CVE-2017-2838 freerdp: Rdp Client License Read Product Info Denial of Service
An exploitable denial of service vulnerability exists within the handling of challenge packets in FreeRDP 2.0.0-beta1+android11. A specially crafted challenge packet can cause the program termination leading to a denial of service condition. An attacker can compromise the server or use man in the middle to trigger this vulnerability.
The vulnerability is located in the license read product info handling. A malicious crafted packet may cause the application to crash. The vulnerable code reads in an unsigned integer from the server message which then incremented by four as part of a length check. However, the size of the unsigned integer is never validated and thus the addition of four could cause an overflow and

[HIGH] Vulnerability Spotlight: FreeRDP Multiple Vulnerabilities
Vulnerabilities discovered by Tyler Bohan of Talos
## Overview
Talos has discovered multiple vulnerabilities in the FreeRDP product. FreeRDP is a free implementation of the Remote Desktop Protocol (RDP) originally developed by Microsoft. RDP allows users to connect remotely to systems so they can be operated from afar. The open source nature of the FreeRDP library means that it is integrated into many commercial remote desktop protocol applications.
We identified a number of vulnerabilities falling into 2 classes:
- 2 Code Executions;
- 4 Denials Of Service.
The first category allows code execution on the client side through a specially crafted response from a RDP server. The second category can cause the termination of the FreeRDP client. The vulnerabilities result from weaknesses in
