RHSA-2007:0981 - Security Advisory

Synopsis

Moderate: thunderbird security update

Type/Severity

Security Advisory: Moderate

Topic

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.

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.
