 Package name:           mozilla-firefox
 Advisory ID:            MDKSA-2005:120
 Date:                   July 13th, 2005

 Affected versions:	 10.2

 Problem Description:

 A number of vulnerabilities were reported and fixed in Firefox 1.0.5
 and Mozilla 1.7.9.  The following vulnerabilities have been backported
 and patched for this update:
 
 In several places the browser UI did not correctly distinguish between
 true user events, such as mouse clicks or keystrokes, and synthetic
 events genenerated by web content. The problems ranged from minor
 annoyances like switching tabs or entering full-screen mode, to a
 variant on MFSA 2005-34 Synthetic events are now prevented from
 reaching the browser UI entirely rather than depend on each potentially
 spoofed function to protect itself from untrusted events
 (MFSA 2005-45).
 
 Scripts in XBL controls from web content continued to be run even when
 Javascript was disabled. By itself this causes no harm, but it could be
 combined with most script-based exploits to attack people running
 vulnerable versions who thought disabling javascript would protect
 them.  In the Thunderbird and Mozilla Suite mail clients Javascript is
 disabled by default for protection against denial-of-service attacks
 and worms; this vulnerability could be used to bypass that protection
 (MFSA 2005-46).
 
 If an attacker can convince a victim to use the "Set As Wallpaper"
 context menu item on a specially crafted image then they can run
 arbitary code on the user's computer. The image "source" must be a
 javascript: url containing an eval() statement and such an image would
 get the "broken image" icon, but with CSS it could be made transparent
 and placed on top of a real image.  The attacker would have to convince
 the user to change their desktop background to the exploit image, and
 to do so by using the Firefox context menu rather than first saving the
 image locally and using the normal mechanism provided by their
 operating system.  This affects only Firefox 1.0.3 and 1.0.4; earlier
 versions are unaffected. The implementation of this feature in the
 Mozilla Suite is also unaffected (MFSA 2005-47).
 
 The InstallTrigger.install() method for launching an install accepts a
 callback function that will be called with the final success or error
 status. By forcing a page navigation immediately after calling the
 install method this callback function can end up running in the context
 of the new page selected by the attacker. This is true even if the user
 cancels the unwanted install dialog: cancel is an error status. This
 callback script can steal data from the new page such as cookies or
 passwords, or perform actions on the user's behalf such as make a
 purchase if the user is already logged into the target site.  In
 Firefox the default settings allow only http://addons.mozilla.org to
 bring up this install dialog. This could only be exploited if users
 have added questionable sites to the install whitelist, and if a
 malicious site can convince you to install from their site that's a
 much more powerful attack vector.  In the Mozilla Suite the whitelist
 feature is turned off by default, any site can prompt the user to
 install software and exploit this vulnerability.  The browser has been
 fixed to clear any pending callback function when switching to a new
 site (MFSA 2005-48).
 
 Sites can use the _search target to open links in the Firefox sidebar.
 A missing security check allows the sidebar to inject data: urls
 containing scripts into any page open in the browser. This could be
 used to steal cookies, passwords or other sensitive data
 (MFSA 2005-49).
 
 When InstallVersion.compareTo() is passed an object rather than a
 string it assumed the object was another InstallVersion without
 verifying it. When passed a different kind of object the browser would
 generally crash with an access violation.  shutdown has demonstrated
 that different javascript objects can be passed on some OS versions to
 get control over the instruction pointer. We assume this could be
 developed further to run arbitrary machine code if the attacker can get
 exploit code loaded at a predictable address (MFSA 2005-50).
 
 The original frame-injection spoofing bug was fixed in the Mozilla
 Suite 1.7 and Firefox 0.9 releases. This protection was accidentally
 bypassed by one of the fixes in the Firefox 1.0.3 and Mozilla Suite
 1.7.7 releases (MFSA 2005-51).
 
 A child frame can call top.focus() even if the framing page comes from
 a different origin and has overridden the focus() routine. The call is
 made in the context of the child frame. The attacker would look for a
 target site with a framed page that makes this call but doesn't verify
 that its parent comes from the same site. The attacker could steal
 cookies and passwords from the framed page, or take actions on behalf
 of a signed-in user. This attack would work only against sites that use
 frames in this manner (MFSA 2005-52).
 
 Several media players, for example Flash and QuickTime, support
 scripted content with the ability to open URLs in the default browser.
 The default behavior for Firefox was to replace the currently open
 browser window's content with the externally opened content. If the
 external URL was a javascript: url it would run as if it came from the
 site that served the previous content, which could be used to steal
 sensitive information such as login cookies or passwords. If the
 media player content first caused a privileged chrome: url to load then
 the subsequent javascript: url could execute arbitrary code.  External
 javascript: urls will now run in a blank context regardless of what
 content it's replacing, and external apps will no longer be able to
 load privileged chrome: urls in a browser window. The -chrome command
 line option to load chrome applications is still supported
 (MFSA 2005-53).
 
 Alerts and prompts created by scripts in web pages are presented with
 the generic title [JavaScript Application] which sometimes makes it
 difficult to know which site created them. A malicious page could
 attempt to cause a prompt to appear in front of a trusted site in an
 attempt to extract information such as passwords from the user.  In the
 fixed version these prompts will contain the hostname from the page
 which created it (MFSA 2005-54).
 
 Parts of the browser UI relied too much on DOM node names without
 taking different namespaces into account and verifying that nodes
 really were of the expected type. An XHTML document could be used to
 create fake <IMG> elements, for example, with content-defined
 properties that the browser would access as if they were the trusted
 built-in properties of the expected HTML elements.  The severity of the
 vulnerability would depend on what the attacker could convince the
 victim to do, but could result in executing user-supplied script with
 elevated "chrome" privileges. This could be used to install malicious
 software on the victim's machine (MFSA 2005-55).
 
 Improper cloning of base objects allowed web content scripts to walk up
 the prototype chain to get to a privileged object.  This could be used
 to execute code with enhanced privileges (MFSA 2005-56).
 
 The updated packages have been patched to address these issue.
