Security update for Mozilla Firefox (important)

Mozilla Firefox has been updated to the 31.3ESR release fixing bugs and
security issues.

   *

     MFSA 2014-83 / CVE-2014-1588 / CVE-2014-1587: Mozilla developers and

community identified and fixed several memory safety bugs in the browser
engine used in Firefox and other Mozilla-based products. Some
of these bugs showed evidence of memory corruption under certain
circumstances, and we presume that with enough effort at least some
of these could be exploited to run arbitrary code.

   *

     MFSA 2014-85 / CVE-2014-1590: Security researcher Joe Vennix from

Rapid7 reported that passing a JavaScript object to XMLHttpRequest that
mimics an input stream will a crash. This crash is not exploitable and can
only be used for denial of service attacks.

   *

     MFSA 2014-87 / CVE-2014-1592: Security researcher Berend-Jan Wever

reported a use-after-free created by triggering the creation of a second
root element while parsing HTML written to a document created with
document.open(). This leads to a potentially exploitable crash.

   *

     MFSA 2014-88 / CVE-2014-1593: Security researcher Abhishek Arya

(Inferno) of the Google Chrome Security Team used the Address Sanitizer
tool to discover a buffer overflow during the parsing of media content.
This leads to a potentially exploitable crash.

   *

     MFSA 2014-89 / CVE-2014-1594: Security researchers Byoungyoung Lee,

Chengyu Song, and Taesoo Kim at the Georgia Tech Information Security
Center (GTISC) reported a bad casting from the BasicThebesLayer to
BasicContainerLayer, resulting in undefined behavior. This behavior is
potentially exploitable with some compilers but no clear mechanism to
trigger it through web content was identified.

     MFSA 2014-90 / CVE-2014-1595: Security researcher Kent Howard

reported an Apple issue present in OS X 10.10 (Yosemite) where log files
are created by the CoreGraphics framework of OS X in the /tmp local
directory. These log files contain a record of all inputs into Mozilla
programs during their operation. In versions of OS X from versions 10.6
through 10.9, the CoreGraphics had this logging ability but it was turned
off by default. In OS X 10.10, this logging was turned on by default for
some applications that use a custom memory allocator, such as jemalloc,
because of an initialization bug in the framework. This issue has been
addressed in Mozilla products by explicitly turning off the framework’s
logging of input events. On vulnerable systems, this issue can result in
private data such as usernames, passwords, and other inputed data being
saved to a log file on the local system.
