Description

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-2013-0801, CVE-2013-1674, CVE-2013-1675, CVE-2013-1676, CVE-2013-1677, CVE-2013-1678, CVE-2013-1679, CVE-2013-1680, CVE-2013-1681)

A flaw was found in the way Firefox handled Content Level Constructors. A malicious site could use this flaw to perform cross-site scripting (XSS) attacks. (CVE-2013-1670)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Christoph Diehl, Christian Holler, Jesse Ruderman, Timothy Nikkel, Jeff Walden, Nils, Ms2ger, Abhishek Arya, and Cody Crews as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 17.0.6 ESR. You can find a link to the Mozilla advisories in the References section of this erratum.
