3. Description:
Mozilla Thunderbird is a standalone mail and newsgroup client.
Several flaws were found in the processing of malformed HTML content. An
HTML mail message containing malicious content could possibly lead to
arbitrary code execution with the privileges of the user running
Thunderbird. (CVE-2011-0080, CVE-2011-0081)
An arbitrary memory write flaw was found in the way Thunderbird handled
out-of-memory conditions. If all memory was consumed when a user viewed a
malicious HTML mail message, it could possibly lead to arbitrary code
execution with the privileges of the user running Thunderbird.
(CVE-2011-0078)
An integer overflow flaw was found in the way Thunderbird handled the HTML
frameset tag. An HTML mail message with a frameset tag containing large
values for the "rows" and "cols" attributes could trigger this flaw,
possibly leading to arbitrary code execution with the privileges of the
user running Thunderbird. (CVE-2011-0077)
A flaw was found in the way Thunderbird handled the HTML iframe tag. An
HTML mail message with an iframe tag containing a specially-crafted source
address could trigger this flaw, possibly leading to arbitrary code
execution with the privileges of the user running Thunderbird.
(CVE-2011-0075)
A flaw was found in the way Thunderbird displayed multiple marquee
elements. A malformed HTML mail message could cause Thunderbird to execute
arbitrary code with the privileges of the user running Thunderbird.
(CVE-2011-0074)
A flaw was found in the way Thunderbird handled the nsTreeSelection
element. Malformed content could cause Thunderbird to execute arbitrary
code with the privileges of the user running Thunderbird. (CVE-2011-0073)
A directory traversal flaw was found in the Thunderbird resource://
protocol handler. Malicious content could cause Thunderbird to access
arbitrary files accessible to the user running Thunderbird. (CVE-2011-0071)
A double free flaw was found in the way Thunderbird handled
"application/http-index-format" documents. A malformed HTTP response could
cause Thunderbird to execute arbitrary code with the privileges of the user
running Thunderbird. (CVE-2011-0070)
All Thunderbird users should upgrade to this updated package, which
resolves these issues. All running instances of Thunderbird must be
restarted for the update to take effect.
