Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : thunderbird vulnerabilities (USN-1551-1)

Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Gary Kwong, Christian Holler, Jesse Ruderman, Steve Fink, Bob Clary,
Andrew Sutherland, Jason Smith, John Schoenick, Vladimir Vukicevic and
Daniel Holbert discovered memory safety issues affecting Thunderbird.
If the user were tricked into opening a specially crafted E-Mail, an
attacker could exploit these to cause a denial of service via
application crash, or potentially execute code with the privileges of
the user invoking Thunderbird. (CVE-2012-1970, CVE-2012-1971)

Abhishek Arya discovered multiple use-after-free vulnerabilities. If
the user were tricked into opening a specially crafted E-Mail, an
attacker could exploit these to cause a denial of service via
application crash, or potentially execute code with the privileges of
the user invoking Thunderbird. (CVE-2012-1972, CVE-2012-1973,
CVE-2012-1974, CVE-2012-1975, CVE-2012-1976, CVE-2012-3956,
CVE-2012-3957, CVE-2012-3958, CVE-2012-3959, CVE-2012-3960,
CVE-2012-3961, CVE-2012-3962, CVE-2012-3963, CVE-2012-3964)

Mariusz Mlynsk discovered that it is possible to shadow the location
object using Object.defineProperty. This could potentially result in a
cross-site scripting (XSS) attack against plugins. With cross-site
scripting vulnerabilities, if a user were tricked into viewing a
specially crafted E-Mail, a remote attacker could exploit this to
modify the contents or steal confidential data within the same domain.
(CVE-2012-1956)

Frédéric Hoguin discovered that bitmap format images with a negative
height could potentially result in memory corruption. If the user were
tricked into opening a specially crafted image, an attacker could
exploit this to cause a denial of service via application crash, or
potentially execute code with the privileges of the user invoking
Thunderbird. (CVE-2012-3966)

It was discovered that Thunderbird's WebGL implementation was
vulnerable to multiple memory safety issues. If the user were tricked
into opening a specially crafted E-Mail, an attacker could exploit
these to cause a denial of service via application crash, or
potentially execute code with the privileges of the user invoking
Thunderbird. (CVE-2012-3967, CVE-2012-3968)

Arthur Gerkis discovered multiple memory safety issues in
Thunderbird's Scalable Vector Graphics (SVG) implementation. If the
user were tricked into opening a specially crafted image, an attacker
could exploit these to cause a denial of service via application
crash, or potentially execute code with the privileges of the user
invoking Thunderbird. (CVE-2012-3969, CVE-2012-3970)

Christoph Diehl discovered multiple memory safety issues in the
bundled Graphite 2 library. If the user were tricked into opening a
specially crafted E-Mail, an attacker could exploit these to cause a
denial of service via application crash, or potentially execute code
with the privileges of the user invoking Thunderbird. (CVE-2012-3971)

Nicolas Grégoire discovered an out-of-bounds read in the
format-number feature of XSLT. This could potentially cause inaccurate
formatting of numbers and information leakage. (CVE-2012-3972)

It was discovered that when the DOMParser is used to parse text/html
data in a Thunderbird extension, linked resources within this HTML
data will be loaded. If the data being parsed in the extension is
untrusted, it could lead to information leakage and potentially be
combined with other attacks to become exploitable. (CVE-2012-3975)

It was discovered that, in some instances, certain security checks in
the location object could be bypassed. This could allow for the
loading of restricted content and can potentially be combined with
other issues to become exploitable. (CVE-2012-3978)

Colby Russell discovered that eval in the web console can execute
injected code with chrome privileges, leading to the running of
malicious code in a privileged context. If the user were tricked into
opening a specially crafted E-Mail, an attacker could exploit this to
cause a denial of service via application crash, or potentially
execute code with the privileges of the user invoking Thunderbird.
(CVE-2012-3980).

Solution :

Update the affected thunderbird package.
