thunderbird security update

Type/Severity

Security Advisory: Critical

Topic

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

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

Description

Mozilla Thunderbird is a standalone mail and newsgroup client.

The Mozilla Foundation has discontinued support for the Mozilla Thunderbird
1.0 branch. This update deprecates the Mozilla Thunderbird 1.0 branch in
Red Hat Enterprise Linux 4 in favor of the supported Mozilla Thunderbird
1.5 branch.

This update also resolves a number of outstanding Thunderbird security issues:

Several flaws were found in the way Thunderbird processed certain
javascript actions. A malicious mail message could execute arbitrary
javascript instructions with the permissions of "chrome", allowing the page
to steal sensitive information or install browser malware. (CVE-2006-2776,
CVE-2006-2784, CVE-2006-2785, CVE-2006-2787, CVE-2006-3807, CVE-2006-3809)

Several denial of service flaws were found in the way Thunderbird processed
certain mail messages. A malicious web page could crash the browser or
possibly execute arbitrary code as the user running Thunderbird.
(CVE-2006-2779, CVE-2006-2780, CVE-2006-3801, CVE-2006-3677,
CVE-2006-3113, CVE-2006-3803, CVE-2006-3805, CVE-2006-3806, CVE-2006-3811)

Several flaws were found in the way Thunderbird processed certain
javascript actions. A malicious mail message could conduct a cross-site
scripting attack or steal sensitive information (such as cookies owned by
other domains). (CVE-2006-3802, CVE-2006-3810)

A form file upload flaw was found in the way Thunderbird handled javascript
input object mutation. A malicious mail message could upload an arbitrary
local file at form submission time without user interaction. (CVE-2006-2782)

A denial of service flaw was found in the way Thunderbird called the
crypto.signText() javascript function. A malicious mail message could crash
the browser if the victim had a client certificate loaded. (CVE-2006-2778)

A flaw was found in the way Thunderbird processed Proxy AutoConfig scripts.
A malicious Proxy AutoConfig server could execute arbitrary javascript
instructions with the permissions of "chrome", allowing the page to steal
sensitive information or install client malware. (CVE-2006-3808)

Note: Please note that JavaScript support is disabled by default in
Thunderbird. The above issues are not exploitable with JavaScript disabled.

Two flaws were found in the way Thunderbird displayed malformed inline
vcard attachments. If a victim viewed an email message containing a
carefully crafted vcard it was possible to execute arbitrary code as the
user running Thunderbird. (CVE-2006-2781, CVE-2006-3804)

A cross site scripting flaw was found in the way Thunderbird processed
Unicode Byte-order-Mark (BOM) markers in UTF-8 mail messages. A malicious
web page could execute a script within the browser that a web input
sanitizer could miss due to a malformed "script" tag. (CVE-2006-2783)

Two HTTP response smuggling flaws were found in the way Thunderbird
processed certain invalid HTTP response headers. A malicious web site could
return specially crafted HTTP response headers which may bypass HTTP proxy
restrictions. (CVE-2006-2786)

A double free flaw was found in the way the nsIX509::getRawDER method was
called. If a victim visited a carefully crafted web page, it was possible
to crash Thunderbird. (CVE-2006-2788)

Users of Thunderbird are advised to upgrade to this update, which contains
Thunderbird version 1.5.0.5 that corrects these issues.
