Update to new upstream SeaMonkey version 2.0.4, fixing multiple security issues detailed in the upstream advisories:
http://www.mozilla.org/security/known- vulnerabilities/seamonkey20.html#seamonkey2.0.4 CVE-2010-0173 CVE-2010-0174 CVE-2010-0175 CVE-2010-0176 CVE-2010-0177 CVE-2010-0178 CVE-2010-0181 CVE-2010-0182

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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)

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

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.

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

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

A flaw was found in Firefox that could allow an applet to generate a drag and drop action from a mouse click. Such an action could be used to execute arbitrary JavaScript with the privileges of the user running Firefox. (CVE-2010-0178)

A privilege escalation flaw was found in Firefox when the Firebug add-on is in use. The XMLHttpRequestSpy module in the Firebug add-on exposes a Chrome privilege escalation flaw that could be used to execute arbitrary JavaScript with the privileges of the user running Firefox. (CVE-2010-0179)

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-2010-0174)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.0.19. You can find a link to the Mozilla advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which contain Firefox version 3.0.19, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

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.

Martijn Wargers, Josh Soref, and Jesse Ruderman reported crashes in the browser engine that affected Firefox 3.5 and Firefox 3.6.
(CVE-2010-0173)

Jesse Ruderman and Ehsan Akhgari reported crashes that affected all supported versions of the browser engine. (CVE-2010-0174)

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.

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.

Mozilla XULRunner was updated to version 1.9.0.19 fixing lots of bugs and security issues.

The following security issues were fixed :

  - 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.
