Justin Schuh, Tom Cross and Peter Williams discovered errors in the Firefox URL parsing routines. If a user were tricked into opening a crafted hyperlink, an attacker could overflow a stack buffer and execute arbitrary code. (CVE-2008-0016)

It was discovered that the same-origin check in Firefox could be bypassed. If a user were tricked into opening a malicious website, an attacker may be able to execute JavaScript in the context of a different website. (CVE-2008-3835)

Several problems were discovered in the JavaScript engine. This could allow an attacker to execute scripts from page content with chrome privileges. (CVE-2008-3836)

Paul Nickerson discovered Firefox did not properly process mouse click events. If a user were tricked into opening a malicious web page, an attacker could move the content window, which could potentially be used to force a user to perform unintended drag and drop operations.
(CVE-2008-3837)

Several problems were discovered in the browser engine. This could allow an attacker to execute code with chrome privileges.
(CVE-2008-4058, CVE-2008-4059, CVE-2008-4060)

Drew Yao, David Maciejak and other Mozilla developers found several problems in the browser engine of Firefox. If a user were tricked into opening a malicious web page, an attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-4061, CVE-2008-4062, CVE-2008-4063, CVE-2008-4064)

Dave Reed discovered a flaw in the JavaScript parsing code when processing certain BOM characters. An attacker could exploit this to bypass script filters and perform cross-site scripting attacks.
(CVE-2008-4065)

Gareth Heyes discovered a flaw in the HTML parser of Firefox. If a user were tricked into opening a malicious web page, an attacker could bypass script filtering and perform cross-site scripting attacks.
(CVE-2008-4066)

Boris Zbarsky and Georgi Guninski independently discovered flaws in the resource: protocol. An attacker could exploit this to perform directory traversal, read information about the system, and prompt the user to save information in a file. (CVE-2008-4067, CVE-2008-4068)

Billy Hoffman discovered a problem in the XBM decoder. If a user were tricked into opening a malicious web page or XBM file, an attacker may be able to cause a denial of service via application crash.
(CVE-2008-4069).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

From Red Hat Security Advisory 2008:0908 :

Updated thunderbird packages that fix several security issues 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 processing of 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. (CVE-2008-0016, CVE-2008-4058, CVE-2008-4059, CVE-2008-4060, CVE-2008-4061, CVE-2008-4062)

Several flaws were found in the way malformed HTML mail content was displayed. An HTML mail message containing specially crafted content could potentially trick a Thunderbird user into surrendering sensitive information. (CVE-2008-3835, CVE-2008-4067, CVE-2008-4068)

A flaw was found in Thunderbird that caused certain characters to be stripped from JavaScript code. This flaw could allow malicious JavaScript to bypass or evade script filters. (CVE-2008-4065, CVE-2008-4066)

Note: JavaScript support is disabled by default in Thunderbird; the above issue is not exploitable unless JavaScript is enabled.

A heap based buffer overflow flaw was found in the handling of cancelled newsgroup messages. If the user cancels a specially crafted newsgroup message it could cause Thunderbird to crash or, potentially, execute arbitrary code as the user running Thunderbird.
(CVE-2008-4070)

All Thunderbird users should upgrade to these updated packages, which resolve these issues.

This update brings Mozilla Thunderbird to version 2.0.0.17.

It contains the following security fixes: MFSA 2008-46 / CVE-2008-4070: Heap overflow when canceling a newsgroup message

MFSA 2008-44 / CVE-2008-4067 / CVE-2008-4068: resource: traversal vulnerabilities

MFSA 2008-43: BOM characters stripped from JavaScript before execution CVE-2008-4065: Stripped BOM characters bug CVE-2008-4066: HTML escaped low surrogates bug

MFSA 2008-42 Crashes with evidence of memory corruption (rv:1.9.0.2/1.8.1.17): CVE-2008-4061: Jesse Ruderman reported a crash in the layout engine. CVE-2008-4062: Igor Bukanov, Philip Taylor, Georgi Guninski, and Antoine Labour reported crashes in the JavaScript engine. CVE-2008-4063: Jesse Ruderman, Bob Clary, and Martijn Wargers reported crashes in the layout engine which only affected Firefox 3.
CVE-2008-4064: David Maciejak and Drew Yao reported crashes in graphics rendering which only affected Firefox 3.

MFSA 2008-41 Privilege escalation via XPCnativeWrapper pollution CVE-2008-4058: XPCnativeWrapper pollution bugs CVE-2008-4059:
XPCnativeWrapper pollution (Firefox 2) CVE-2008-4060: Documents without script handling objects

Updated SeaMonkey packages that fix a security issues are now available for Red Hat Enterprise Linux 2.1, Red Hat Enterprise Linux 3 and Red Hat Enterprise Linux 4.

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

SeaMonkey is an open source Web browser, advanced email and newsgroup client, IRC chat client, and HTML editor.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause SeaMonkey to crash or, potentially, execute arbitrary code as the user running SeaMonkey.
(CVE-2008-0016, CVE-2008-4058, CVE-2008-4059, CVE-2008-4060, CVE-2008-4061, CVE-2008-4062)

Several flaws were found in the way malformed web content was displayed. A web page containing specially crafted content could potentially trick a SeaMonkey user into surrendering sensitive information. (CVE-2008-3835, CVE-2008-4067, CVE-2008-4068, CVE-2008-4069)

A flaw was found in the way SeaMonkey handles mouse click events. A web page containing specially crafted JavaScript code could move the content window while a mouse-button was pressed, causing any item under the pointer to be dragged. This could, potentially, cause the user to perform an unsafe drag-and-drop action. (CVE-2008-3837)

A flaw was found in SeaMonkey that caused certain characters to be stripped from JavaScript code. This flaw could allow malicious JavaScript to bypass or evade script filters. (CVE-2008-4065, CVE-2008-4066)

All SeaMonkey users should upgrade to these updated packages, which contain backported patches to resolve these issues.
