Updated SeaMonkey packages that fix several security issues are now available for Red Hat Enterprise Linux 3 and 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, 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-2009-1392, CVE-2009-1833, CVE-2009-1838, CVE-2009-1841)

A flaw was 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)

All SeaMonkey users should upgrade to these updated packages, which correct these issues. After installing the update, SeaMonkey must be restarted for the changes to take effect.

Update to new upstream Firefox version 3.0.11, fixing multiple security issues detailed in the upstream advisories:
http://www.mozilla.org/security/known- vulnerabilities/firefox30.html#firefox3.0.11 Update also includes all packages depending on gecko-libs rebuild against new version of Firefox / XULRunner.

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

The installed version of SeaMonkey is earlier than 1.1.17.  Such versions are potentially affected by the following security issues :

  - When an Adobe Flash file is loaded via the     'view-source:' scheme, the Flash plugin misinterprets     the origin of the content as localhost. An attacker can     leverage this to launch cross-site request forger     attacks. It is also possible to exploit this to place     cookie-like objects on victim's computers.
    (MFSA 2009-17)

  - An information disclosure vulnerability exists when     saving the inner frame of a web page as a file when the     outer page has POST data associated with it.
    (MFSA 2009-21)

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

  - 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)

  - 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 can potentially exploit this vulnerability     to execute arbitrary JavaScript with chrome privileges.
    (MFSA 2009-29)

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

  - It may be possible to crash SeaMonkey while viewing     'multipart/alternative' mail message with a     'text/enhanced' part. (MFSA 2009-33)

This update brings the Mozilla SeaMonkey Suite packages to the current stable release 1.1.17.

Due to the major version update some incompatibilities might appear.

It fixes all currently published security issues, including but not limited to :

  - Same-origin violations when Adobe Flash loaded via     view-source: scheme. (MFSA 2009-17 / CVE-2009-1307)

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

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

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

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

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

  - JavaScript chrome privilege escalation. (MFSA 2009-32 /     CVE-2009-1841)

  - Crash viewing multipart/alternative message with     text/enhanced part. (MFSA 2009-33 / CVE-2009-2210)

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
