The version of Firefox installed on the remote Windows host is prior to 7.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2011-41 advisory.

  - Mozilla Firefox before 7.0 and SeaMonkey before 2.4 allow remote attackers to cause a denial of service     (application crash) or possibly execute arbitrary code via an unspecified WebGL test case that triggers a     memory-allocation error and a resulting out-of-bounds write operation. (CVE-2011-3003)

  - Almost Native Graphics Layer Engine (ANGLE), as used in Mozilla Firefox before 7.0 and SeaMonkey before     2.4, does not validate the return value of a GrowAtomTable function call, which allows remote attackers to     cause a denial of service (application crash) or possibly execute arbitrary code via vectors that trigger     a memory-allocation error and a resulting buffer overflow. (CVE-2011-3002)

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

Mozilla SeaMonkey was updated to version 2.4, fixing various bugs and security issues.

MFSA 2011-36: 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.

In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products.

Benjamin Smedberg, Bob Clary, and Jesse Ruderman reported memory safety problems that affected Firefox 3.6 and Firefox 6.
(CVE-2011-2995)

Bob Clary, Andrew McCreight, Andreas Gal, Gary Kwong, Igor Bukanov, Jason Orendorff, Jesse Ruderman, and Marcia Knous reported memory safety problems that affected Firefox 6, fixed in Firefox 7.
(CVE-2011-2997)

MFSA 2011-38: Mozilla developer Boris Zbarsky reported that a frame named 'location' could shadow the window.location object unless a script in a page grabbed a reference to the true object before the frame was created. Because some plugins use the value of window.location to determine the page origin this could fool the plugin into granting the plugin content access to another site or the local file system in violation of the Same Origin Policy. This flaw allows circumvention of the fix added for MFSA 2010-10.
(CVE-2011-2999)

MFSA 2011-39: Ian Graham of Citrix Online reported that when multiple Location headers were present in a redirect response Mozilla behavior differed from other browsers: Mozilla would use the second Location header while Chrome and Internet Explorer would use the first. Two copies of this header with different values could be a symptom of a CRLF injection attack against a vulnerable server. Most commonly it is the Location header itself that is vulnerable to the response splitting and therefore the copy preferred by Mozilla is more likely to be the malicious one. It is possible, however, that the first copy was the injected one depending on the nature of the server vulnerability.

The Mozilla browser engine has been changed to treat two copies of this header with different values as an error condition. The same has been done with the headers Content-Length and Content-Disposition.
(CVE-2011-3000)

MFSA 2011-40: Mariusz Mlynski reported that if you could convince a user to hold down the Enter key--as part of a game or test, perhaps--a malicious page could pop up a download dialog where the held key would then activate the default Open action. For some file types this would be merely annoying (the equivalent of a pop-up) but other file types have powerful scripting capabilities. And this would provide an avenue for an attacker to exploit a vulnerability in applications not normally exposed to potentially hostile internet content.

Mariusz also reported a similar flaw with manual plugin installation using the PLUGINSPAGE attribute. It was possible to create an internal error that suppressed a confirmation dialog, such that holding enter would lead to the installation of an arbitrary add-on. (This variant did not affect Firefox 3.6)

Holding enter allows arbitrary code execution due to Download Manager (CVE-2011-2372)

Holding enter allows arbitrary extension installation (CVE-2011-3001)

MFSA 2011-41: Michael Jordon of Context IS reported that in the ANGLE library used by WebGL the return value from GrowAtomTable() was not checked for errors. If an attacker could cause requests that exceeded the available memeory those would fail and potentially lead to a buffer overrun as subsequent code wrote into the non-allocated space.
(CVE-2011-3002)

Ben Hawkes of the Google Security Team reported a WebGL test case that demonstrated an out of bounds write after an allocation failed.
(CVE-2011-3003)

MFSA 2011-42: Security researcher Aki Helin reported a potentially exploitable crash in the YARR regular expression library used by JavaScript. (CVE-2011-3232)

MFSA 2011-43: David Rees reported that the JSSubScriptLoader (a feature used by some add-ons) was 'unwrapping' XPCNativeWrappers when they were used as the scope parameter to loadSubScript(). Without the protection of the wrappers the add-on could be vulnerable to privilege escalation attacks from malicious web content. Whether any given add-on were vulnerable would depend on how the add-on used the feature and whether it interacted directly with web content, but we did find at least one vulnerable add-on and presumer there are more.
(CVE-2011-3004)

The unwrapping behavior was a change introduced during Firefox 4 development. Firefox 3.6 and earlier versions are not affected.

MFSA 2011-44: sczimmer reported that Firefox crashed when loading a particular .ogg file. This was due to a use-after-free condition and could potentially be exploited to install malware. (CVE-2011-3005)

This vulnerability does not affect Firefox 3.6 or earlier.

MFSA 2011-45: University of California, Davis researchers Liang Cai and Hao Chen presented a paper at the 2011 USENIX HotSec workshop on inferring keystrokes from device motion data on mobile devices. Web pages can now receive data similar to the apps studied in that paper and likely present a similar risk. We have decided to limit motion data events to the currently-active tab to prevent the possibility of background tabs attempting to decipher keystrokes the user is entering into the foreground tab.

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

  - Mozilla Firefox before 3.6.23 and 4.x through 6,     Thunderbird before 7.0, and SeaMonkey before 2.4 do not     prevent the starting of a download in response to the     holding of the Enter key, which allows user-assisted     remote attackers to bypass intended access restrictions     via a crafted web site. (CVE-2011-2372)

  - Multiple unspecified vulnerabilities in the browser     engine in Mozilla Firefox before 3.6.23 and 4.x through     6, Thunderbird before 7.0, and SeaMonkey before 2.4     allow remote attackers to cause a denial of service     (memory corruption and application crash) or possibly     execute arbitrary code via unknown vectors.

(CVE-2011-3000)

  - Mozilla Firefox 4.x through 6, Thunderbird before 7.0,     and SeaMonkey before 2.4 do not prevent manual add-on     installation in response to the holding of the Enter     key, which allows user-assisted remote attackers to     bypass intended access restrictions via a crafted web     site that triggers an unspecified internal error.

  - The JSSubScriptLoader in Mozilla Firefox 4.x through 6     and SeaMonkey before 2.4 does not properly handle     XPCNativeWrappers during calls to the loadSubScript     method in an add-on, which makes it easier for remote     attackers to gain privileges via a crafted web site that     leverages certain unwrapping behavior. (CVE-2011-3004)

  - Use-after-free vulnerability in Mozilla Firefox 4.x     through 6, Thunderbird before 7.0, and SeaMonkey before     2.4 allows remote attackers to cause a denial of service     (application crash) or possibly execute arbitrary code     via crafted OGG headers in a .ogg file. (CVE-2011-3005)

  - YARR, as used in Mozilla Firefox before 7.0, Thunderbird     before 7.0, and SeaMonkey before 2.4, allows remote     attackers to cause a denial of service (application     crash) or possibly execute arbitrary code via crafted     JavaScript. (CVE-2011-3232)

  - Cross-site scripting (XSS) vulnerability in Mozilla     Firefox before 3.6.24 and 4.x through 7.0 and     Thunderbird before 3.1.6 and 5.0 through 7.0 allows     remote attackers to inject arbitrary web script or HTML     via crafted text with Shift JIS encoding.
    (CVE-2011-3648)

  - Mozilla Firefox before 3.6.24 and 4.x through 7.0 and     Thunderbird before 3.1.6 and 5.0 through 7.0 do not     properly handle JavaScript files that contain many     functions, which allows user-assisted remote attackers     to cause a denial of service (memory corruption and     application crash) or possibly have unspecified other     impact via a crafted file that is accessed by debugging     APIs, as demonstrated by Firebug. (CVE-2011-3650)

  - Multiple unspecified vulnerabilities in the browser     engine in Mozilla Firefox 7.0 and Thunderbird 7.0 allow     remote attackers to cause a denial of service (memory     corruption and application crash) or possibly execute     arbitrary code via unknown vectors. (CVE-2011-3651)

  - The browser engine in Mozilla Firefox before 8.0 and     Thunderbird before 8.0 does not properly allocate     memory, which allows remote attackers to cause a denial     of service (memory corruption and application crash) or     possibly execute arbitrary code via unspecified vectors.
    (CVE-2011-3652)

  - The browser engine in Mozilla Firefox before 8.0 and     Thunderbird before 8.0 does not properly handle links     from SVG mpath elements to non-SVG elements, which     allows remote attackers to cause a denial of service     (memory corruption and application crash) or possibly     execute arbitrary code via unspecified vectors.
    (CVE-2011-3654)

  - Mozilla Firefox 4.x through 7.0 and Thunderbird 5.0     through 7.0 perform access control without checking for     use of the NoWaiverWrapper wrapper, which allows remote     attackers to gain privileges via a crafted web site.

The remote host is affected by the vulnerability described in GLSA-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.

The installed version of Firefox is earlier than 7.0 and thus, is potentially affected by the following security issues :

  - If an attacker could trick a user into holding down the     'Enter' key, via a malicious game, for example, a     malicious application or extension could be downloaded     and executed.(CVE-2011-2372, CVE-2011-3001)

  - Unspecified errors exist that can be exploited to     corrupt memory. No additional information is available     at this time. (CVE-2011-2995, CVE-2011-2997)

  - A weakness exists when handling the 'Location' header.     This can lead to response splitting attacks when     visiting a vulnerable web server. The same fix has been     applied to the headers 'Content-Length' and     'Content-Disposition'. (CVE-2011-3000)

  - An error exists within WebGL's ANGLE library. It does     not properly check for return values from the     'GrowAtomTable()' function. This vulnerability can be     exploited to cause a buffer overflow by sending a     series of requests. Additionally, an unspecified error     exists within WebGL that can be exploited to corrupt     memory. (CVE-2011-3002, CVE-2011-3003)

  - There is an error within the JSSubScriptLoader that     incorrectly unwraps 'XPCNativeWrappers'. By tricking     a user into installing a malicious plug-in, an attacker     could exploit this issue to execute arbitrary code.     (CVE-2011-3004)

  - A use-after-free error exists when parsing OGG headers.     (CVE-2011-3005)

  - There is an unspecified error within the YARR regular     expression library that can be exploited to corrupt     memory. (CVE-2011-3232)

USN-1222-1 fixed vulnerabilities in Firefox. This update provides updated packages for use with Firefox 7.

Benjamin Smedberg, Bob Clary, Jesse Ruderman, Bob Clary, Andrew McCreight, Andreas Gal, Gary Kwong, Igor Bukanov, Jason Orendorff, Jesse Ruderman, and Marcia Knous discovered multiple memory vulnerabilities in the browser rendering engine. An attacker could use these to possibly execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2995, CVE-2011-2997)

Boris Zbarsky discovered that a frame named 'location' could shadow the window.location object unless a script in a page grabbed a reference to the true object before the frame was created. This is in violation of the Same Origin Policy. A malicious website could possibly use this to access another website or the local file system. (CVE-2011-2999)

Ian Graham discovered that when multiple Location headers were present, Firefox would use the second one resulting in a possible CRLF injection attack. CRLF injection issues can result in a wide variety of attacks, such as XSS (Cross-Site Scripting) vulnerabilities, browser cache poisoning, and cookie theft. (CVE-2011-3000)

Mariusz Mlynski discovered that if the user could be convinced to hold down the enter key, a malicious website could potential pop up a download dialog and the default open action would be selected or lead to the installation of an arbitrary add-on. This would result in potentially malicious content being run with privileges of the user invoking Firefox. (CVE-2011-2372, CVE-2011-3001)

Michael Jordon and Ben Hawkes discovered flaws in WebGL. If a user were tricked into opening a malicious page, an attacker could cause the browser to crash. (CVE-2011-3002, CVE-2011-3003)

It was discovered that Firefox did not properly free memory when processing ogg files. If a user were tricked into opening a malicious page, an attacker could cause the browser to crash. (CVE-2011-3005)

David Rees and Aki Helin discovered a problems in the JavaScript engine. An attacker could exploit this to crash the browser or potentially escalate privileges within the browser. (CVE-2011-3232).

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.
