| Doc Text: |
A flaw was found in FreeRDP. FreeRDP clients using TS Gateway are vulnerable to a heap-buffer-overflow. A malicious gateway can send a specially crafted response fragment, causing the client to write beyond its allocated buffer. This can lead to a client crash, resulting in a Denial of Service (DoS), and may also allow an attacker to execute arbitrary code on the client system.
