CentOS Errata and Security Advisory CESA-2015:1581
Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.
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)
Red Hat would like to thank the Mozilla project for reporting this issue.
Upstream acknowledges Cody Crews as the original reporter.
All Firefox users should upgrade to these updated packages, which contain
Firefox version 38.1.1 ESR, which corrects this issue. After installing the
update, Firefox must be restarted for the changes to take effect.
