3. 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-2016-1952, CVE-2016-1954, CVE-2016-1957, CVE-2016-1958,
CVE-2016-1960, CVE-2016-1961, CVE-2016-1962, CVE-2016-1973, CVE-2016-1974,
CVE-2016-1964, CVE-2016-1965, CVE-2016-1966)
Multiple security flaws were found in the graphite2 font library shipped
with Firefox. 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-2016-1977, CVE-2016-2790, CVE-2016-2791,
CVE-2016-2792, CVE-2016-2793, CVE-2016-2794, CVE-2016-2795, CVE-2016-2796,
CVE-2016-2797, CVE-2016-2798, CVE-2016-2799, CVE-2016-2800, CVE-2016-2801,
CVE-2016-2802)
