1. Summary:

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

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Optional Productivity Applications (v. 5 server) - i386, x86_64

3. Problem description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the way Thunderbird processed certain malformed
JavaScript code. A malicious HTML mail message could execute JavaScript
code in such a way that may result in Thunderbird crashing or executing
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-2007-0775, CVE-2007-0777)

Several cross-site scripting (XSS) flaws were found in the way Thunderbird
processed certain malformed HTML mail messages. A malicious HTML mail
message could display misleading information which may result in a user
unknowingly divulging sensitive information such as a password.
(CVE-2006-6077, CVE-2007-0995, CVE-2007-0996)

A flaw was found in the way Thunderbird processed text/enhanced and
text/richtext formatted mail message. A specially crafted mail message
could execute arbitrary code with the privileges of the user running
Thunderbird. (CVE-2007-1282)

A flaw was found in the way Thunderbird cached web content on the local
disk. A malicious HTML mail message may be able to inject arbitrary HTML
into a browsing session if the user reloads a targeted site. (CVE-2007-0778)

A flaw was found in the way Thunderbird displayed certain web content. A
malicious HTML mail message could generate content which could overlay user
interface elements such as the hostname and security indicators, tricking a
user into thinking they are visiting a different site. (CVE-2007-0779)

Two flaws were found in the way Thunderbird displayed blocked popup
windows. If a user can be convinced to open a blocked popup, it is possible
to read arbitrary local files, or conduct an XSS attack against the user.
(CVE-2007-0780, CVE-2007-0800)

Two buffer overflow flaws were found in the Network Security Services (NSS)
code for processing the SSLv2 protocol. Connecting to a malicious secure
web server could cause the execution of arbitrary code as the user running
Thunderbird. (CVE-2007-0008, CVE-2007-0009)

A flaw was found in the way Thunderbird handled the "location.hostname"
value during certain browser domain checks. This flaw could allow a
malicious HTML mail message to set domain cookies for an arbitrary site, or
possibly perform an XSS attack. (CVE-2007-0981)

Users of Thunderbird are advised to apply this update, which contains
Thunderbird version 1.5.0.10 that corrects these issues.
