| Description: | Mozilla Thunderbird is a standalone mail and newsgroup client.
Several flaws were found in the way in which Thunderbird processed certain malformed HTML mail content. An HTML mail message containing malicious content could cause Thunderbird to crash or potentially execute arbitrary code as the user running Thunderbird. JavaScript support is disabled by default in Thunderbird; these issues are not exploitable unless the user has enabled JavaScript. (CVE-2007-5338, CVE-2007-5339, CVE-2007-5340)
Several flaws were found in the way in which Thunderbird displayed malformed HTML mail content. An HTML mail message containing specially-crafted content could potentially trick a user into surrendering sensitive information. (CVE-2007-1095, CVE-2007-3844, CVE-2007-3511, CVE-2007-5334)
A flaw was found in the Thunderbird sftp protocol handler. A malicious HTML mail message could access data from a remote sftp site, possibly stealing sensitive user data. (CVE-2007-5337)
A request-splitting flaw was found in the way in which Thunderbird generates a digest authentication request. If a user opened a specially-crafted URL, it was possible to perform cross-site scripting attacks, web cache poisoning, or other, similar exploits. (CVE-2007-2292)
Users of Thunderbird are advised to upgrade to these erratum packages, which contain backported patches that correct these issues.
