mozilla-thunderbird - several

Several security-related problems have been discovered in Mozilla and
derived programs. Some of the following problems don’t exactly apply
to Mozilla Thunderbird, even though the code is present. In order to
keep the codebase in sync with upstream it has been altered
nevertheless. The Common Vulnerabilities and Exposures project
identifies the following problems:

• CAN-2005-2871
  Tom Ferris discovered a bug in the IDN hostname handling of
  Mozilla that allows remote attackers to cause a denial of service
  and possibly execute arbitrary code via a hostname with dashes.
• CAN-2005-2701
  A buffer overflow allows remote attackers to execute arbitrary
  code via an XBM image file that ends in a large number of spaces
  instead of the expected end tag.
• CAN-2005-2702
  Mats Palmgren discovered a buffer overflow in the Unicode string
  parser that allows a specially crafted Unicode sequence to
  overflow a buffer and cause arbitrary code to be executed.
• CAN-2005-2703
  Remote attackers could spoof HTTP headers of XML HTTP requests
  via XMLHttpRequest and possibly use the client to exploit
  vulnerabilities in servers or proxies.
• CAN-2005-2704
  Remote attackers could spoof DOM objects via an XBL control that
  implements an internal XPCOM interface.
• CAN-2005-2705
  Georgi Guninski discovered an integer overflow in the JavaScript
  engine that might allow remote attackers to execute arbitrary
  code.
• CAN-2005-2706
  Remote attackers could execute Javascript code with chrome
  privileges via an about: page such as about:mozilla.
• CAN-2005-2707
  Remote attackers could spawn windows without user interface
  components such as the address and status bar that could be used
  to conduct spoofing or phishing attacks.
• CAN-2005-2968
  Peter Zelezny discovered that shell metacharacters are not
  properly escaped when they are passed to a shell script and allow
  the execution of arbitrary commands, e.g. when a malicious URL is
  automatically copied from another program into Mozilla as default
  browser.

For the stable distribution (sarge) these problems have been fixed in
version 1.0.2-2.sarge1.0.7.

For the unstable distribution (sid) these problems have been fixed in
version 1.0.7-1.

We recommend that you upgrade your mozilla-thunderbird package.
