The installed version of Firefox is earlier than 3.5.9.  Such versions are potentially affected by the following security issues :

  - Multiple crashes can result in arbitrary code execution.
    (MFSA 2010-16)

  - A select event handler for XUL tree items can be called     after the item is deleted. (MFSA 2010-17)

  - An error exists in the way '<option>' elements are     inserted into an XUL tree '<optgroup>' (MFSA 2010-18)

  - An error exists in the implementation of the     'windows.navigator.plugins' object. (MFSA 2010-19)

  - A browser applet can 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. (MFSA 2010-20)

  - Session renegotiations are not handled properly, which     can be exploited to insert arbitrary plaintext by a     man-in-the-middle. (MFSA 2010-22)

  - When an image points to a resource that redirects to a     'mailto:' URL, the external mail handler application is     launched. (MFSA 2010-23)     
  - XML documents fail to call certain security checks when     loading new content. (MFSA 2010-24)

This patch updates Mozilla XULRunner 3.0 engine the 1.9.0.19 release.

It includes also following security fixes: MFSA 2010-16: 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.

MFSA 2010-17 / CVE-2010-0175: 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.

MFSA 2010-18 / CVE-2010-0176: 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.

MFSA 2010-19 / CVE-2010-0177: 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.

MFSA 2010-20 / CVE-2010-0178: 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.

MFSA 2010-21 / CVE-2010-0179: 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.

MFSA 2010-22 / CVE-2009-3555: Mozilla developers added support in the Network Security Services module for preventing a type of man-in-the-middle attack against TLS using forced renegotiation.

Note that to benefit from the fix, Firefox 3.6 and Firefox 3.5 users will need to set their security.ssl.require_safe_negotiation preference to true. Firefox 3 does not contain the fix for this issue.

MFSA 2010-23 / CVE-2010-0181: 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.

MFSA 2010-24 / CVE-2010-0182: 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.

This patch updates Mozilla Firefox from the 3.0 stable branch to the 3.5.9 release.

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.

Mozilla SeaMonkey was updated to version 2.0.4 fixing lots of bugs and security issues.

Following security issues were fixed: MFSA 2010-16: Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products.

Updated SeaMonkey packages that fix several security issues are now available for Red Hat Enterprise Linux 3 and 4.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

SeaMonkey is an open source Web browser, email and newsgroup client, IRC chat client, and HTML editor.

Several use-after-free flaws were found in SeaMonkey. Visiting a web page containing malicious content could result in SeaMonkey executing arbitrary code with the privileges of the user running SeaMonkey.
(CVE-2010-0175, CVE-2010-0176, CVE-2010-0177)

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2010-0174)

All SeaMonkey users should upgrade to these updated packages, which correct these issues. After installing the update, SeaMonkey must be restarted for the changes to take effect.

Mozilla Firefox was updated to version 3.5.9 fixing lots of bugs and security issues.

The following security issues were fixed :

Note that to benefit from the fix, Firefox 3.6 and Firefox 3.5 users will need to set their security.ssl.require_safe_negotiation preference to true. Firefox 3 does not contain the fix for this issue.

  - 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. (MFSA 2010-23 /     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. (MFSA 2010-24 / CVE-2010-0182)
