Ubuntu 12.04 LTS / 12.10 / 13.04 : thunderbird vulnerabilities (USN-1891-1)

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


Synopsis :

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

Description :

Multiple memory safety issues were discovered in Thunderbird. If the
user were tricked into opening a specially crafted message with
scripting enabled, an attacker could possibly exploit these to cause a
denial of service via application crash, or potentially execute
arbitrary code with the privileges of the user invoking Thunderbird.
(CVE-2013-1682)

Abhishek Arya discovered multiple use-after-free bugs. If the user
were tricked into opening a specially crafted message with scripting
enabled, an attacker could possibly exploit these to execute arbitrary
code with the privileges of the user invoking Thunderbird.
(CVE-2013-1684, CVE-2013-1685, CVE-2013-1686)

Mariusz Mlynski discovered that user defined code within the XBL scope
of an element could be made to bypass System Only Wrappers (SOW). If a
user had scripting enabled, an attacker could potentially exploit this
to execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2013-1687)

A crash was discovered when reloading a page that contained content
using the onreadystatechange event. If a user had scripting enabled,
an attacker could potentially exploit this to execute arbitrary code
with the privileges of the user invoking Thunderbird. (CVE-2013-1690)

Johnathan Kuskos discovered that Thunderbird sent data in the body of
XMLHttpRequest HEAD requests. If a user had scripting enabled, an
attacker could exploit this to conduct Cross-Site Request Forgery
(CSRF) attacks. (CVE-2013-1692)

Paul Stone discovered a timing flaw in the processing of SVG images
with filters. If a user had scripting enabled, an attacker could
exploit this to view sensitive information. (CVE-2013-1693)

Boris Zbarsky discovered a flaw in PreserveWrapper. If a user had
scripting enabled, an attacker could potentially exploit this to cause
a denial of service via application crash, or execute code with the
privileges of the user invoking Thunderbird. (CVE-2013-1694)

It was discovered that XrayWrappers could be bypassed to call
content-defined methods in certain circumstances. If a user had
scripting enabled, an attacker could exploit this to cause undefined
behaviour. (CVE-2013-1697).

Solution :

Update the affected thunderbird package.

Risk factor :

Critical / CVSS Base Score : 10.0
