Mozilla Thunderbird < 45.6 Multiple Vulnerabilities

Synopsis :

The remote Windows host contains a mail client that is affected by
multiple vulnerabilities.

Description :

The version of Mozilla Thunderbird installed on the remote Windows
host is prior to 45.6. It is, therefore, affected by the following
vulnerabilities :

- Multiple memory corruption issues exists, such as when
handling document state changes or HTML5 content, or
else due to dereferencing already freed memory or
improper validation of user-supplied input. An
unauthenticated, remote attacker can exploit these to
cause a denial of service condition or the execution of
arbitrary code. (CVE-2016-9893)

- A security bypass vulnerability exists due to event
handlers for marquee elements being executed despite a
Content Security Policy (CSP) that disallowed inline
JavaScript. An unauthenticated, remote attacker can
exploit this to impact integrity. (CVE-2016-9895)

- A memory corruption issue exists in libGLES when WebGL
functions use a vector constructor with a varying array
within libGLES. An unauthenticated, remote attacker can
exploit this to cause a denial of service condition or
the execution of arbitrary code. (CVE-2016-9897)

- A use-after-free error exists in Editor, specifically
within file editor/libeditor/HTMLEditor.cpp, when
handling DOM subtrees. An unauthenticated, remote
attacker can exploit this to cause a denial of service
condition or the execution of arbitrary code.
(CVE-2016-9898)

- A use-after-free error exists in the
nsNodeUtils::CloneAndAdopt() function within file
dom/base/nsNodeUtils.cpp, while manipulating DOM events
and removing audio elements, due to improper handling of
failing node adoption. An unauthenticated, remote
attacker can exploit this to cause a denial of service
condition or the execution of arbitrary code.
(CVE-2016-9899)

- A security bypass vulnerability exists in the
nsDataDocumentContentPolicy::ShouldLoad() function
within file dom/base/nsDataDocumentContentPolicy.cpp
that allows external resources to be inappropriately
loaded by SVG images by utilizing 'data:' URLs. An
unauthenticated, remote attacker can exploit this to
disclose sensitive cross-domain information.
(CVE-2016-9900)

- An information disclosure vulnerability exists that
allows an unauthenticated, remote attacker to determine
whether an atom is used by another compartment or zone
in specific contexts, by utilizing a JavaScript Map/Set
timing attack. (CVE-2016-9904)

- A flaw exists in the nsDocument::EnumerateSubDocuments()
function within file dom/base/nsDocument.cpp when adding
and removing sub-documents. An unauthenticated, remote
attacker can exploit this, via a specially crafted web
page, to corrupt memory, resulting in a denial of
service condition or the execution of arbitrary code.
(CVE-2016-9905)
