Neat VNC: Authentication Bypass

Neat VNC: Authentication Bypass A vulnerability has been discovered in Neat VNC, which can lead to authentication bypass. neatvnc 2024-11-06 2024-11-06 937140 remote 0.8.1 0.8.1

Neat VNC is a liberally licensed VNC server library that's intended to be fast and neat.

Neat VNC allows remote attackers to bypass authentication via a request in which the client specifies an insecure security type such as "Type 1 - None", which is accepted even if it is not offered by the server, as originally demonstrated using a long password.

A remote attacker can opt not to use any authentication method and access the VNC server.

There is no known workaround at this time.

All Neat VNC users should upgrade to the latest version:


          # emerge --sync
          # emerge --ask --oneshot --verbose ">=gui-libs/neatvnc-0.8.1"
