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-2013-1682, CVE-2013-1684, CVE-2013-1685,
CVE-2013-1686, CVE-2013-1687, CVE-2013-1690)
It was found that Firefox allowed data to be sent in the body of
XMLHttpRequest (XHR) HEAD requests. In some cases this could allow
attackers to conduct Cross-Site Request Forgery (CSRF) attacks.
Timing differences in the way Firefox processed SVG image files could
allow an attacker to read data across domains, potentially leading to
information disclosure. (CVE-2013-1693)
Two flaws were found in the way Firefox implemented some of its
internal structures (called wrappers). An attacker could use these
flaws to bypass some restrictions placed on them. This could lead to
unexpected behavior or a potentially exploitable crash.
Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Gary Kwong, Jesse Ruderman, Andrew
McCreight, Abhishek Arya, Mariusz Mlynski, Nils, Johnathan Kuskos,

For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 17.0.7 ESR. You can find a link to the
Mozilla advisories in the References section of this erratum.
All Firefox users should upgrade to these updated packages, which
contain Firefox version 17.0.7 ESR, which corrects these issues. After
