<title>LibVNCServer: Authentication bypass</title>
|
|
<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.

LibVNCServer is a GPL'ed library for creating VNC servers.

<description>
|
|
<p>
|
|
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 type="high">
|
|
<p>
|
|
An attacker could use this vulnerability to gain unauthorized access
|
|
with the privileges of the user running the VNC server.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All LibVNCServer users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-libs/libvncserver-0.8.2"</code>
