Mozilla Firefox was updated to the 3.6.17 security release.

MFSA 2011-12: 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. Credits

Mozilla developer Scoobidiver reported a memory safety issue which affected Firefox 4 and Firefox 3.6 (CVE-2011-0081)

The web development team of Alcidion reported a crash that affected Firefox 4, Firefox 3.6 and Firefox 3.5. (CVE-2011-0069)

Ian Beer reported a crash that affected Firefox 4, Firefox 3.6 and Firefox 3.5. (CVE-2011-0070)

Mozilla developers Bob Clary, Henri Sivonen, Marco Bonardo, Mats Palmgren and Jesse Ruderman reported memory safety issues which affected Firefox 3.6 and Firefox 3.5. (CVE-2011-0080)

Aki Helin reported memory safety issues which affected Firefox 3.6 and Firefox 3.5. (CVE-2011-0074 , CVE-2011-0075)

Ian Beer reported memory safety issues which affected Firefox 3.6 and Firefox 3.5. (CVE-2011-0077 , CVE-2011-0078)

Martin Barbella reported a memory safety issue which affected Firefox 3.6 and Firefox 3.5. (CVE-2011-0072)

MFSA 2011-13 / CVE-2011-0065 / CVE-2011-0066 / CVE-2011-0073: Security researcher regenrecht reported several dangling pointer vulnerabilities via TippingPoint's Zero Day Initiative.

MFSA 2011-14 / CVE-2011-0067: Security researcher Paul Stone reported that a Java applet could be used to mimic interaction with form autocomplete controls and steal entries from the form history.

MFSA 2011-15 / CVE-2011-0076: David Remahl of Apple Product Security reported that the Java Embedding Plugin (JEP) shipped with the Mac OS X versions of Firefox could be exploited to obtain elevated access to resources on a user's system.

MFSA 2011-16 / CVE-2011-0071: Security researcher Soroush Dalili reported that the resource: protocol could be exploited to allow directory traversal on Windows and the potential loading of resources from non-permitted locations. The impact would depend on whether interesting files existed in predictable locations in a useful format.
For example, the existence or non-existence of particular images might indicate whether certain software was installed. 

MFSA 2011-18 / CVE-2011-1202: Chris Evans of the Chrome Security Team reported that the XSLT generate-id() function returned a string that revealed a specific valid address of an object on the memory heap. It is possible that in some cases this address would be valuable information that could be used by an attacker while exploiting a different memory corruption but, in order to make an exploit more reliable or work around mitigation features in the browser or operating system.

USN-1122-1 fixed vulnerabilities in Thunderbird for Lucid and Maverick. This update provides the corresponding fixes for Natty.

It was discovered that there was a vulnerability in the memory handling of certain types of content. An attacker could exploit this to possibly run arbitrary code as the user running Thunderbird.
(CVE-2011-0081)

It was discovered that Thunderbird incorrectly handled certain JavaScript requests. If JavaScript were enabled, an attacker could exploit this to possibly run arbitrary code as the user running Thunderbird. (CVE-2011-0069)

Ian Beer discovered a vulnerability in the memory handling of a certain types of documents. An attacker could exploit this to possibly run arbitrary code as the user running Thunderbird. (CVE-2011-0070)

Bob Clary, Henri Sivonen, Marco Bonardo, Mats Palmgren and Jesse Ruderman discovered several memory vulnerabilities. An attacker could exploit these to possibly run arbitrary code as the user running Thunderbird. (CVE-2011-0080)

Aki Helin discovered multiple vulnerabilities in the HTML rendering code. An attacker could exploit these to possibly run arbitrary code as the user running Thunderbird.
(CVE-2011-0074, CVE-2011-0075)

Ian Beer discovered multiple overflow vulnerabilities. An attacker could exploit these to possibly run arbitrary code as the user running Thunderbird. (CVE-2011-0077, CVE-2011-0078)

Martin Barbella discovered a memory vulnerability in the handling of certain DOM elements. An attacker could exploit this to possibly run arbitrary code as the user running Thunderbird. (CVE-2011-0072)

It was discovered that there were use-after-free vulnerabilities in Thunderbird's mChannel and mObserverList objects. An attacker could exploit these to possibly run arbitrary code as the user running Thunderbird.
(CVE-2011-0065, CVE-2011-0066)

It was discovered that there was a vulnerability in the handling of the nsTreeSelection element. An attacker sending a specially crafted E-Mail could exploit this to possibly run arbitrary code as the user running Thunderbird.
(CVE-2011-0073)

Paul Stone discovered a vulnerability in the handling of Java applets. If plugins were enabled, an attacker could use this to mimic interaction with form autocomplete controls and steal entries from the form history. (CVE-2011-0067)

Soroush Dalili discovered a vulnerability in the resource:
protocol. This could potentially allow an attacker to load arbitrary files that were accessible to the user running Thunderbird. (CVE-2011-0071)

Chris Evans discovered a vulnerability in Thunderbird's XSLT generate-id() function. An attacker could possibly use this vulnerability to make other attacks more reliable.
(CVE-2011-1202).

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.

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.
