A security issue affects these releases of Ubuntu and its derivatives:
Thunderbird could be made to run programs as your login if it opened specially crafted mail.
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)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to restart Thunderbird to make all the necessary changes.
