The problem can be corrected by upgrading your system to the following package versions: Ubuntu 8.04 LTS: vinagre 0.5.1-0ubuntu1.1 Ubuntu 8.10: vinagre 2.24.1-0ubuntu1.1 After a standard system upgrade you need to restart Vinagre to effect the necessary changes. Details follow: Alfredo Ortega discovered a flaw in Vinagre's use of format strings. A remote attacker could exploit this vulnerability if they tricked a user into connecting to a malicious VNC server, or opening a specially crafted URI with Vinagre. In Ubuntu 8.04, it was possible to execute arbitrary code with user privileges. In Ubuntu 8.10, Vinagre would simply abort, leading to a denial of service.
