SuSE 10 Security Update : Mozilla Firefox (ZYPP Patch Number 6867)

This script is Copyright (C) 2010-2016 Tenable Network Security, Inc.

Synopsis :

The remote SuSE 10 host is missing a security-related patch.

Description :

Mozilla Firefox was upgraded to version 3.5.8, fixing various bugs and
security issues.

The following security issues have been 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 2010-01 / CVE-2010-0159)

- Security researcher Orlando Barrera II reported via
TippingPoint's Zero Day Initiative that Mozilla's
implementation of Web Workers contained an error in its
handling of array data types when processing posted
messages. This error could be used by an attacker to
corrupt heap memory and crash the browser, potentially
running arbitrary code on a victim's computer. (MFSA
2010-02 / CVE-2010-0160)

- Security researcher Alin Rad Pop of Secunia Research
reported that the HTML parser incorrectly freed used
memory when insufficient space was available to process
remaining input. Under such circumstances, memory
occupied by in-use objects was freed and could later be
filled with attacker-controlled text. These conditions
could result in the execution or arbitrary code if
methods on the freed objects were subsequently called.
(MFSA 2010-03 / CVE-2009-1571)

- Security researcher Hidetake Jo of Microsoft
Vulnerability Research reported that the properties set
on an object passed to showModalDialog were readable by
the document contained in the dialog, even when the
document was from a different domain. This is a
violation of the same-origin policy and could result in
a website running untrusted JavaScript if it assumed the
dialogArguments could not be initialized by another
site. (MFSA 2010-04 / CVE-2009-3988)

An anonymous security researcher, via TippingPoint's Zero Day
Initiative, also independently reported this issue to Mozilla.

- Mozilla security researcher Georgi Guninski reported
that when a SVG document which is served with
Content-Type: application/octet-stream is embedded into
another document via an tag with type='image/svg+xml',
the Content-Type is ignored and the SVG document is
processed normally. A website which allows arbitrary
binary data to be uploaded but which relies on
Content-Type: application/octet-stream to prevent script
execution could have such protection bypassed. An
attacker could upload a SVG document containing
JavaScript as a binary file to a website, embed the SVG
document into a malicous page on another site, and gain
access to the script environment from the SVG-serving
site, bypassing the same-origin policy. (MFSA 2010-05 /
