The remote SuSE 10 host is missing a security-related patch.
This security update brings Mozilla Firefox to version 184.108.40.206.
More details can be found on:
It includes fixes to the following security problems :
- Code execution through deleted frame reference.
(CVE-2006-3801 / MFSA 2006-44)
Thilo Girmann discovered that in certain circumstances a
properly cleared when the referenced content went away,
and he demonstrated that this pointer to a deleted
object could be used to execute native code supplied by
(CVE-2006-3677 / MFSA 2006-45)
An anonymous researcher for TippingPoint and the Zero
Day Initiative showed that when used in a web page Java
would reference properties of the window.navigator
object as it started up. If the page replaced the
navigator object before starting Java then the browser
would crash in a way that could be exploited to run
native code supplied by the attacker.
- Memory corruption with simultaneous events.
(CVE-2006-3113 / MFSA 2006-46)
Secunia Research has discovered a vulnerability in
Mozilla Firefox 1.5 branch, which can be exploited by
malicious people to compromise a user's system.
The vulnerability is caused due to an memory corruption
error within the handling of simultaneously happening
XPCOM events, which leads to use of a deleted timer
object. This generally results in a crash but
potentially could be exploited to execute arbitrary code
on a user's system when a malicious website is visited.
- Native DOM methods can be hijacked across domains.
(CVE-2006-3802 / MFSA 2006-47)
A malicious page can hijack native DOM methods on a
document object in another domain, which will run the
attacker's script when called by the victim page. This
could be used to steal login cookies, password, or other
sensitive data on the target page, or to perform actions
on behalf of a logged-in user.
Access checks on all other properties and document nodes
are performed correctly. This cross-site scripting (XSS)
attack is limited to pages which use standard DOM
methods of the top-level document object, such as
document.getElementById(). This includes many popular
sites, especially the newer ones that offer rich
interaction to the user.
H. D. Moore reported a testcase that was able to trigger
deleted a temporary variable still being used in the
creation of a new Function object. The resulting use of
a deleted object may be potentially exploitable to run
native code provided by the attacker.
- Heap buffer overwrite on malformed VCard. (CVE-2006-3804
/ MFSA 2006-49)
A VCard attachment with a malformed base64 field (such
as a photo) can trigger a heap buffer overwrite. These
have proven exploitable in the past, though in this case
the overwrite is accompanied by an integer underflow
that would attempt to copy more data than the typical
machine has, leading to a crash.
CVE-2006-3806 / MFSA 2006-50)
Mozilla developers found and fixed several potential
Igor Bukanov and shutdown found additional places where
an untimely garbage collection could delete a temporary
object that was in active use (similar to MFSA 2006-01 /
MFSA 2006-10). Some of these may allow an attacker to
run arbitrary code given the right conditions.
Georgi Guninski found potential integer overflow issues
with long strings in the toSource() methods of the
Object, Array and String objects as well as string
- Privilege escalation using named-functions and redefined
'new Object()'. (CVE-2006-3807 / MFSA 2006-51)
have a parent object created using the standard Object()
constructor (ECMA-specified behavior) and that this
constructor can be redefined by script (also
ECMA-specified behavior). If the Object() constructor is
changed to return a reference to a privileged object
with useful properties it is possible to have
attacker-supplied script excuted with elevated
privileges by calling the function. This could be used
to install malware or take other malicious actions.
Our fix involves calling the internal Object constructor
which appears to be what other ECMA-compatible
- PAC privilege escalation using Function.prototype.call.
(CVE-2006-3808 / MFSA 2006-52)
moz_bug_r_a4 reports that a malicious Proxy AutoConfig
(PAC) server could serve a PAC script that can execute
code with elevated privileges by setting the required
FindProxyForURL function to the eval method on a
privileged object that leaked into the PAC sandbox. By
redirecting the victim to a specially crafted URL --
easily done since the PAC script controls which proxy to
use -- the URL 'hostname' can be executed as privileged
A malicious proxy server can perform spoofing attacks on
the user so it was already important to use a
trustworthy PAC server.
- UniversalBrowserRead privilege escalation.
(CVE-2006-3809 / MFSA 2006-53)
shutdown reports that scripts granted the
UniversalBrowserRead privilege can leverage that into
the equivalent of the far more powerful
UniversalXPConnect since they are allowed to 'read' into
a privileged context. This allows the attacker the
ability to run scripts with the full privelege of the
user running the browser, possibly installing malware or
snooping on private data. This has been fixed so that
UniversalBrowserRead and UniversalBrowserWrite are
limited to reading from and writing into only
normally-privileged browser windows and frames.
- XSS with XPCNativeWrapper(window).Function(...).
(CVE-2006-3810 / MFSA 2006-54)
shutdown reports that cross-site scripting (XSS) attacks
could be performed using the construct
XPCNativeWrapper(window).Function(...), which created a
function that appeared to belong to the window in
question even after it had been navigated to the target
- Crashes with evidence of memory corruption.
(CVE-2006-3811 / MFSA 2006-55)
As part of the Firefox 220.127.116.11 stability and security
release, developers in the Mozilla community looked for
and fixed several crash bugs to improve the stability of
Mozilla clients. Some of these crashes showed evidence
of memory corruption that we presume could be exploited
to run arbitrary code with enough effort.
- chrome: scheme loading remote content. (CVE-2006-3812 /
Benjamin Smedberg discovered that chrome URL's could be
made to reference remote files, which would run scripts
with full privilege. There is no known way for web
content to successfully load a chrome: url, but if a
user could be convinced to do so manually (perhaps by
copying a link and pasting it into the location bar)
this could be exploited.
