Details

Jeff Gilbert and Henrik Skupin discovered multiple memory safety issues
in Thunderbird. If the user were tricked in to 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-2013-1701)

It was discovered that a document's URI could be set to the URI of
a different document. If a user had scripting enabled, an attacker
could potentially exploit this to conduct cross-site scripting (XSS)
attacks. (CVE-2013-1709)

A flaw was discovered when generating a CRMF request in certain
circumstances. If a user had scripting enabled, an attacker could
potentially exploit this to conduct cross-site scripting (XSS) attacks,
or execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2013-1710)

Cody Crews discovered that some Javascript components performed security
checks against the wrong URI, potentially bypassing same-origin policy
restrictions. If a user had scripting enabled, an attacker could exploit
this to conduct cross-site scripting (XSS) attacks or install addons
from a malicious site. (CVE-2013-1713)

Federico Lanusse discovered that web workers could bypass cross-origin
checks when using XMLHttpRequest. If a user had scripting enabled, an
attacker could potentially exploit this to conduct cross-site scripting
(XSS) attacks. (CVE-2013-1714)

Georgi Guninski and John Schoenick discovered that Java applets could
access local files under certain circumstances. If a user had scripting
enabled, an attacker could potentially exploit this to steal confidential
data. (CVE-2013-1717)

Update instructions

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

Ubuntu 13.04
