The remote version of Mozilla Thunderbird suffers from various security issues, some of which could lead to execution of arbitrary code on the affected host subject to the user's privileges.

This updates fixes several security problems in the Mozilla Firefox 1.5 browser and brings it up to 1.5.0.4 bugfix level. The full list is at:
http://www.mozilla.org/projects/security/known-vulnerabilities.html#fi refox1.5.0.4 MFSA 2006-31/CVE-2006-2787: EvalInSandbox allows remote attackers to gain privileges via JavaScript that calls the valueOf method on objects that were created outside of the sandbox. MFSA 2006-32/CVE-2006-2780: An Integer overflow allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via 'jsstr tagify,' which leads to memory corruption. MFSA 2006-32/CVE-2006-2779: Firefox allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) nested <option> tags in a select tag, (2) a DOMNodeRemoved mutation event, (3) 'Content-implemented tree views,' (4) BoxObjects, (5) the XBL implementation, (6) an iframe that attempts to remove itself, which leads to memory corruption. MFSA 2006-33/CVE-2006-2786: HTTP response smuggling vulnerability in Mozilla Firefox, when used with certain proxy servers, allows remote attackers to cause Firefox to interpret certain responses as if they were responses from two different sites via (1) invalid HTTP response headers with spaces between the header name and the colon, which might not be ignored in some cases, or (2) HTTP 1.1 headers through an HTTP 1.0 proxy, which are ignored by the proxy but processed by the client. MFSA 2006-34/CVE-2006-2785: Cross-site scripting (XSS) vulnerability in Mozilla Firefox allows user-complicit remote attackers to inject arbitrary web script or HTML by tricking a user into (1) performing a 'View Image' on a broken image in which the SRC attribute contains a JavaScript URL, or (2) selecting 'Show only this frame' on a frame whose SRC attribute contains a JavaScript URL. MFSA 2006-35/CVE-2006-2775: Mozilla Firefox associates XUL attributes with the wrong URL under certain unspecified circumstances, which might allow remote attackers to bypass restrictions by causing a persisted string to be associated with the wrong URL. MFSA 2006-36/CVE-2006-2784: The PLUGINSPAGE functionality in Mozilla Firefox allows remote user-complicit attackers to execute privileged code by tricking a user into installing missing plugins and selecting the 'Manual Install' button, then using nested javascript: URLs. MFSA 2006-37/CVE-2006-2776: Certain privileged UI code in Mozilla Firefox calls content-defined setters on an object prototype, which allows remote attackers to execute code at a higher privilege than intended.
MFSA 2006-38/CVE-2006-2778: The crypto.signText function in Mozilla Firefox allows remote attackers to execute arbitrary code via certain optional Certificate Authority name arguments, which causes an invalid array index and triggers a buffer overflow. MFSA 2006-39/CVE-2006-1942: Mozilla Firefox allows user-complicit remote attackers to open local files via a web page with an IMG element containing a SRC attribute with a non-image file:// URL, then tricking the user into selecting View Image for the broken image, as demonstrated using a ,wma file to launch Windows Media Player, or by referencing an 'alternate web page.' MFSA-2006-41/CVE-2006-2782:
Firefox does not fix all test cases associated with CVE-2006-1729, which allows remote attackers to read arbitrary files by inserting the target filename into a text box, then turning that box into a file upload control. MFSA 2006-42/CVE-2006-2783: Mozilla Firefox strips the Unicode Byte-order-Mark (BOM) from a UTF-8 page before the page is passed to the parser, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a BOM sequence in the middle of a dangerous tag such as SCRIPT. MFSA 2006-43/CVE-2006-2777:
Unspecified vulnerability in Mozilla Firefox allows remote attackers to execute arbitrary code by using the nsISelectionPrivate interface of the Selection object to add a SelectionListener and create notifications that are executed in a privileged context.

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.

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 website 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.

From Red Hat Security Advisory 2006:0735 :

Several flaws were found in the way Thunderbird processes certain malformed Javascript code.  A malicious HTML mail message could cause the execution of Javascript code in such a way that could cause Thunderbird to crash or execute arbitrary code as the user running Thunderbird.  (CVE-2006-5463, CVE-2006-5747, CVE-2006-5748)

Several flaws were found in the way Thunderbird renders HTML mail messages.  A malicious HTML mail message could cause the mail client to crash or possibly execute arbitrary code as the user running Thunderbird.  (CVE-2006-5464)

A flaw was found in the way Thunderbird verifies RSA signatures.  For RSA keys with exponent 3 it is possible for an attacker to forge a signature that would be incorrectly verified by the NSS library. Thunderbird as shipped trusts several root Certificate Authorities that use exponent 3.  An attacker could have created a carefully crafted SSL certificate which would be incorrectly trusted when their site was visited by a victim.  This flaw was previously thought to be fixed in Thunderbird 1.5.0.7, however Ulrich Kuehn discovered the fix was incomplete (CVE-2006-5462)


From Red Hat Security Advisory 2006:0677 :

Two flaws were found in the way Thunderbird processed certain regular expressions.  A malicious HTML email could cause a crash or possibly execute arbitrary code as the user running Thunderbird.  (CVE-2006-4565, CVE-2006-4566)

A flaw was found in the Thunderbird auto-update verification system.  An attacker who has the ability to spoof a victim's DNS could get Firefox to download and install malicious code.  In order to exploit this issue an attacker would also need to get a victim to previously accept an unverifiable certificate.  (CVE-2006-4567)

A flaw was found in the handling of Javascript timed events.  A malicious HTML email could crash the browser or possibly execute arbitrary code as the user running Thunderbird.  (CVE-2006-4253)

Daniel Bleichenbacher recently described an implementation error in RSA signature verification.  For RSA keys with exponent 3 it is possible for an attacker to forge a signature that which would be incorrectly verified by the NSS library.  (CVE-2006-4340)

A flaw was found in Thunderbird that triggered when a HTML message contained a remote image pointing to a XBL script.  An attacker could have created a carefully crafted message which would execute Javascript if certain actions were performed on the email by the recipient, even if Javascript was disabled.  (CVE-2006-4570)

A number of flaws were found in Thunderbird.  A malicious HTML email could cause a crash or possibly execute arbitrary code as the user running Thunderbird.  (CVE-2006-4571)
