+ <synopsis>
+ LTSP includes a version of libVNCServer that is vulnerable to an
+ authentication bypass.

+ The Linux Terminal Server Project adds thin-client support to Linux

+ <description>
+ <p>
+ The LTSP server includes vulnerable LibVNCServer code, which fails to
+ properly validate protocol types effectively letting users decide what
+ protocol to use, such as "Type 1 - None" (GLSA-200608-05). The LTSP VNC
+ server will accept this security type, even if it is not offered by the
+ server.
+ </p>
+ </description>
+ <impact type="high">
+ <p>
+ An attacker could exploit 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 LTSP users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-misc/ltsp-4.2-r1"</code>
+ </resolution>
