Ubuntu Several security issues were fixed in Thunderbird.
==========================================================================
Ubuntu Security Notice USN-1401-2
March 23, 2012

thunderbird vulnerabilities
==========================================================================

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

- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

Software Description:
- thunderbird: Mozilla Open Source mail and newsgroup client

Details:

USN-1401-1 fixed vulnerabilities in Xulrunner. This update provides the
corresponding fixes for Thunderbird.

Original advisory details:

 It was discovered that a flaw in the Mozilla SVG implementation could
 result in an out-of-bounds memory access if SVG elements were removed
 during a DOMAttrModified event handler. If the user were tricked into
 opening a specially crafted page, an attacker could exploit this to cause a
 denial of service via application crash. (CVE-2011-3658)
 
 Atte Kettunen discovered a use-after-free vulnerability in the Gecko
 Rendering Engine's handling of SVG animations. An attacker could
 potentially exploit this to execute arbitrary code with the privileges of
 the user invoking the Xulrunner based application. (CVE-2012-0457)
  
 Atte Kettunen discovered an out of bounds read vulnerability in the Gecko
 Rendering Engine'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)
 
 Soroush Dalili discovered that the Gecko Rendering Engine 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 of the frame or steal confidential data. (CVE-2012-0455)
 
 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)
 
 Bob Clary, 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-2012-0464)

Update instructions:

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

Ubuntu 11.04:
  thunderbird                     3.1.20+build1+nobinonly-0ubuntu0.11.04.1

Ubuntu 10.10:
  thunderbird                     3.1.20+build1+nobinonly-0ubuntu0.10.10.1

Ubuntu 10.04 LTS:
  thunderbird                     3.1.20+build1+nobinonly-0ubuntu0.10.04.1

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