The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200608-12
(x11vnc: Authentication bypass in included LibVNCServer code)
x11vnc 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). x11vnc will accept
this security type, even if it is not offered by the server.
An attacker could exploit this vulnerability to gain unauthorized
access with the privileges of the user running the VNC server.
There is no known workaround at this time.

All x11vnc users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=x11-misc/x11vnc-0.8.1'

High / CVSS Base Score : 7.5
