RHEL 4 / 5 : thunderbird (RHSA-2007:0981)

Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated thunderbird packages that fix several security bugs are now
available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

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,

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.

Users of Thunderbird are advised to upgrade to these erratum packages,
which contain backported patches that correct these issues.
