Multiple vulnerabilities has been found and corrected in
mozilla-thunderbird:

dom/base/nsJSEnvironment.cpp in Mozilla Firefox 3.5.x before 3.5.11
and 3.6.x before 3.6.7, Thunderbird 3.0.x before 3.0.6 and 3.1.x
before 3.1.1, and SeaMonkey before 2.0.6 does not properly suppress
a script's URL in certain circumstances involving a redirect and an
error message, which allows remote attackers to obtain sensitive
information about script parameters via a crafted HTML document,
related to the window.onerror handler (CVE-2010-2754).

Mozilla Firefox permits cross-origin loading of CSS stylesheets
even when the stylesheet download has an incorrect MIME type and the
stylesheet document is malformed, which allows remote HTTP servers
to obtain sensitive information via a crafted document (CVE-2010-0654).

The importScripts Web Worker method in Mozilla Firefox 3.5.x before
3.5.11 and 3.6.x before 3.6.7, Thunderbird 3.0.x before 3.0.6 and
3.1.x before 3.1.1, and SeaMonkey before 2.0.6 does not verify that
content is valid JavaScript code, which allows remote attackers to
bypass the Same Origin Policy and obtain sensitive information via
a crafted HTML document (CVE-2010-1213).

Integer overflow in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x
before 3.6.7, Thunderbird 3.0.x before 3.0.6 and 3.1.x before
3.1.1, and SeaMonkey before 2.0.6 allows remote attackers to execute
arbitrary code via a large selection attribute in a XUL tree element
(CVE-2010-2753).

Integer overflow in an array class in Mozilla Firefox 3.5.x before
3.5.11 and 3.6.x before 3.6.7, Thunderbird 3.0.x before 3.0.6 and 3.1.x
before 3.1.1, and SeaMonkey before 2.0.6 allows remote attackers to
execute arbitrary code by placing many Cascading Style Sheets (CSS)
values in an array (CVE-2010-2752).

Multiple unspecified vulnerabilities in the browser engine in Mozilla
Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, Thunderbird 3.0.x
before 3.0.6 and 3.1.x before 3.1.1, and SeaMonkey before 2.0.6 allow
remote attackers to cause a denial of service (memory corruption and
application crash) or possibly execute arbitrary code via unknown
vectors (CVE-2010-1211).
