Synopsis :

The remote Windows host contains a mail client that is affected by
multiple vulnerabilities.

Description :

The installed version of Thunderbird is earlier than 2.0.0.21. Such
versions are potentially affected by the following security issues :

- There are several stability bugs in the browser engine
that could lead to crashes with evidence of memory
corruption. (MFSA 2009-01)

- By exploiting stability bugs in the browser engine, it
might be possible for an attacker to execute arbitrary
code on the remote system under certain conditions.
(MFSA 2009-07)

- It might be possible for a website to read arbitrary XML
data from another domain by using nsIRDFService and a
cross-domain redirect. (MFSA 2009-09)

- Vulnerabilities in the PNG libraries used by Mozilla
could be exploited to execute arbitrary code on the
remote system. (MFSA 2009-10)

- A URI-spoofing vulnerability exists because the
application fails to adequately handle specific
characters in IDN subdomains. (MFSA 2009-15)
