Updated firefox packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5.

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

Mozilla Firefox is an open source Web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code as the user running Firefox.
(CVE-2009-1392, CVE-2009-1832, CVE-2009-1833, CVE-2009-1837, CVE-2009-1838, CVE-2009-1841)

Multiple flaws were found in the processing of malformed, local file content. If a user loaded malicious, local content via the file:// URL, it was possible for that content to access other local data.
(CVE-2009-1835, CVE-2009-1839)

A script, privilege elevation flaw was found in the way Firefox loaded XML User Interface Language (XUL) scripts. Firefox and certain add-ons could load malicious content when certain policy checks did not happen. (CVE-2009-1840)

A flaw was found in the way Firefox displayed certain Unicode characters in International Domain Names (IDN). If an IDN contained invalid characters, they may have been displayed as spaces, making it appear to the user that they were visiting a trusted site.
(CVE-2009-1834)

A flaw was found in the way Firefox handled error responses returned from proxy servers. If an attacker is able to conduct a man-in-the-middle attack against a Firefox instance that is using a proxy server, they may be able to steal sensitive information from the site the user is visiting. (CVE-2009-1836)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.0.11. You can find a link to the Mozilla advisories in the References section of this errata.

All Firefox users should upgrade to these updated packages, which contain Firefox version 3.0.11, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

An updated thunderbird package that fixes several security issues is now available for Red Hat Enterprise Linux 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-2009-1392, CVE-2009-1303, CVE-2009-1305, CVE-2009-1833, CVE-2009-1838)

Several flaws were found in the way malformed HTML mail content was processed. An HTML mail message containing malicious content could execute arbitrary JavaScript in the context of the mail message, possibly presenting misleading data to the user, or stealing sensitive information such as login credentials. (CVE-2009-1306, CVE-2009-1307, CVE-2009-1308, CVE-2009-1309)

A flaw was found in the way Thunderbird handled error responses returned from proxy servers. If an attacker is able to conduct a man-in-the-middle attack against a Thunderbird instance that is using a proxy server, they may be able to steal sensitive information from the site Thunderbird is displaying. (CVE-2009-1836)

Note: JavaScript support is disabled by default in Thunderbird. None of the above issues are exploitable unless JavaScript is enabled.

All Thunderbird users should upgrade to this updated package, which resolves these issues. All running instances of Thunderbird must be restarted for the update to take effect.

seamonkey was updated to version 1.1.18, fixing various security issues :

MFSA 2009-43 / CVE-2009-2404 Moxie Marlinspike reported a heap overflow vulnerability in the code that handles regular expressions in certificate names. This vulnerability could be used to compromise the browser and run arbitrary code by presenting a specially crafted certificate to the client. This code provided compatibility with the non-standard regular expression syntax historically supported by Netscape clients and servers. With version 3.5 Firefox switched to the more limited industry-standard wildcard syntax instead and is not vulnerable to this flaw. 

MFSA 2009-42 / CVE-2009-2408: IOActive security researcher Dan Kaminsky reported a mismatch in the treatment of domain names in SSL certificates between SSL clients and the Certificate Authorities (CA) which issue server certificates. In particular, if a malicious person requested a certificate for a host name with an invalid null character in it most CAs would issue the certificate if the requester owned the domain specified after the null, while most SSL clients (browsers) ignored that part of the name and used the unvalidated part in front of the null. This made it possible for attackers to obtain certificates that would function for any site they wished to target.
These certificates could be used to intercept and potentially alter encrypted communication between the client and a server such as sensitive bank account transactions. This vulnerability was independently reported to us by researcher Moxie Marlinspike who also noted that since Firefox relies on SSL to protect the integrity of security updates this attack could be used to serve malicious updates.
Mozilla would like to thank Dan and the Microsoft Vulnerability Research team for coordinating a multiple-vendor response to this problem.

The update also contains the fixes from the skipped 1.1.17 security update: MFSA 2009-17/CVE-2009-1307: Same-origin violations when Adobe Flash loaded via view-source: scheme 

MFSA 2009-21/CVE-2009-1311:POST data sent to wrong site when saving web page with embedded frame 

MFSA 2009-24/CVE-2009-1392/CVE-2009-1832/CVE-2009-1833: Crashes with evidence of memory corruption (rv:1.9.0.11) 

MFSA 2009-26/CVE-2009-1835: Arbitrary domain cookie access by local file: resources 

MFSA 2009-27/CVE-2009-1836: SSL tampering via non-200 responses to proxy CONNECT requests 

MFSA 2009-29/CVE-2009-1838: Arbitrary code execution using event listeners attached to an element whose owner document is null 

MFSA 2009-32/CVE-2009-1841: JavaScript chrome privilege escalation MFSA 2009-33/CVE-2009-2210: Crash viewing multipart/alternative message with text/enhanced part

The installed version of Firefox is earlier than 3.0.11. Such versions are potentially affected by the following security issues :

  - Multiple memory corruption vulnerabilities could     potentially be exploited to execute arbitrary code.     (MFSA 2009-24)

  - Certain invalid Unicode characters, when used as a part     of IDN, can be displayed as a whitespace in the location     bar. An attacker could exploit this vulnerability to     spoof the location bar. (MFSA 2009-25)  

  - It may be possible for local resources loaded via     'file:' protocol to access any domain's cookies saved     on a user's system. (MFSA 2009-26)

  - It may be possible to tamper with SSL data via non-200     responses to proxy CONNECT requests. (MFSA 2009-27)

  - A race condition exists in 'NPObjWrapper_NewResolve'     when accessing the properties of a NPObject, a     wrapped JSObject. This flaw could be potentially     exploited to execute arbitrary code on the remote     system. (MFSA 2009-28)

  - If the owner document of an element becomes null after     garbage collection, then it may be possible to execute     the event listeners within the wrong JavaScript context.
    An attacker could potentially exploit this vulnerability     to execute arbitrary JavaScript with chrome privileges.
    (MFSA 2009-29)  

  - When the 'file:' resource is loaded from the location     bar, the resource inherits the principal of the     previously loaded document. This could potentially allow     unauthorized access to local files. (MFSA 2009-30)

  - While loading external scripts into XUL documents     content-loading policies are not checked.     (MFSA 2009-31)   

  - It may be possible for scripts from page content to     run with elevated privileges. (MFSA 2009-32)
