Description

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)

After installing the update, Firefox must be restarted for the changes to take effect.
