openSUSE Security Update : MozillaFirefox (openSUSE-SU-2010:0102-3)
Critical Nessus Plugin ID 45527
SynopsisThe remote openSUSE host is missing a security update.
DescriptionThis patch updates Mozilla Firefox to the 3.5.9 release.
It includes the 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.
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 2010-22 / 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.
