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-2013-0744, CVE-2013-0746, CVE-2013-0750, CVE-2013-0753, CVE-2013-0754, CVE-2013-0762, CVE-2013-0766, CVE-2013-0767, CVE-2013-0769) A flaw was found in the way Chrome Object Wrappers were implemented. Malicious content could be used to cause Firefox to execute arbitrary code via plug-ins installed in Firefox. (CVE-2013-0758) A flaw in the way Firefox displayed URL values in the address bar could allow a malicious site or user to perform a phishing attack. (CVE-2013-0759) An information disclosure flaw was found in the way certain JavaScript functions were implemented in Firefox. An attacker could use this flaw to bypass Address Space Layout Randomization (ASLR) and other security restrictions. (CVE-2013-0748) For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 10.0.12 ESR. You can find a link to the Mozilla advisories in the References section of this erratum. Red Hat would like to thank the Mozilla project for reporting these issues.
