This update brings Mozilla Firefox to security update version 2.0.0.8

Following security problems were fixed :

  - Privilege escalation through chrome-loaded about:blank     windows. (MFSA 2007-26 / CVE-2007-3844)

    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).

  - Crashes with evidence of memory corruption As part of     the Firefox 2.0.0.8 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. (MFSA 2007-29)

  - Browser crashes. (CVE-2007-5339)

  - JavaScript engine crashes. (CVE-2007-5340)

  - 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 2007-30 / CVE-2007-1095)

  - Digest authentication request splitting. (MFSA 2007-31 /     CVE-2007-2292)

    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 website. 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.

  - File input focus stealing vulnerability. (MFSA 2007-32 /     CVE-2007-3511 / CVE-2006-2894)

    A user on the Sla.ckers.org 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.

  - XUL pages can hide the window titlebar. (MFSA 2007-33 /     CVE-2007-5334)

    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 ability to create more     convincing spoof and phishing pages.

  - Possible file stealing through sftp protocol. (MFSA     2007-34 / CVE-2007-5337)

    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.

  - XPCNativeWraper pollution using Script object. (MFSA     2007-35 / CVE-2007-5338)

    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 2.0.0.5

Only Windows is affected by :

  - Unescaped URIs passed to external programs. (MFSA     2007-27 / CVE-2007-3845)

    This problem affects Windows only due to their handling     of URI launchers.

  - Code execution via QuickTime Media-link files. (MFSA     2007-28 / CVE-2006-4965)

    Linux does not have .lnk files, nor Quicktime. Not     affected.

  - URIs with invalid %-encoding mishandled by Windows.
    (MFSA 2007-36 / CVE-2007-4841)

    This problem does not affected Linux.

Various flaws were discovered in the layout and JavaScript engines. By tricking a user into opening a malicious web page, an attacker could execute arbitrary code with the user's privileges. (CVE-2007-5339, CVE-2007-5340)

Flaws were discovered in the file upload form control. By tricking a user into opening a malicious web page, an attacker could force arbitrary files from the user's computer to be uploaded without their consent. (CVE-2006-2894, CVE-2007-3511)

Michal Zalewski discovered that the onUnload event handlers were incorrectly able to access information outside the old page content. A malicious website could exploit this to modify the contents, or steal confidential data (such as passwords), of the next loaded web page.
(CVE-2007-1095)

Stefano Di Paola discovered that Thunderbird did not correctly request Digest Authentications. A malicious website could exploit this to inject arbitrary HTTP headers or perform session splitting attacks against proxies. (CVE-2007-2292)

Eli Friedman discovered that XUL could be used to hide a window's titlebar. A malicious website could exploit this to enhance their attempts at creating phishing websites. (CVE-2007-5334)

Georgi Guninski discovered that Thunderbird would allow file-system based web pages to access additional files. By tricking a user into opening a malicious web page from a gnome-vfs location, an attacker could steal arbitrary files from the user's computer. (CVE-2007-5337)

It was discovered that the XPCNativeWrappers were not safe in certain situations. By tricking a user into opening a malicious web page, an attacker could run arbitrary JavaScript with the user's privileges.
(CVE-2007-5338)

Please note that JavaScript is disabled by default for emails, and it is not recommended to enable it.

The version of Firefox installed on the remote Windows host is prior to 2.0.0.8. It is, therefore, affected by a vulnerability as referenced in the mfsa2007-33 advisory.

  - Mozilla Firefox before 2.0.0.8 and SeaMonkey before 1.1.5 can hide the window's titlebar when displaying     XUL markup language documents, which makes it easier for remote attackers to conduct phishing and spoofing     attacks by setting the hidechrome attribute. (CVE-2007-5334)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The installed version of Firefox is affected by various security issues, some of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2007-0979 advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several flaws were found in the way in which Firefox processed certain malformed web content. A web page containing malicious content could cause Firefox to crash or potentially execute arbitrary code as the user running Firefox. (CVE-2007-5338, CVE-2007-5339, CVE-2007-5340)

Several flaws were found in the way in which Firefox displayed malformed web content. A web page containing specially crafted content could potentially trick a user into surrendering sensitive information. (CVE-2007-1095, CVE-2007-3844, CVE-2007-3511, CVE-2007-5334)

A flaw was found in the Firefox sftp protocol handler. A malicious web page could access data from a remote sftp site, possibly stealing sensitive user data. (CVE-2007-5337)

A request-splitting flaw was found in the way in which Firefox generates a digest authentication request. If a user opened a specially crafted URL, it was possible to perform cross-site scripting attacks, web cache poisoning, or other, similar exploits.
