Description OSIDB Bzimport 2026-11-05 21:59:47 UTC
FreeRDP before 3.32.2 contains a use-after-free vulnerability in the freerdp-proxy DRDYNVC tracker when intercepting the drdynvc channel. A malicious target server can repeatedly send CREATE_REQUEST_PDU for an active channel id, racing front DATA handling to free a borrowed context and crash the proxy process.
