Description: Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox. A flaw was 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-2015-4497) A flaw was found in the way Firefox handled installation of add-ons. An attacker could use this flaw to bypass the add-on installation prompt, and trick the user inso installing an add-on from a malicious source. (CVE-2015-4498) Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Jean-Max Reymond, Ucha Gobejishvili, and Bas Venis as the original reporters of these issues. All Firefox users should upgrade to these updated packages, which contain Firefox version 38.2.1 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5.
