Ubuntu 8.04 LTS / 8.10 / 9.04 : thunderbird vulnerabilities (USN-782-1)

Ubuntu Security Notice (C) 2009-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Several flaws were discovered in the JavaScript engine of Thunderbird.
If a user had JavaScript enabled and were tricked into viewing
malicious web content, a remote attacker could cause a denial of
service or possibly execute arbitrary code with the privileges of the
user invoking the program. (CVE-2009-1303, CVE-2009-1305,
CVE-2009-1392, CVE-2009-1833, CVE-2009-1838)

Several flaws were discovered in the way Thunderbird processed
malformed URI schemes. If a user were tricked into viewing a malicious
website and had JavaScript and plugins enabled, a remote attacker
could execute arbitrary JavaScript or steal private data.
(CVE-2009-1306, CVE-2009-1307, CVE-2009-1309)

Cefn Hoile discovered Thunderbird did not adequately protect against
embedded third-party stylesheets. If JavaScript were enabled, an
attacker could exploit this to perform script injection attacks using
XBL bindings. (CVE-2009-1308)

Shuo Chen, Ziqing Mao, Yi-Min Wang, and Ming Zhang discovered that
Thunderbird did not properly handle error responses when connecting to
a proxy server. If a user had JavaScript enabled while using
Thunderbird to view websites and a remote attacker were able to
perform a man-in-the-middle attack, this flaw could be exploited to
view sensitive information. (CVE-2009-1836)

It was discovered that Thunderbird could be made to run scripts with
elevated privileges. If a user had JavaScript enabled while having
certain non-default add-ons installed and were tricked into viewing a
malicious website, an attacker could cause a chrome privileged object,
such as the browser sidebar, to run arbitrary code via interactions
with the attacker controlled website. (CVE-2009-1841).

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 9.3
