Mozilla Firefox was updated to version 3.5.9 fixing lots of bugs and security issues.

The following security issues were fixed :

  - Mozilla developers identified and fixed several     stability bugs in the browser engine used in Firefox and     other Mozilla-based products. Some of these crashes     showed evidence of memory corruption under certain     circumstances, and we presume that with enough effort at     least some of these could be exploited to run arbitrary     code. (MFSA 2010-16)

Martijn Wargers, Josh Soref, and Jesse Ruderman reported crashes in the browser engine that affected Firefox 3.5 and Firefox 3.6.
(CVE-2010-0173)

Jesse Ruderman and Ehsan Akhgari reported crashes that affected all supported versions of the browser engine. (CVE-2010-0174)

  - Security researcher regenrecht reported via     TippingPoint's Zero Day Initiative that a select event     handler for XUL tree items could be called after the     tree item was deleted. This results in the execution of     previously freed memory which an attacker could use to     crash a victim's browser and run arbitrary code on the     victim's computer. (MFSA 2010-17 / CVE-2010-0175)

  - Security researcher regenrecht reported via     TippingPoint's Zero Day Initiative an error in the way     elements are inserted into a XUL tree optgroup. In     certain cases, the number of references to an element is     under-counted so that when the element is deleted, a     live pointer to its old location is kept around and may     later be used. An attacker could potentially use these     conditions to run arbitrary code on a victim's computer.
    (MFSA 2010-18 / CVE-2010-0176)

  - Security researcher regenrecht reported via     TippingPoint's Zero Day Initiative an error in the     implementation of the window.navigator.plugins object.
    When a page reloads, the plugins array would reallocate     all of its members without checking for existing     references to each member. This could result in the     deletion of objects for which valid pointers still     exist. An attacker could use this vulnerability to crash     a victim's browser and run arbitrary code on the     victim's machine. (MFSA 2010-19 / CVE-2010-0177)

  - Security researcher Paul Stone reported that a browser     applet could be used to turn a simple mouse click into a     drag-and-drop action, potentially resulting in the     unintended loading of resources in a user's browser.
    This behavior could be used twice in succession to first     load a privileged chrome: URL in a victim's browser,     then load a malicious javascript: URL on top of the same     document resulting in arbitrary script execution with     chrome privileges. (MFSA 2010-20 / CVE-2010-0178)

  - Mozilla security researcher moz_bug_r_a4 reported that     the XMLHttpRequestSpy module in the Firebug add-on was     exposing an underlying chrome privilege escalation     vulnerability. When the XMLHttpRequestSpy object was     created, it would attach various properties of itself to     objects defined in web content, which were not being     properly wrapped to prevent their exposure to chrome     privileged objects. This could result in an attacker     running arbitrary JavaScript on a victim's machine,     though it required the victim to have Firebug installed,     so the overall severity of the issue was determined to     be High. (MFSA 2010-21 / CVE-2010-0179)

  - Mozilla developers added support in the Network Security     Services module for preventing a type of     man-in-the-middle attack against TLS using forced     renegotiation. (MFSA 2010-22 / CVE-2009-3555)

Note that to benefit from the fix, Firefox 3.6 and Firefox 3.5 users will need to set their security.ssl.require_safe_negotiation preference to true. Firefox 3 does not contain the fix for this issue.

  - phpBB developer Henry Sudhof reported that when an image     tag points to a resource that redirects to a mailto:
    URL, the external mail handler application is launched.
    This issue poses no security threat to users but could     create an annoyance when browsing a site that allows     users to post arbitrary images. (MFSA 2010-23 /     CVE-2010-0181)

  - Mozilla community member Wladimir Palant reported that     XML documents were failing to call certain security     checks when loading new content. This could result in     certain resources being loaded that would otherwise     violate security policies set by the browser or     installed add-ons. (MFSA 2010-24 / CVE-2010-0182)

From Red Hat Security Advisory 2010:0333 :

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

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

Several use-after-free flaws were found in SeaMonkey. Visiting a web page containing malicious content could result in SeaMonkey executing arbitrary code with the privileges of the user running SeaMonkey.
(CVE-2010-0175, CVE-2010-0176, CVE-2010-0177)

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 with the privileges of the user running SeaMonkey. (CVE-2010-0174)

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.

A memory corruption flaw was found in the way Thunderbird decoded certain PNG images. An attacker could create a mail message containing a specially crafted PNG image that, when opened, could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2010-1205)

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 with the privileges of the user running Thunderbird. (CVE-2010-0174, CVE-2010-1200, CVE-2010-1211, CVE-2010-1214, CVE-2010-2753)

An integer overflow flaw was 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 with the privileges of the user running Thunderbird. (CVE-2010-1199)

Several use-after-free flaws were found in Thunderbird. Viewing an HTML mail message containing malicious content could result in Thunderbird executing arbitrary code with the privileges of the user running Thunderbird. (CVE-2010-0175, CVE-2010-0176, CVE-2010-0177)

A flaw was found in the way Thunderbird plug-ins interact. It was possible for a plug-in to reference the freed memory from a different plug-in, resulting in the execution of arbitrary code with the privileges of the user running Thunderbird. (CVE-2010-1198)

A flaw was found in the way Thunderbird handled the 'Content-Disposition: attachment' HTTP header when the 'Content-Type:
multipart' HTTP header was also present. Loading remote HTTP content that allows arbitrary uploads and relies on the 'Content-Disposition:
attachment' HTTP header to prevent content from being displayed inline, could be used by an attacker to serve malicious content to users. (CVE-2010-1197)

A same-origin policy bypass flaw was found in Thunderbird. Remote HTML content could steal private data from different remote HTML content Thunderbird has loaded. (CVE-2010-2754)

All running instances of Thunderbird must be restarted for the update to take effect.
