CentOS Errata and Security Advisory CESA-2015:1586
Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.
Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox. (CVE-2015-4473, CVE-2015-4475, CVE-2015-4478, CVE-2015-4479,
