Ubuntu Security Notice USN-1122-3
June 06, 2011

thunderbird regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04

Summary:

An empty menu bar sometimes appeared after upgrade in USN-1122-2

Software Description:
- thunderbird: mail/news client with RSS and integrated spam filter support

Details:

USN-1122-2 fixed vulnerabilities in Thunderbird on Ubuntu 11.04. A
regression was introduced which caused Thunderbird to display an empty menu
bar. This update fixes the problem. We apologize for the inconvenience.

Original advisory details:

 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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.04:
  thunderbird-globalmenu          3.1.10+build1+nobinonly-0ubuntu0.11.04.2

After a standard system update you need to restart Thunderbird to make
all the necessary changes.
