The Mozilla Foundation has reported numerous security vulnerabilities
related to Mozilla SeaMonkey.
||www-client/seamonkey on all architectures
The Mozilla SeaMonkey project is a community effort to deliver
production-quality releases of code derived from the application
formerly known as "Mozilla Application Suite".
The following vulnerabilities have been reported:
- Benjamin Smedberg discovered that chrome URL's could be made to
reference remote files.
- Developers in the Mozilla community
looked for and fixed several crash bugs to improve the stability of
Mozilla clients, which could lead to the execution of arbitrary code by
a remote attacker.
- "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 site.
- "shutdown" reports that scripts
granting 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.
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.
parent object created using the standard Object() constructor
(ECMA-specified behavior) and that this constructor can be redefined by
script (also ECMA-specified behavior).
- Igor Bukanov and
shutdown found additional places where an untimely garbage collection
could delete a temporary object that was in active use.
Guninski found potential integer overflow issues with long strings in
the toSource() methods of the Object, Array and String objects as well
as string function arguments.
- H. D. Moore reported a testcase
collection deleted a temporary variable still being used in the
creation of a new Function object.
- 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.
- Secunia Research has discovered a vulnerability which is caused due
to an memory corruption error within the handling of simultaneously
happening XPCOM events. This leads to use of a deleted timer
- 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.
reference to a frame or window was not properly cleared when the
referenced content went away.
A user can be enticed to open specially crafted URLs, visit webpages
These events could lead to the execution of arbitrary code, or the
installation of malware on the user's computer.
There is no known workaround at this time.
All Thunderbird users should upgrade to the latest version:
