critical Nessus Plugin ID 60535

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)

For the update to take effect, all running instances of vncviewer must be restarted after the update is installed.

Solution

Update the affected vnc and / or vnc-server packages.
