"Updated firefox packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 5, 6, and 7.

Red Hat Product Security has rated this update as having Critical
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

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-2015-4513, CVE-2015-7189, CVE-2015-7194,
CVE-2015-7196, CVE-2015-7198, CVE-2015-7197)

A same-origin policy bypass flaw was found in the way Firefox handled
certain cross-origin resource sharing (CORS) requests. A web page
containing malicious content could cause Firefox to disclose sensitive
information. (CVE-2015-7193)

A same-origin policy bypass flaw was found in the way Firefox handled
URLs containing IP addresses with white-space characters. This could
lead to cross-site scripting attacks. (CVE-2015-7188)

Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Christian Holler, David Major, Jesse
Ruderman, Tyson Smith, Boris Zbarsky, Randell Jesup, Olli Pettay, Karl
Tomlinson, Jeff Walden, and Gary Kwong, Michal Bentkowski, Looben
Yang, Shinto K Anto, Gustavo Grieco, Vytautas Staraitis, Ronald Crane,
and Ehsan Akhgari as the original reporters of these issues.

All Firefox users should upgrade to these updated packages, which
contain Firefox version 38.4.0 ESR, which corrects these issues. After
installing the update, Firefox must be restarted for the changes to
take effect."
