Ubuntu Security Notice (C) 2008-2013 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 :

It was discovered that the same-origin check in Thunderbird could be
bypassed. If a user had JavaScript enabled and were tricked into
opening a malicious website, an attacker may be able to execute
JavaScript in the context of a different website. (CVE-2008-3835)

Several problems were discovered in the browser engine of Thunderbird.
If a user had JavaScript enabled, this could allow an attacker to
execute code with chrome privileges. (CVE-2008-4058, CVE-2008-4059,
CVE-2008-4060)

Drew Yao, David Maciejak and other Mozilla developers found several
problems in the browser engine of Thunderbird. If a user had
JavaScript enabled and were tricked into opening a malicious web page,
an attacker could cause a denial of service or possibly execute
arbitrary code with the privileges of the user invoking the program.
(CVE-2008-4061, CVE-2008-4062, CVE-2008-4063, CVE-2008-4064)

Dave Reed discovered a flaw in the JavaScript parsing code when
processing certain BOM characters. An attacker could exploit this to
bypass script filters and perform cross-site scripting attacks if a
user had JavaScript enabled. (CVE-2008-4065)

Gareth Heyes discovered a flaw in the HTML parser of Thunderbird. If a
user had JavaScript enabled and were tricked into opening a malicious
web page, an attacker could bypass script filtering and perform
cross-site scripting attacks. (CVE-2008-4066)

Boris Zbarsky and Georgi Guninski independently discovered flaws in
the resource: protocol. An attacker could exploit this to perform
directory traversal, read information about the system, and prompt the
user to save information in a file. (CVE-2008-4067, CVE-2008-4068)

Georgi Guninski discovered that Thunderbird improperly handled
cancelled newsgroup messages. If a user opened a crafted newsgroup
message, an attacker could cause a buffer overrun and potentially
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2008-4070).

Solution :

Update the affected packages.
