RedHat: RHSA-2016-0373:01 Critical: firefox security update
Summary
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,
