openSUSE Security Update : mozilla-xulrunner190 (mozilla-xulrunner190-2261)

This script is Copyright (C) 2010-2014 Tenable Network Security, Inc.

Synopsis :

The remote openSUSE host is missing a security update.

Description :

This patch updates Mozilla XULRunner 3.0 engine the 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. References

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 2010-20 / 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

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

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.
