GLSA-202411-01 : Neat VNC: Authentication Bypass

high Nessus Plugin ID 210396

Language:

Description

The remote host is affected by the vulnerability described in GLSA-202411-01 (Neat VNC: Authentication Bypass)

 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.

Tenable has extracted the preceding description block directly from the Gentoo Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

All Neat VNC users should upgrade to the latest version:

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