   An update that fixes 18 vulnerabilities is now available.

Description:

   MozillaFirefox was updated to 14.0.1 to fix various bugs
   and security issues.


   Following security issues were fixed: MFSA 2012-42: Mozilla
   developers 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.

   CVE-2012-1949: Brian Smith, Gary Kwong, Christian Holler,
   Jesse Ruderman, Christoph Diehl, Chris Jones, Brad Lassey,
   and Kyle Huey reported memory safety problems and crashes
   that affect Firefox 13.

   CVE-2012-1948: Benoit Jacob, Jesse Ruderman, Christian
   Holler, and Bill McCloskey reported memory safety problems
   and crashes that affect Firefox ESR 10 and Firefox 13.


   MFSA 2012-43 / CVE-2012-1950: Security researcher Mario
   Gomes andresearch firm Code Audit Labs reported a mechanism
   to short-circuit page loads through drag and drop to the
   addressbar by canceling the page load. This causes the
   address of the previously site entered to be displayed in
   the addressbar instead of the currently loaded page. This
   could lead to potential phishing attacks on users.

   MFSA 2012-44 Google security researcher Abhishek Arya used
   the Address Sanitizer tool to uncover four issues: two
   use-after-free problems, one out of bounds read bug, and a
   bad cast. The first use-after-free problem is caused when
   an array of nsSMILTimeValueSpec objects is destroyed but
   attempts are made to call into objects in this array later.
   The second use-after-free problem is in
   nsDocument::AdoptNode when it adopts into an empty document
   and then adopts into another document, emptying the first
   one. The heap buffer overflow is in ElementAnimations when
   data is read off of end of an array and then pointers are
   dereferenced. The bad cast happens when
   nsTableFrame::InsertFrames is called with frames in
   aFrameList that are a mix of row group frames and column
   group frames. AppendFrames is not able to handle this mix.

   All four of these issues are potentially exploitable.
   CVE-2012-1951: Heap-use-after-free in
   nsSMILTimeValueSpec::IsEventBased CVE-2012-1954:
   Heap-use-after-free in nsDocument::AdoptNode CVE-2012-1953:
   Out of bounds read in ElementAnimations::EnsureStyleRuleFor
   CVE-2012-1952: Bad cast in nsTableFrame::InsertFrames


   MFSA 2012-45 / CVE-2012-1955: Security researcher Mariusz
   Mlynski reported an issue with spoofing of the location
   property. In this issue, calls to history.forward and
   history.back are used to navigate to a site while
   displaying the previous site in the addressbar but changing
   the baseURI to the newer site. This can be used for
   phishing by allowing the user input form or other data on
   the newer, attacking, site while appearing to be on the
   older, displayed site.

   MFSA 2012-46 / CVE-2012-1966: Mozilla security researcher
   moz_bug_r_a4 reported a cross-site scripting (XSS) attack
   through the context menu using a data: URL. In this issue,
   context menu functionality ("View Image", "Show only this
   frame", and "View background image") are disallowed in a
   javascript: URL but allowed in a data: URL, allowing for
   XSS. This can lead to arbitrary code execution.

   MFSA 2012-47 / CVE-2012-1957: Security researcher Mario
   Heiderich reported that javascript could be executed in the
   HTML feed-view using <embed> tag within the RSS
   <description>. This problem is due to <embed> tags not
   being filtered out during parsing and can lead to a
   potential cross-site scripting (XSS) attack. The flaw
   existed in a parser utility class and could affect other
   parts of the browser or add-ons which rely on that class to
   sanitize untrusted input.


   MFSA 2012-48 / CVE-2012-1958: Security researcher Arthur
   Gerkis used the Address Sanitizer tool to find a
   use-after-free in nsGlobalWindow::PageHidden when
   mFocusedContent is released and oldFocusedContent is used
   afterwards. This use-after-free could possibly allow for
   remote code execution.


   MFSA 2012-49 / CVE-2012-1959: Mozilla developer Bobby
   Holley found that same-compartment security wrappers (SCSW)
   can be bypassed by passing them to another compartment.
   Cross-compartment wrappers often do not go through SCSW,
   but have a filtering policy built into them. When an object
   is wrapped cross-compartment, the SCSW is stripped off and,
   when the object is read read back, it is not known that
   SCSW was previously present, resulting in a bypassing of
   SCSW. This could result in untrusted content having access
   to the XBL that implements browser functionality.

   MFSA 2012-50 / CVE-2012-1960: Google developer Tony Payne
   reported an out of bounds (OOB) read in QCMS, Mozillaâ??s
   color management library. With a carefully crafted color
   profile portions of a user's memory could be incorporated
   into a transformed image and possibly deciphered.
