Description

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed HTML mail content.
An HTML mail message containing malicious content could cause Thunderbird
to crash or, potentially, execute arbitrary code with the privileges of the
user running Thunderbird. (CVE-2010-0174, CVE-2010-1200, CVE-2010-1211,
CVE-2010-1214, CVE-2010-2753)

An integer overflow flaw was found in the processing of malformed HTML mail
content. An HTML mail message containing malicious content could cause
Thunderbird to crash or, potentially, execute arbitrary code with the
privileges of the user running Thunderbird. (CVE-2010-1199)

Several use-after-free flaws were found in Thunderbird. Viewing an HTML
mail message containing malicious content could result in Thunderbird
executing arbitrary code with the privileges of the user running
Thunderbird. (CVE-2010-0175, CVE-2010-0176, CVE-2010-0177)

A flaw was found in the way Thunderbird plug-ins interact. It was possible
for a plug-in to reference the freed memory from a different plug-in,
resulting in the execution of arbitrary code with the privileges of the
user running Thunderbird. (CVE-2010-1198)

A flaw was found in the way Thunderbird handled the "Content-Disposition:
attachment" HTTP header when the "Content-Type: multipart" HTTP header was
also present. Loading remote HTTP content that allows arbitrary uploads and
relies on the "Content-Disposition: attachment" HTTP header to prevent
content from being displayed inline, could be used by an attacker to serve
malicious content to users. (CVE-2010-1197)

A same-origin policy bypass flaw was found in Thunderbird. Remote HTML
content could steal private data from different remote HTML content
Thunderbird has loaded. (CVE-2010-2754)

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.
