Synopsis ========
VNC servers created with LibVNCServer accept insecure protocol types, even when the server does not offer it, resulting in unauthorized access to the server.
Background ==========
LibVNCServer is a GPL'ed library for creating VNC servers.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-libs/libvncserver < 0.8.2 >= 0.8.2
Description ===========
LibVNCServer fails to properly validate protocol types effectively letting users decide what protocol to use, such as "Type 1 - None". LibVNCServer will accept this security type, even if it is not offered by the server.
Impact ======
An attacker could use this vulnerability to gain unauthorized access with the privileges of the user running the VNC server.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All LibVNCServer users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-libs/libvncserver-0.8.2"
References ==========
