| Description: | Summary:
The remote host is missing an update for the 'thunderbird' package(s) announced via the USN-782-1 advisory.
Vulnerability Insight:
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
machine-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)
