Synopsis

The remote Red Hat host is missing a security update for novnc.

Description

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2015:0884 advisory.

The novnc package provides a VNC client that uses HTML5 (Web Sockets, Canvas) and includes encryption support.

It was discovered that noVNC did not properly set the 'secure' flag when issuing cookies. An attacker could use this flaw to intercept cookies via a man-in-the-middle attack. (CVE-2013-7436)

All novnc users are advised to upgrade to this updated package, which corrects this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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

Update the RHEL novnc package based on the guidance in RHSA-2015:0884.
