Exploitation Summary

AI-analyzed exploit summary This exploit demonstrates a persistent denial of service (DoS) vulnerability in Vino VNC Server by sending malformed data during the authentication stage, causing the service to enter an infinite loop and become unresponsive.

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.
