Vulnerability Scan Summary
x11vnc: Authentication bypass in included LibVNCServer code
Detailed Explanation for this Vulnerability Test
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.
A possible hacker could exploit this vulnerability to gain unauthorized
access with the rights 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"
Threat Level: High
