- Metasploit Modules Related To CVE-2008-0610

UltraVNC 1.0.2 Client (vncviewer.exe) Buffer Overflow
This module exploits a buffer overflow in UltraVNC Viewer 1.0.2 Release. If a malicious server responds to a client connection indicating a minor protocol version of 14 or 16, a 32-bit integer is subsequently read from the TCP stream by the client and directly provided as the trusted size for further reading from the TCP stream into a 1024-byte character array on the stack.
