Problem description

This update brings Mozilla Firefox to security update version
Following security problems were fixed:
  • MFSA 2007-26 / CVE-2007-3844: Privilege escalation through chrome-loaded about:blank windows Mozilla researcher moz_bug_r_a4 reported that a flaw was introduced by the fix for MFSA 2007-20 that could enable privilege escalation attacks against addons that create "about:blank" windows and populate them in certain ways (including implicit "about:blank" document creation through data: or javascript: URLs in a new window).
  • MFSA 2007-29: Crashes with evidence of memory corruption As part of the Firefox update releases Mozilla developers fixed many bugs to improve the stability of the product. Some of these crashes 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-2007-5339 Browser crashes
    • CVE-2007-5340 JavaScript engine crashes
  • MFSA 2007-30 / CVE-2007-1095: onUnload Tailgating Michal Zalewski demonstrated that onUnload event handlers had access to the address of the new page about to be loaded, even if the navigation was triggered from outside the page content such as by using a bookmark, pressing the back button, or typing an address into the location bar. If the bookmark contained sensitive information in the URL the attacking page might be able to take advantage of it. An attacking page would also be able to redirect the user, perhaps to a phishing page that looked like the site the user thought they were about to visit.
  • MFSA 2007-31 / CVE-2007-2292: Digest authentication request splitting Security researcher Stefano Di Paola reported that Firefox did not properly validate the user ID when making an HTTP request using Digest Authentication to log into a web site. A malicious page could abuse this to inject arbitrary HTTP headers by including a newline character in the user ID followed by the injected header data. If the user were connecting through a proxy the attacker could inject headers that a proxy would interpret as two separate requests for different hosts.
  • MFSA 2007-32 / CVE-2007-3511 / CVE-2006-2894: File input focus stealing vulnerability A user on the forums named hong reported that a file upload control could be filled programmatically by switching page focus to the label before a file upload form control for selected keyboard events. An attacker could use this trick to steal files from the users' computer if the attacker knew the full pathnames to the desired fileis and could create a pretext that would convince the user to type long enough to produce all the necessary characters.
  • MFSA 2007-33 / CVE-2007-5334: XUL pages can hide the window titlebar Mozilla developer Eli Friedman discovered that web pages written in the XUL markup language (rather than the usual HTML) can hide their window's titlebar. It may have been possible to abuse this ablity to create more convincing spoof and phishing pages.
  • MFSA 2007-34 / CVE-2007-5337: Possible file stealing through sftp protocol On Linux machines with gnome-vfs support the smb: and sftp: URI schemes are available in Firefox. Georgi Guninski showed that if an attacker can store the attack page in a mutually accessible location on the target server (/tmp perhaps) and lure the victim into loading it, the attacker could potentially read any file owned by the victim from known locations on that server.
  • MFSA 2007-35 / CVE-2007-5338: XPCNativeWraper pollution using Script object Mozilla security researcher moz_bug_r_a4 reported that it was possible to use the Script object to modify XPCNativeWrappers in such a way that subsequent access by the browser chrome--such as by right-clicking to open a context menu--can cause attacker-supplied javascript to run with the same privileges as the user. This is similar to MFSA 2007-25 fixed in Firefox
Only Windows is affected by:
  • MFSA 2007-27 / CVE-2007-3845: Unescaped URIs passed to external programs This problem affects Windows only due to their handling of URI launchers.
  • MFSA 2007-28 / CVE-2006-4965: Code execution via QuickTime Media-link files Linux does not have .lnk files, nor Quicktime. Not affected.
  • MFSA 2007-36 / CVE-2007-4841 URIs with invalid %-encoding mishandled by Windows This problem does not affect Linux.
