FreeRDP before 3.32.2 Client Denial of Service via Zero-Output ZGFX Payload

Özet

Türkçe özeti yalnızca kritik ve yüksek önemdeki açıklar için hazırlıyoruz. Bu açık için kaynağın kendi açıklamasını gösteriyoruz.

FreeRDP before 3.32.2 allows a client assertion abort because rdpgfx_on_data_received rejects only negative zgfx_decompress status and passes the resulting null output pointer to Stream_StaticConstInit. A malicious RDP server can send a zero-output ZGFX payload on the RDPGFX channel after session activation to terminate the client.
