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

Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.
