Ubuntu Security Notice USN-3165-1
January 28, 2017

thunderbird vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- - Ubuntu 16.10
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS
- - Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

Software Description:
- - thunderbird: Mozilla Open Source mail and newsgroup client

Details:

Multiple memory safety issues were discovered in Thunderbird. If a user were
tricked in to opening a specially crafted message, an attacker could
potentially exploit these to cause a denial of service via application
crash, or execute arbitrary code. (CVE-2016-9893, CVE-2017-5373)

Andrew Krasichkov discovered that event handlers on <marquee> elements
were executed despite a Content Security Policy (CSP) that disallowed
inline JavaScript. If a user were tricked in to opening a specially
crafted website in a browsing context, an attacker could potentially
exploit this to conduct cross-site scripting (XSS) attacks.
(CVE-2016-9895)

A memory corruption issue was discovered in WebGL in some circumstances.
If a user were tricked in to opening a specially crafted website in a
browsing context, an attacker could potentially exploit this to cause a
denial of service via application crash, or execute arbitrary code.
(CVE-2016-9897)

A use-after-free was discovered when manipulating DOM subtrees in the
Editor. If a user were tricked in to opening a specially crafted website
in a browsing context, an attacker could potentially exploit this to
cause a denial of service via application crash, or execute arbitrary
code. (CVE-2016-9898)

A use-after-free was discovered when manipulating DOM events and audio
elements. If a user were tricked in to opening a specially crafted website
in a browsing context, an attacker could potentially exploit this to
cause a denial of service via application crash, or execute arbitrary
code. (CVE-2016-9899)

It was discovered that external resources that should be blocked when
loading SVG images can bypass security restrictions using data: URLs. An
attacker could potentially exploit this to obtain sensitive information.
(CVE-2016-9900)

Jann Horn discovered that JavaScript Map/Set were vulnerable to timing
attacks. If a user were tricked in to opening a specially crafted website
in a browsing context, an attacker could potentially exploit this to
obtain sensitive information across domains. (CVE-2016-9904)

A crash was discovered in EnumerateSubDocuments while adding or removing
sub-documents. If a user were tricked in to opening a specially crafted
website in a browsing context, an attacker could potentially exploit this
to execute arbitrary code. (CVE-2016-9905)

JIT code allocation can allow a bypass of ASLR protections in some
circumstances. If a user were tricked in to opening a specially crafted
website in a browsing context, an attacker could potentially exploit this
to cause a denial of service via application crash, or execute arbitrary
code. (CVE-2017-5375)

Nicolas Grégoire discovered a use-after-free when manipulating XSL in
XSLT documents in some circumstances. If a user were tricked in to opening
a specially crafted website in a browsing context, an attacker could
potentially exploit this to cause a denial of service via application
crash, or execute arbitrary code. (CVE-2017-5376)

Jann Horn discovered that an object's address could be discovered through
hashed codes of JavaScript objects shared between pages. If a user were
tricked in to opening a specially crafted website in a browsing context,
an attacker could potentially exploit this to obtain sensitive
information. (CVE-2017-5378)

A use-after-free was discovered during DOM manipulation of SVG content in
some circumstances. If a user were tricked in to opening a specially
crafted website in a browsing context, an attacker could potentially
exploit this to cause a denial of service via application crash, or
execute arbitrary code. (CVE-2017-5380)

Armin Razmjou discovered that certain unicode glyphs do not trigger
punycode display. If a user were tricked in to opening a specially crafted
website in a browsing context, an attacker could potentially exploit this
to spoof the URL bar contents. (CVE-2017-5383)

Jerri Rice discovered insecure communication methods in the Dev Tools JSON
Viewer. An attacker could potentially exploit this to gain additional
privileges. (CVE-2017-5390)

Filipe Gomes discovered a use-after-free in the media decoder in some
circumstances. If a user were tricked in to opening a specially crafted
website in a browsing context, an attacker could potentially exploit this
to cause a denial of service via application crash, or execute arbitrary
code. (CVE-2017-5396)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.10:
  thunderbird                     1:45.7.0+build1-0ubuntu0.16.10.1

Ubuntu 16.04 LTS:
  thunderbird                     1:45.7.0+build1-0ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  thunderbird                     1:45.7.0+build1-0ubuntu0.14.04.1

Ubuntu 12.04 LTS:
  thunderbird                     1:45.7.0+build1-0ubuntu0.12.04.1
