Details
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)
