| Doc Text: |
A flaw was found in FreeRDP. This vulnerability allows an authenticated remote client to cause a Denial of Service (DoS) by exhausting system memory on the proxy server. When intercepting Dynamic Virtual Channel (DVC) communications, the proxy does not enforce cumulative limits on reassembling fragmented messages. An attacker can exploit this by transmitting incomplete fragments with large declared message sizes, continuously consuming proxy heap memory and degrading service availability.
