[MFSA-2006-16]

  - CVE-2006-1734     'shutdown' discovered that it is possible to access an     internal function object which could then be used to run     arbitrary JavaScript code with full permissions of the     user running the browser, which could be used to install     spyware or viruses. [MFSA-2006-15]

  - CVE-2006-1790     A regression fix that could lead to memory corruption     allows remote attackers to cause a denial of service and     possibly execute arbitrary code. [MFSA-2006-11]

New updates are available for Mozilla Firefox :

A regression in the LE2005 Firefox package caused problems with cursor movement that has been fixed.

The run-mozilla.sh script, with debugging enabled, would allow local users to create or overwrite arbitrary files via a symlink attack on temporary files (CVE-2005-2353).

nsScriptSecurityManager::GetBaseURIScheme didn't handle jar:view-source:... correctly because the jar: and view-source: cases didn't use recursion as they were supposed to. This was corrected in Firefox 1.0.4 and only affects the LE2005 package.

The updated packages have been patched to correct these issues.

Updated Mozilla Thunderbird packages fix various vulnerabilities :

The run-mozilla.sh script, with debugging enabled, would allow local users to create or overwrite arbitrary files via a symlink attack on temporary files (CVE-2005-2353).

A bug in the way Thunderbird processes XBM images could be used to execute arbitrary code via a specially crafted XBM image file (CVE-2005-2701).

A bug in the way Thunderbird handles certain Unicode sequences could be used to execute arbitrary code via viewing a specially crafted Unicode sequence (CVE-2005-2702).

A bug in the way Thunderbird makes XMLHttp requests could be abused by a malicious web page to exploit other proxy or server flaws from the victim's machine; however, the default behaviour of the browser is to disallow this (CVE-2005-2703).

A bug in the way Thunderbird implemented its XBL interface could be abused by a malicious web page to create an XBL binding in such a way as to allow arbitrary JavaScript execution with chrome permissions (CVE-2005-2704).

An integer overflow in Thunderbird's JavaScript engine could be manipulated in certain conditions to allow a malicious web page to execute arbitrary code (CVE-2005-2705).

A bug in the way Thunderbird displays about: pages could be used to execute JavaScript with chrome privileges (CVE-2005-2706).

A bug in the way Thunderbird opens new windows could be used by a malicious web page to construct a new window without any user interface elements (such as address bar and status bar) that could be used to potentially mislead the user (CVE-2005-2707).

A bug in the way Thunderbird proceesed URLs on the command line could be used to execute arbitary commands as the user running Thunderbird;
this could be abused by clicking on a supplied link, such as from an instant messaging client (CVE-2005-2968).

Tom Ferris reported that Thunderbird would crash when processing a domain name consisting solely of soft-hyphen characters due to a heap overflow when IDN processing results in an empty string after removing non-wrapping chracters, such as soft-hyphens. This could be exploited to run or or install malware on the user's computer (CVE-2005-2871).

The updated packages have been patched to correct these issues.

Vladimir V. Perepelitsa discovered a bug in Thunderbird's handling of anonymous functions during regular expression string replacement. A malicious HTML email could exploit this to capture a random block of client memory. (CAN-2005-0989)

Georgi Guninski discovered that the types of certain XPInstall related JavaScript objects were not sufficiently validated when they were called. This could be exploited by malicious HTML email content to crash Thunderbird or even execute arbitrary code with the privileges of the user. (CAN-2005-1159) 

Thunderbird did not properly verify the values of XML DOM nodes. By tricking the user to perform a common action like clicking on a link or opening the context menu, a malicious HTML email could exploit this to execute arbitrary JavaScript code with the full privileges of the user. (CAN-2005-1160)

A variant of the attack described in CAN-2005-1160 (see USN-124-1) was discovered. Additional checks were added to make sure JavaScript eval and script objects are run with the privileges of the context that created them, not the potentially elevated privilege of the context calling them. (CAN-2005-1532)

Scripts in XBL controls from web content continued to be run even when JavaScript was disabled. This could be combined with most script-based exploits to attack people running vulnerable versions who thought disabling JavaScript would protect them. (CAN-2005-2261)

The function for version comparison in the addons installer did not properly verify the type of its argument. By passing specially crafted JavaScript objects to it, a malicious website could crash Thunderbird and possibly even execute arbitrary code with the privilege of the user account Thunderbird runs in. (CAN-2005-2265)

The XHTML DOM node handler did not take namespaces into account when verifying node types based on their names. For example, an XHTML email could contain an <IMG> tag with malicious contents, which would then be processed as the standard trusted HTML <img> tag. By tricking an user to view a malicious email, this could be exploited to execute attacker-specified code with the full privileges of the user.
(CAN-2005-2269) 

It was discovered that some objects were not created appropriately.
This allowed malicious web content scripts to trace back the creation chain until they found a privileged object and execute code with higher privileges than allowed by the current site. (CAN-2005-2270) 

Javier Fernandez-Sanguino Pena discovered that the run-mozilla.sh script created temporary files in an unsafe way when running with 'debugging' enabled. This could allow a symlink attack to create or overwrite arbitrary files with the privileges of the user invoking the program. (CAN-2005-2353)

The update for Ubuntu 4.10 (Warty Warthog) also fixes several less critical vulnerabilities which are not present in the Ubuntu 5.04 version. (MFSA-2005-02 to MFSA-2005-30; please see the following web site for details:
http://www.mozilla.org/projects/security/known-vulnerabilities.html).
We apologize for the huge delay of this update; we changed our update strategy for Mozilla products to make sure that such long delays will not happen again.

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.
