SuSE 11 Security Update : Mozilla XULrunner (SAT Patch Number 2255)

critical Nessus Plugin ID 50950

Language:

Synopsis

The remote SuSE 11 host is missing one or more security updates.

Description

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. (MFSA 2010-16)

References

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)

- 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 2010-17 / 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. (MFSA 2010-18 / 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. (MFSA 2010-19 / 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. (MFSA 2010-20 / 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. (MFSA 2010-21 / CVE-2010-0179)

- 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. (MFSA 2010-22 / CVE-2009-3555)

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)
