VNC: GNOME Vino VNC Server Denial of Service

This signature detects attempts to exploit a known vulnerability against GNOME Vino VNC Server. A successful attack can result in a denial-of-service condition.

Extended Description

The vino_server_client_data_pending function in vino-server.c in GNOME Vino 2.26.1, 2.32.1, 3.7.3, and earlier, and 3.8 when encryption is disabled, does not properly clear client data when an error causes the connection to close during authentication, which allows remote attackers to cause a denial of service (infinite loop, CPU and disk consumption) via multiple crafted requests during authentication.
