Debian DLA-1946-1 : novnc security update

medium Nessus Plugin ID 129594

Language:

Synopsis

The remote Debian host is missing a security update.

Description

An XSS vulnerability was discovered in noVNC in which the remote VNC server could inject arbitrary HTML into the noVNC web page via the messages propagated to the status field, such as the VNC server name.

For Debian 8 'Jessie', this problem has been fixed in version 1:0.4+dfsg+1+20131010+gitf68af8af3d-4+deb8u1.

We recommend that you upgrade your novnc packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected novnc, and python-novnc packages.
