Security issues were identified and fixed in firefox and
mozilla-thinderbird:

Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird
before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7
do not properly restrict read access to the statusText property of
XMLHttpRequest objects, which allows remote attackers to discover
the existence of intranet web servers via cross-origin requests
(CVE-2010-2764).

Cross-site scripting (XSS) vulnerability in Mozilla Firefox before
3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x
before 3.1.3, and SeaMonkey before 2.0.7 allows user-assisted remote
attackers to inject arbitrary web script or HTML via a selection that
is added to a document in which the designMode property is enabled
(CVE-2010-2769).

Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird
before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 do
not properly restrict use of the type attribute of an OBJECT element
to set a document's charset, which allows remote attackers to bypass
cross-site scripting (XSS) protection mechanisms via UTF-7 encoding
(CVE-2010-2768).

The XPCSafeJSObjectWrapper class in the SafeJSObjectWrapper (aka
SJOW) implementation in Mozilla Firefox 3.6.x before 3.6.9 and
Thunderbird 3.1.x before 3.1.3 does not properly restrict objects
at the end of scope chains, which allows remote attackers to execute
arbitrary JavaScript code with chrome privileges via vectors related
to a chrome privileged object and a chain ending in an outer object
(CVE-2010-2762).

The normalizeDocument function in Mozilla Firefox before 3.5.12 and
3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3,
and SeaMonkey before 2.0.7 does not properly handle the removal of
DOM nodes during normalization, which might allow remote attackers
to execute arbitrary code via vectors involving access to a deleted
object (CVE-2010-2766).

The nsTreeContentView function in Mozilla Firefox before 3.5.12 and
3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3,
and SeaMonkey before 2.0.7 does not properly handle node removal in
XUL trees, which allows remote attackers to execute arbitrary code
via vectors involving access to deleted memory, related to a dangling
pointer vulnerability. (CVE-2010-3167)

Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird
before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 do not
properly restrict the role of property changes in triggering XUL tree
removal, which allows remote attackers to cause a denial of service
(deleted memory access and application crash) or possibly execute
arbitrary code by setting unspecified properties (CVE-2010-3168).

Use-after-free vulnerability in the nsTreeSelection function in Mozilla
Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before
3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 might allow
remote attackers to execute arbitrary code via vectors involving a XUL
tree selection, related to a dangling pointer vulnerability. NOTE:
this issue exists because of an incomplete fix for CVE-2010-2753
(CVE-2010-2760).

Integer overflow in the FRAMESET element implementation in Mozilla
Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7
and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 might allow remote
attackers to execute arbitrary code via a large number of values in the
cols (aka columns) attribute, leading to a heap-based buffer overflow
(CVE-2010-2765).

Heap-based buffer overflow in the nsTextFrameUtils::TransformText
function in Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9,
Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before
2.0.7 might allow remote attackers to execute arbitrary code via a
bidirectional text run (CVE-2010-3166).

The navigator.plugins implementation in Mozilla Firefox before 3.5.12
and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before
3.1.3, and SeaMonkey before 2.0.7 does not properly handle destruction
of the DOM plugin array, which might allow remote attackers to cause
a denial of service (application crash) or execute arbitrary code
via crafted access to the navigator object, related to a dangling
pointer vulnerability. (CVE-2010-2767)

Multiple unspecified vulnerabilities in the browser engine in
Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird
before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 allow
remote attackers to cause a denial of service (memory corruption and
application crash) or possibly execute arbitrary code via unknown
vectors (CVE-2010-3169).

Packages for 2008.0 and 2009.0 are provided as of the Extended
Maintenance Program. Please visit this link to learn more:
