Ubuntu 8.04 LTS / 8.10 : vinagre vulnerability (USN-689-1)

Ubuntu Security Notice (C) 2008-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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.

Solution :

Update the affected vinagre package.

Risk factor :
