Summary
=======

Some vulnerabilities have been reported in Mozilla  Thunderbird,  which
can potentially be exploited by malicious people to compromise a user's
system.


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

CVE-2009-0771: The layout engine allows remote  attackers  to  cause  a
denial of service (crash)  and  possibly  execute  arbitrary  code  via
certain vectors that trigger memory corruption and assertion failures.



CVE-2009-0772: The layout engine allows remote  attackers  to  cause  a
denial of service (crash)  and  possibly  execute  arbitrary  code  via
vectors related to nsCSSStyleSheet::GetOwnerNode, events,  and  garbage
collection, which triggers memory corruption.



CVE-2009-0773: The JavaScript engine before allows remote attackers  to
cause a denial of service (crash) and possibly execute  arbitrary  code
via a splice of an array that contains "some non-set  elements,"  which
causes jsarray.cpp to pass an incorrect  argument  to  the  ResizeSlots
function,  which triggers  memory  corruption;  vectors   related   to
js_DecompileValueGenerator, jsopcode.cpp, __defineSetter__, and  watch,
which triggers an assertion failure or a segmentation fault; and
vectors related to gczeal, __defineSetter__,
and watch, which triggers a hang.


CVE-2009-0774: The layout engine allows remote  attackers  to  cause  a
denial of service (crash) and possibly execute arbitrary code via
vectors related to gczeal, a different vulnerability
than CVE-2009-0773.


CVE-2009-0775: Double free vulnerability  allows  remote  attackers
to execute arbitrary code via "cloned XUL DOM
elements which were linked as  a  parent  and  child,"  which  are  not
properly handled during garbage collection.



CVE-2009-0776: nsIRDFService allows  remote  attackers  to  bypass  the
same-origin  policy and  read  XML  data  from  another  domain  via  a
cross-domain redirect.



CVE-2009-0777: Thunderbird before 2.0.0.21 decodes invisible characters
when they are displayed in the location bar, which causes an  incorrect
address to be displayed and makes it easier  for  remote  attackers  to
spoof URLs and conduct phishing attacks.


Affected packages:

  Pardus 2008:
    thunderbird, all before 2.0.0.21-44-8


Resolution
==========

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

    pisi up thunderbird
