Pardus Linux Security Advisory 2008-85            security@pardus.org.tr
------------------------------------------------------------------------
     Date: 2008-12-23
 Severity: 5
     Type: Remote
------------------------------------------------------------------------

Summary
=======

Some vulnerabilities have been reported in Mozilla  Thunderbird,  which
can  be exploited  by  malicious  people  to  bypass  certain  security
restrictions,  disclose sensitive  information,   conduct   cross-site
scripting attacks, or potentially compromise a user's system.


Description
===========



1) Multiple errors in the layout engine can  be  exploited  to  corrupt
memory and potentially execute arbitrary code.



2) An error in the processing of XBL bindings can be exploited to bypass
the same-origin policy and read data from a target document in  another
domain.



Successful exploitation of this vulnerability requires that the  target
document contains a "" element and that the "id" of the read
binding is known.



3) An error in the feed  preview  functionality  can  be  exploited  to
execute arbitrary JavaScript code with chrome privileges.



This is related to vulnerability #3 in:

SA31984



4) An error exists when processing "XMLHttpRequest" requests to  a  web
server which redirects the browser via a 302 HTTP status code. This can
be exploited to bypass the same-origin policy  and  disclose  sensitive
information from another domain.



5) An error exists when  processing  JavaScript  URLs  redirecting  the
browser to another domain returning non-JavaScript data.  This  can  be
exploited to disclose sensitive information from the other domain via a
"window.onerror" event handler.



6) An error when processing URLs starting with  whitespace  or  certain
control characters can be exploited to  output  a  malformed  URL  when
rendering a hyperlink.



7) An error in the CSS parser when processing  "\0"  sequences  can  be
exploited to potentially bypass third party script sanitation routines.



8) An error when processing an XBL  binding  attached  to  an  unloaded
document can be exploited to bypass the same-origin policy and  execute
arbitrary JavaScript code in a different domain.



9) Two errors can  be  exploited  to  pollute  "XPCNativeWrappers"  and
execute arbitrary JavaScript code with chrome privileges.



10) Several errors in the session restore feature can be  exploited  to
execute arbitrary JavaScript code in a different domain or with  chrome
privileges.


Affected packages:

 Pardus 2008:
   thunderbird, all before 2.0.0.19-41-7


Resolution
==========

There are update(s) for thunderbird. You can update  them  via  Package
Manager or with a single command from console:

   pisi up thunderbird
