Name of the Vulnerable Software and Affected Versions FreeRDP version 3.32.0

Description A use-after-free issue exists in the drdynvc channel. This occurs when a pool-owned stream is freed using the owned-stream deallocator because the totalLength is smaller than the chunk size. A malicious RDP server can trigger this by sending a single well-formed Virtual Channel PDU, leading to a client crash during teardown.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
