Synopsis:	Moderate: vnc security update
Issue date:	2009-02-11
CVE Names:	CVE-2008-4770

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.
