The Mozilla Foundation has reported numerous security vulnerabilities
related to Mozilla Thunderbird.
||mail-client/mozilla-thunderbird on all architectures
||mail-client/mozilla-thunderbird-bin on all architectures
The Mozilla Thunderbird mail client is a redesign of the Mozilla Mail
component. The goal is to produce a cross-platform stand-alone mail
application using XUL (XML User Interface Language).
The following vulnerabilities have been reported:
- Benjamin Smedberg discovered that chrome URLss could be made to
reference remote files.
- Developers in the Mozilla community
looked for and fixed several crash bugs to improve the stability of
- "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.
using the standard Object() constructor (ECMA-specified behavior) and
that this constructor can be redefined by script (also ECMA-specified
- Igor Bukanov and shutdown found additional places
where an untimely garbage collection could delete a temporary object
that was in active use.
- 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 function
- H. D. Moore reported a testcase that was able to
temporary variable still being used in the creation of a new Function
- 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 object.
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.
