulnerable Software and Affected Versions FreeRDP versions 3.0.0 through 3.32.1

Description A file descriptor leak exists in the parallel process irp create() function. This occurs when the system fails to close previous descriptors during repeated IRP MJ CREATE requests. A malicious RDP server with parallel-device redirection enabled can exploit this by sending repeated CREATE requests to exhaust the client descriptor table, leading to a process crash.

Recommendations Update FreeRDP to version 3.32.2.
