Description:
Some vulnerabilities have been discovered in WinRemotePC, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.

1) An input validation error in the WinRemotePC Server service (WRPCServer.exe) can be exploited to cause a heap-based buffer overflow via an overly long, specially crafted packet sent to default port 4321/TCP.

Successful exploitation may allow execution of arbitrary code.

2) An input validation error in the WinRemotePC Server service can be exploited to cause the service to consume large amounts of CPU resources via a specially crafted packet sent to default port 4321/TCP.

3) An input validation error in the WinRemotePC Server service can be exploited to cause the service to consume large amounts of memory resources via a specially crafted packet sent to default port 4321/TCP.

The vulnerabilities are confirmed in WinRemotePC Lite 2008 and also reported in WinRemotePC Full 2008. Other versions may also be affected.
