The installed version of SeaMonkey is earlier than 2.8.0.  Such versions are potentially affected by the following security issues :
  - Multiple memory corruption issues. By tricking a user     into visiting a specially crafted page, these issues may     allow an attacker to execute arbitrary code in the     context of the affected application. (CVE-2012-0454,     CVE-2012-0457, CVE-2012-0459, CVE-2012-0461,     CVE-2012-0462, CVE-2012-0463, CVE-2012-0464)

  - An HTTP Header security bypass vulnerability that can be     leveraged by attackers to bypass certain security     restrictions and conduct cross-site scripting attacks.     (CVE-2012-0451).

  - A security bypass vulnerability that can be exploited by     an attacker if the victim can be tricked into setting a     new home page by dragging a specially crafted link to     the 'home' button URL, which will set the user's home     page to a 'javascript:' URL. (CVE-2012-0458) 

  - An information disclosure vulnerability due to an out of     bounds read in SVG filters. (CVE-2012-0456)

  - A cross-site scripting vulnerability that can be     triggered by dragging and dropping 'javascript:' links     onto a frame. (CVE-2012-0455)

  - 'window.fullScreen' is writeable by untrusted content,     allowing attackers to perform UI spoofing attacks.     (CVE-2012-0460)

The installed version of Firefox 3.6.x is potentially affected by the following security issues :
  - Multiple memory corruption issues. By tricking a user     into visiting a specially crafted page, these issues may     allow an attacker to execute arbitrary code in the     context of the affected application. (CVE-2012-0457,     CVE-2012-0461, CVE-2012-0463, CVE-2012-0464)

  - A security bypass vulnerability that can be exploited by     an attacker if the victim can be tricked into setting a     new home page by dragging a specially crafted link to     the 'home' button URL, which will set the user's home     page to a 'javascript:' URL. (CVE-2012-0458) 

  - An information disclosure vulnerability exists due to an     out of bounds read in SVG filters. (CVE-2012-0456)

  - A cross-site scripting vulnerability exists that can be     triggered by dragging and dropping 'javascript:' links     onto a frame. (CVE-2012-0455)

Security issues were identified and fixed in mozilla firefox and thunderbird :

Security researchers Blair Strang and Scott Bell of Security Assessment found that when a parent window spawns and closes a child window that uses the file open dialog, a crash can be induced in shlwapi.dll on 32-bit Windows 7 systems. This crash may be potentially exploitable (CVE-2012-0454).

Firefox prevents the dropping of javascript: links onto a frame to prevent malicious sites from tricking users into performing a cross-site scripting (XSS) attacks on themselves. Security researcher Soroush Dalili reported a way to bypass this protection (CVE-2012-0455).

Security researcher Atte Kettunen from OUSPG found two issues with Firefox's handling of SVG using the Address Sanitizer tool. The first issue, critically rated, is a use-after-free in SVG animation that could potentially lead to arbitrary code execution. The second issue is rated moderate and is an out of bounds read in SVG Filters. This could potentially incorporate data from the user's memory, making it accessible to the page content (CVE-2012-0457, CVE-2012-0456).

Security Researcher Mike Brooks of Sitewatch reported that if multiple Content Security Policy (CSP) headers are present on a page, they have an additive effect page policy. Using carriage return line feed (CRLF) injection, a new CSP rule can be introduced which allows for cross-site scripting (XSS) on sites with a separate header injection vulnerability (CVE-2012-0451).

Security researcher Mariusz Mlynski reported that an attacker able to convince a potential victim to set a new home page by dragging a link to the home button can set that user's home page to a javascript: URL.
Once this is done the attacker's page can cause repeated crashes of the browser, eventually getting the script URL loaded in the privileged about:sessionrestore context (CVE-2012-0458).

Mozilla community member Daniel Glazman of Disruptive Innovations reported a crash when accessing a keyframe's cssText after dynamic modification. This crash may be potentially exploitable (CVE-2012-0459).

Mozilla developer Matt Brubeck reported that window.fullScreen is writeable by untrusted content now that the DOM fullscreen API is enabled. Because window.fullScreen does not include mozRequestFullscreen's security protections, it could be used for UI spoofing. This code change makes window.fullScreen read only by untrusted content, forcing the use of the DOM fullscreen API in normal usage (CVE-2012-0460).

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 (CVE-2012-0461, CVE-2012-0462, CVE-2012-0464).

The mozilla firefox and thunderbird packages has been upgraded to the latest respective versions which is unaffected by these security flaws.

Additionally the NSS and NSPR packages has been upgraded to the latest versions. The OpenJDK java plugin (icedtea-web) has been upgraded to the 1.1.5 version whish bas better support for firefox 10.x+.

Update :

Updated packages for 2010.2 is being provided, despite the Mandriva products lifetime policy dictates otherwise.

USN-1400-1 fixed vulnerabilities in Firefox. Firefox 11 started using GSettings to access the system proxy settings. If there is a GSettings proxy settings schema, Firefox will consume it. The GSettings proxy settings schema that was shipped by default was unused by other applications and broke Firefox's ability to use system proxy settings.
This update removes the unused schema. We apologize for the inconvenience.

Soroush Dalili discovered that Firefox did not adequately protect against dropping JavaScript links onto a frame. A remote attacker could, through cross-site scripting (XSS), exploit this to modify the contents or steal confidential data. (CVE-2012-0455)

Atte Kettunen discovered a use-after-free vulnerability in Firefox's handling of SVG animations. An attacker could potentially exploit this to execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2012-0457)

Atte Kettunen discovered an out of bounds read vulnerability in Firefox's handling of SVG Filters. An attacker could potentially exploit this to make data from the user's memory accessible to the page content. (CVE-2012-0456)

Mike Brooks discovered that using carriage return line feed (CRLF) injection, one could introduce a new Content Security Policy (CSP) rule which allows for cross-site scripting (XSS) on sites with a separate header injection vulnerability. With cross-site scripting vulnerabilities, if a user were tricked into viewing a specially crafted page, a remote attacker could exploit this to modify the contents, or steal confidential data, within the same domain.
(CVE-2012-0451)

Mariusz Mlynski discovered that the Home button accepted JavaScript links to set the browser Home page. An attacker could use this vulnerability to get the script URL loaded in the privileged about:sessionrestore context. (CVE-2012-0458)

Daniel Glazman discovered that the Cascading Style Sheets (CSS) implementation is vulnerable to crashing due to modification of a keyframe followed by access to the cssText of the keyframe. If the user were tricked into opening a specially crafted web page, an attacker could exploit this to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-0459)

Matt Brubeck discovered that Firefox did not properly restrict access to the window.fullScreen object. If the user were tricked into opening a specially crafted web page, an attacker could potentially use this vulnerability to spoof the user interface. (CVE-2012-0460)

Bob Clary, Christian Holler, Jesse Ruderman, Michael Bebenita, David Anderson, Jeff Walden, Vincenzo Iozzo, and Willem Pinckaers discovered memory safety issues affecting Firefox. If the user were tricked into opening a specially crafted page, an attacker could exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. (CVE-2012-0461, CVE-2012-0462, CVE-2012-0464).

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

Mozilla Firefox is an open source web browser.

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 with the privileges of the user running Firefox. (CVE-2012-0461, CVE-2012-0462, CVE-2012-0464)

Two flaws were found in the way Firefox parsed certain Scalable Vector Graphics (SVG) image files. A web page containing a malicious SVG image file could cause an information leak, or cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2012-0456, CVE-2012-0457)

A flaw could allow a malicious site to bypass intended restrictions, possibly leading to a cross-site scripting (XSS) attack if a user were tricked into dropping a 'javascript:' link onto a frame.
(CVE-2012-0455)

It was found that the home page could be set to a 'javascript:' link.
If a user were tricked into setting such a home page by dragging a link to the home button, it could cause Firefox to repeatedly crash, eventually leading to arbitrary code execution with the privileges of the user running Firefox. (CVE-2012-0458)

A flaw was found in the way Firefox parsed certain web content containing 'cssText'. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2012-0459)

It was found that by using the DOM fullscreen API, untrusted content could bypass the mozRequestFullscreen security protections. A web page containing malicious web content could exploit this API flaw to cause user interface spoofing. (CVE-2012-0460)

A flaw was found in the way Firefox handled pages with multiple Content Security Policy (CSP) headers. This could lead to a cross-site scripting attack if used in conjunction with a website that has a header injection flaw. (CVE-2012-0451)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 10.0.3 ESR. You can find a link to the Mozilla advisories in the References section of this erratum.

This update also fixes the following bugs :

  - When using the Traditional Chinese locale (zh-TW), a     segmentation fault sometimes occurred when closing     Firefox.

  - Inputting any text in the Web Console (Tools -> Web     Developer -> Web Console) caused Firefox to crash.

All Firefox users should upgrade to these updated packages, which contain Firefox version 10.0.3 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed content.
Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2012-0461, CVE-2012-0462, CVE-2012-0464)

Two flaws were found in the way Thunderbird parsed certain Scalable Vector Graphics (SVG) image files. An HTML mail message containing a malicious SVG image file could cause an information leak, or cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2012-0456, CVE-2012-0457)

A flaw could allow malicious content to bypass intended restrictions, possibly leading to a cross-site scripting (XSS) attack if a user were tricked into dropping a 'javascript:' link onto a frame.
(CVE-2012-0455)

It was found that the home page could be set to a 'javascript:' link.
If a user were tricked into setting such a home page by dragging a link to the home button, it could cause Firefox to repeatedly crash, eventually leading to arbitrary code execution with the privileges of the user running Firefox. A similar flaw was found and fixed in Thunderbird. (CVE-2012-0458)

A flaw was found in the way Thunderbird parsed certain, remote content containing 'cssText'. Malicious, remote content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2012-0459)

It was found that by using the DOM fullscreen API, untrusted content could bypass the mozRequestFullscreen security protections. Malicious content could exploit this API flaw to cause user interface spoofing.
(CVE-2012-0460)

A flaw was found in the way Thunderbird handled content with multiple Content Security Policy (CSP) headers. This could lead to a cross-site scripting attack if used in conjunction with a website that has a header injection flaw. (CVE-2012-0451)

Note: All issues except CVE-2012-0456 and CVE-2012-0457 cannot be exploited by a specially crafted HTML mail message as JavaScript is disabled by default for mail messages. It could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed.

All Thunderbird users should upgrade to this updated package, which contains Thunderbird version 10.0.3 ESR, which corrects these issues.
After installing the update, Thunderbird must be restarted for the changes to take effect.

The remote Solaris system is missing necessary patches to address security updates :
