Scientific Linux Security Update : firefox on SL5.x, SL6.x, SL7.x i386/x86_64

Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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.
