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-2009-1303, CVE-2009-1305)

Several flaws were found in the way malformed web content was processed. A web page containing malicious content could execute arbitrary JavaScript in the context of the site, possibly presenting misleading data to a user, or stealing sensitive information such as login credentials. (CVE-2009-0652, CVE-2009-1306, CVE-2009-1307, CVE-2009-1309, CVE-2009-1312)

A flaw was found in the way SeaMonkey saved certain web pages to a local file. If a user saved the inner frame of a web page containing POST data, the POST data could be revealed to the inner frame, possibly surrendering sensitive information such as login credentials.
(CVE-2009-1311)

SeaMonkey must be restarted for the changes 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 remote Redhat Enterprise Linux 4 / 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2009:0436 advisory.

    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.

A     web page containing malicious content could execute arbitrary JavaScript in     the context of the site, possibly presenting misleading data to a user, or     stealing sensitive information such as login credentials.

    For technical details regarding these flaws, refer to the Mozilla security     advisories for Firefox 3.0.9. 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 3.0.9, which corrects these issues. After installing the     update, Firefox must be restarted for the changes to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated SeaMonkey packages that fix several security issues are now available for Red Hat Enterprise Linux 2.1, 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.

The installed version of Firefox is earlier than 3.0.9. Such versions are potentially affected by the following security issues :

  - Multiple remote memory corruption vulnerabilities exist     that can be exploited to execute arbitrary code in the     context of the user running the affected application.
    (MFSA 2009-14)

  - A flaw may exist where Unicode box drawing characters     are allowed in Internationalized Domain Names where they     could be visually confused with punctuation used in     valid web addresses. An attacker can leverage this to     launch a phishing-type scam against a victim.     (MFSA 2009-15)

  - A vulnerability exists when the 'jar:' scheme is used to     wrap a URI which serves the content with     'Content-Disposition: attachment'. An attacker can     leverage this to subvert sites that use this mechanism     to mitigate content injection attacks. (MFSA 2009-16)   
  - 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 forgery     attacks. It is also possible to exploit this to place     cookie-like objects on victim's computers.
    (MFSA 2009-17)

  - A vulnerability exists that allows attackers to inject     arbitrary scripts into sites via XBL bindings. This     vulnerability requires the attacker to have the ability     to embed third-party stylesheets into the site.     (MFSA 2009-18)

  - Multiple remote code execution vulnerabilities exist     caused by the creation of documents whose URI does not     match the document's principle using XMLHttpRequest, as     well as a flaw in the 'XPCNativeWrapper.ToString'     '__proto__' coming from the wrong scope. (MFSA 2009-19)

  - A malicious MozSearch plugin could be created using a     javascript: URI in the SearchForm value. An attacker can     leverage this in order to inject code into arbitrary     sites. (MFSA 2009-20)

  - 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)

  - A cross-site scripting vulnerability exists when     handling a Refresh header containing a javascript: URI.
    (MFSA 2009-22)

New seamonkey packages are available for Slackware 11.0, 12.0, 12.1, 12.2, and -current to fix security issues.
