| Package | Affected versions | Patched versions |
|---|---|---|
| freerdp | ≥ 3.29.0, < 3.32.0 | 3.32.0 |
FreeRDP 3.29.0 before 3.32.0 contains a double free in the client's async-update message proxy, which shallow-copies the parser-owned PolygonSC or PolygonCB points array when numPoints is zero, so both the queue consumer and parser cleanup free it. A malicious RDP server can send a point-bearing polygon order followed by a zero-point order to crash a client with +async-update enabled.
