WinVNC 3.3.3 and earlier generates the same challenge string for multiple connections, which allows remote attackers to bypass VNC authentication by sniffing the challenge and response of other users.
WinVNC installs the WinVNC3 registry key with permissions that give Special Access (read and modify) to the Everybody group, which allows users to read and modify sensitive information such as passwords and gain access to the system.
Buffer overflow in AT&T WinVNC (Virtual Network Computing) server 3.3.3r7 and earlier allows remote attackers to execute arbitrary commands via a long HTTP GET request when the DebugLevel registry key is greater than 0.
Buffer overflow in AT&T WinVNC (Virtual Network Computing) client 3.3.3r7 and earlier allows remote attackers to execute arbitrary commands via a long rfbConnFailed packet with a long reason string.
