Description

The remote host is missing updates announced in advisory RHSA-2009:0261.

Virtual Network Computing (VNC) is a remote display system which allows you to view a computer's desktop environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures.

An insufficient input validation flaw was discovered in the VNC client application, vncviewer. If an attacker could convince a victim to connect to a malicious VNC server, or when an attacker was able to connect to vncviewer running in the listen mode, the attacker could cause the victim's vncviewer to crash or, possibly, execute arbitrary code. (CVE-2008-4770)

Users of vncviewer should upgrade to these updated packages, which contain a backported patch to resolve this issue. For the update to take effect, all running instances of vncviewer must be restarted after the update is installed.
