Scientific Linux Security Update : vnc on SL3.x, SL4.x, SL5.x i386/x86_64

Critical Nessus Plugin ID 60535


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


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.


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