Synopsis

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

Description

The remote Redhat Enterprise Linux 6 / 7 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2017:3382 advisory.

Mozilla Firefox is an open source web browser.

This update upgrades Firefox to version 52.5.1 ESR.

Security Fix(es):

* A privacy flaw was discovered in Firefox. In Private Browsing mode, a web worker could write persistent data to IndexedDB, which was not cleared when exiting and would persist across multiple sessions. A malicious website could exploit the flaw to bypass private-browsing protections and uniquely fingerprint visitors. (CVE-2017-7843)

Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges Konark as the original reporter.

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.
