The browser engine in Mozilla Firefox 3.0.x before 3.0.18, 3.5.x before 3.5.8, and 3.6.x before 3.6.2; Thunderbird before 3.0.2; and SeaMonkey before 2.0.3 allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via vectors related to (1) layout/generic/nsBlockFrame.cpp and (2) the _evaluate function in modules/plugin/base/src/nsNPAPIPlugin.cpp.

From Red Hat Security Advisory 2010:0112 :

Updated firefox packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

Mozilla Firefox is an open source Web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

A use-after-free flaw was found in Firefox. Under low memory conditions, visiting a web page containing malicious content could result in Firefox executing arbitrary code with the privileges of the user running Firefox. (CVE-2009-1571)

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2010-0159, CVE-2010-0160)

Two flaws were found in the way certain content was processed. An attacker could use these flaws to create a malicious web page that could bypass the same-origin policy, or possibly run untrusted JavaScript. (CVE-2009-3988, CVE-2010-0162)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.0.18. You can find a link to the Mozilla advisories in the References section of this errata.

All Firefox users should upgrade to these updated packages, which contain Firefox version 3.0.18, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

The remote host is affected by the vulnerability described in GLSA-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.

Security issues were identified and fixed in firefox :

Security researcher regenrecht reported (via TippingPoint's Zero Day Initiative) a potential reuse of a deleted image frame in Firefox 3.6's handling of multipart/x-mixed-replace images. Although no exploit was shown, re-use of freed memory has led to exploitable vulnerabilities in the past (CVE-2010-0164).

Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. 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-2010-0165, CVE-2010-0167).

Mozilla developer Josh Soref of Nokia reported that documents failed to call certain security checks when attempting to preload images.
Although the image content is not available to the page, it is possible to specify protocols that are normally not allowed in a web page such as file:. This includes internal schemes implemented by add-ons that might perform privileged actions resulting in something like a Cross-Site Request Forgery (CSRF) attack against the add-on.
Potential severity would depend on the add-ons installed (CVE-2010-0168).

Mozilla developer Blake Kaplan reported that the window.location object was made a normal overridable JavaScript object in the Firefox 3.6 browser engine (Gecko 1.9.2) because new mechanisms were developed to enforce the same-origin policy between windows and frames. This object is unfortunately also used by some plugins to determine the page origin used for access restrictions. A malicious page could override this object to fool a plugin into granting access to data on another site or the local file system. The behavior of older Firefox versions has been restored (CVE-2010-0170).

Mozilla developer Justin Dolske reported that the new asynchronous Authorization Prompt (HTTP username and password) was not always attached to the correct window. Although we have not demonstrated this, it may be possible for a malicious page to convince a user to open a new tab or popup to a trusted service and then have the HTTP authorization prompt from the malicious page appear to be the login prompt for the trusted page. This potential attack is greatly mitigated by the fact that very few websites use HTTP authorization, preferring instead to use web forms and cookies (CVE-2010-0172).

Unspecified vulnerability in Mozilla Firefox 3.5.x through 3.5.8 allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly have unknown other impact via vectors that might involve compressed data, a different vulnerability than CVE-2010-1028 (CVE-2010-1122).

Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. 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-2010-0173, CVE-2010-0174)

Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that a select event handler for XUL tree items could be called after the tree item was deleted. This results in the execution of previously freed memory which an attacker could use to crash a victim's browser and run arbitrary code on the victim's computer (CVE-2010-0175).

Security researcher regenrecht reported via TippingPoint's Zero Day Initiative an error in the way <option> elements are inserted into a XUL tree <optgroup>. In certain cases, the number of references to an <option> element is under-counted so that when the element is deleted, a live pointer to its old location is kept around and may later be used. An attacker could potentially use these conditions to run arbitrary code on a victim's computer (CVE-2010-0176).

Security researcher regenrecht reported via TippingPoint's Zero Day Initiative an error in the implementation of the window.navigator.plugins object. When a page reloads, the plugins array would reallocate all of its members without checking for existing references to each member. This could result in the deletion of objects for which valid pointers still exist. An attacker could use this vulnerability to crash a victim's browser and run arbitrary code on the victim's machine (CVE-2010-0177).

Security researcher Paul Stone reported that a browser applet could be used to turn a simple mouse click into a drag-and-drop action, potentially resulting in the unintended loading of resources in a user's browser. This behavior could be used twice in succession to first load a privileged chrome: URL in a victim's browser, then load a malicious javascript: URL on top of the same document resulting in arbitrary script execution with chrome privileges (CVE-2010-0178).

Mozilla security researcher moz_bug_r_a4 reported that the XMLHttpRequestSpy module in the Firebug add-on was exposing an underlying chrome privilege escalation vulnerability. When the XMLHttpRequestSpy object was created, it would attach various properties of itself to objects defined in web content, which were not being properly wrapped to prevent their exposure to chrome privileged objects. This could result in an attacker running arbitrary JavaScript on a victim's machine, though it required the victim to have Firebug installed, so the overall severity of the issue was determined to be High (CVE-2010-0179).

phpBB developer Henry Sudhof reported that when an image tag points to a resource that redirects to a mailto: URL, the external mail handler application is launched. This issue poses no security threat to users but could create an annoyance when browsing a site that allows users to post arbitrary images (CVE-2010-0181).

Mozilla community member Wladimir Palant reported that XML documents were failing to call certain security checks when loading new content.
This could result in certain resources being loaded that would otherwise violate security policies set by the browser or installed add-ons (CVE-2010-0182).

Note that to benefit from the fix for CVE-2009-3555 added in nss-3.12.6, Firefox 3.6 users will need to set their security.ssl.require_safe_negotiation preference to true. In Mandriva the default setting is false due to problems with some common sites.

Since firefox-3.0.19 is the last 3.0.x release Mandriva opted to provide the latest 3.6.3 version for Mandriva Linux 2008.0/2009.0/2009.1/MES5/2010.0.

Packages for 2008.0 and 2009.0 are provided due to the Extended Maintenance Program for those products.

Additionally, some packages which require so, have been rebuilt and are being provided as updates.

Update :

Packages for 2009.0 are provided due to the Extended Maintenance Program.
