medium Nessus Plugin ID 85296

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

A flaw was discovered in Mozilla Firefox that could be used to violate the same-origin policy and inject web script into a non-privileged part of the built-in PDF file viewer (PDF.js). An attacker could create a malicious web page that, when viewed by a victim, could steal arbitrary files (including private SSH keys, the /etc/passwd file, and other potentially sensitive files) from the system running Firefox.
(CVE-2015-4495)

After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected firefox and / or firefox-debuginfo packages.
