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-2015-2724, CVE-2015-2725, CVE-2015-2722,
CVE-2015-2727, CVE-2015-2728, CVE-2015-2729, CVE-2015-2731, CVE-2015-2733,
CVE-2015-2734, CVE-2015-2735, CVE-2015-2736, CVE-2015-2737, CVE-2015-2738,
CVE-2015-2739, CVE-2015-2740)

It was found that Firefox skipped key-pinning checks when handling an
error that could be overridden by the user (for example an expired
certificate error). This flaw allowed a user to override a pinned
certificate, which is an action the user should not be able to perform.
(CVE-2015-2741)

A flaw was discovered in Mozilla's PDF.js PDF file viewer. When combined
with another vulnerability, it could allow execution of arbitrary code
with the privileges of the user running Firefox. (CVE-2015-2743)

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