This update brings Mozilla SeaMonkey to the 2.0.6 security release.

It fixes following security bugs: MFSA 2010-34 / CVE-2010-1211:
Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products.
Some of these bugs 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. Jesse Ruderman, Ehsan Akhgari, Mats Palmgren, Igor Bukanov, Gary Kwong, Tobias Markus and Daniel Holbert reported memory safety problems that affected Firefox 3.6 and Firefox 3.5.

MFSA 2010-35 / CVE-2010-1208: Security researcher regenrecht reported via TippingPoint's Zero Day Initiative an error in the DOM attribute cloning routine where under certain circumstances an event attribute node can be deleted while another object still contains a reference to it. This reference could subsequently be accessed, potentially causing the execution of attacker controlled memory.

MFSA 2010-36 / CVE-2010-1209: Security researcher regenrecht reported via TippingPoint's Zero Day Initiative an error in Mozilla's implementation of NodeIterator in which a malicious NodeFilter could be created which would detach nodes from the DOM tree while it was being traversed. The use of a detached and subsequently deleted node could result in the execution of attacker-controlled memory.

MFSA 2010-37 / CVE-2010-1214: Security researcher J23 reported via TippingPoint's Zero Day Initiative an error in the code used to store the names and values of plugin parameter elements. A malicious page could embed plugin content containing a very large number of parameter elements which would cause an overflow in the integer value counting them. This integer is later used in allocating a memory buffer used to store the plugin parameters. Under such conditions, too small a buffer would be created and attacker-controlled data could be written past the end of the buffer, potentially resulting in code execution.

MFSA 2010-39 / CVE-2010-2752: Security researcher J23 reported via TippingPoint's Zero Day Initiative that an array class used to store CSS values contained an integer overflow vulnerability. The 16 bit integer value used in allocating the size of the array could overflow, resulting in too small a memory buffer being created. When the array was later populated with CSS values data would be written past the end of the buffer potentially resulting in the execution of attacker-controlled memory.

MFSA 2010-40 / CVE-2010-2753: Security researcher regenrecht reported via TippingPoint's Zero Day Initiative an integer overflow vulnerability in the implementation of the XUL <tree> element's selection attribute. When the size of a new selection is sufficiently large the integer used in calculating the length of the selection can overflow, resulting in a bogus range being marked selected. When adjustSelection is then called on the bogus range the range is deleted leaving dangling references to the ranges which could be used by an attacker to call into deleted memory and run arbitrary code on a victim's computer.

MFSA 2010-41 / CVE-2010-1205: OUSPG researcher Aki Helin reported a buffer overflow in Mozilla graphics code which consumes image data processed by libpng. A malformed PNG file could be created which would cause libpng to incorrectly report the size of the image to downstream consumers. When the dimensions of such images are underreported, the Mozilla code responsible for displaying the graphic will allocate too small a memory buffer to contain the image data and will wind up writing data past the end of the buffer. This could result in the execution of attacker-controlled memory.

MFSA 2011-42 / CVE-2010-1213: Security researcher Yosuke Hasegawa reported that the Web Worker method importScripts can read and parse resources from other domains even when the content is not valid JavaScript. This is a violation of the same-origin policy and could be used by an attacker to steal information from other sites.

MFSA 2010-45 / CVE-2010-1206: Google security researcher Michal Zalewski reported two methods for spoofing the contents of the location bar. The first method works by opening a new window containing a resource that responds with an HTTP 204 (no content) and then using the reference to the new window to insert HTML content into the blank document. The second location bar spoofing method does not require that the resource opened in a new window respond with 204, as long as the opener calls window.stop() before the document is loaded.
In either case a user could be mislead as to the correct location of the document they are currently viewing.

MFSA 2010-45 / CVE-2010-2751: Security researcher Jordi Chancel reported that the location bar could be spoofed to look like a secure page when the current document was served via plaintext. The vulnerability is triggered by a server by first redirecting a request for a plaintext resource to another resource behind a valid SSL/TLS certificate. A second request made to the original plaintext resource which is responded to not with a redirect but with JavaScript containing history.back() and history.forward() will result in the plaintext resource being displayed with valid SSL/TLS badging in the location bar.

MFSA 2010-46 / CVE-2010-0654: Google security researcher Chris Evans reported that data can be read across domains by injecting bogus CSS selectors into a target site and then retrieving the data using JavaScript APIs. If an attacker can inject opening and closing portions of a CSS selector into points A and B of a target page, then the region between the two injection points becomes readable to JavaScript through, for example, the getComputedStyle() API.

MFSA 2010-47 / CVE-2010-2754: Security researcher Soroush Dalili reported that potentially sensitive URL parameters could be leaked across domains upon script errors when the script filename and line number is included in the error message.

From Red Hat Security Advisory 2010:0546 :

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 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-2010-1211, CVE-2010-2753, CVE-2010-1214)

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

A same-origin policy bypass flaw was found in SeaMonkey. An attacker could create a malicious web page that, when viewed by a victim, could steal private data from a different website the victim has loaded with SeaMonkey. (CVE-2010-2754)

A flaw was found in the way SeaMonkey displayed the location bar when visiting a secure web page. A malicious server could use this flaw to present data that appears to originate from a secure server, even though it does not. (CVE-2010-2751)

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.

The installed version of Thunderbird is earlier than 3.0.6.  Such versions are potentially affected by the following security issues :

  - Multiple memory safety bugs could result in memory     corruption, potentially resulting in arbitrary code     execution. (MFSA 2010-34)

 - The array class used to store CSS values is affected     by an integer overflow vulnerability. (MFSA 2010-39)

  - An integer overflow vulnerability exists in the     'selection' attribute of XUL <tree> element.
    (MFSA 2010-40)

  - A buffer overflow vulnerability in Mozilla graphics     code could lead to arbitrary code execution.
    (MFSA 2010-41)

  - It is possible to read and parse resources from other     domains even when the content is not valid JavaScript     leading to cross-domain data disclosure. (MFSA 2010-42)

  - It is possible to read data across domains by     injecting bogus CSS selectors into a target site.
    (MFSA 2010-46)

  - Potentially sensitive URL parameters could be leaked     across domains via script errors. (MFSA 2010-47)

Update to new upstream SeaMonkey version 2.0.6, fixing multiple security issues detailed in the upstream advisories:
http://www.mozilla.org/security/known- vulnerabilities/seamonkey20.html#seamonkey2.0.6

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.
