3. Problem description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the way Thunderbird processes certain malformed
Javascript code. A malicious web page could cause the execution of
Javascript code in such a way that could cause Thunderbird to crash or
execute arbitrary code as the user running Thunderbird.  JavaScript support
is disabled by default in Thunderbird; this issue is not exploitable
without enabling JavaScript. (CVE-2006-6498, CVE-2006-6501, CVE-2006-6502,
CVE-2006-6503, CVE-2006-6504)

Several flaws were found in the way Thunderbird renders web pages. A
malicious web page could cause the browser to crash or possibly execute
arbitrary code as the user running Thunderbird. (CVE-2006-6497)

A heap based buffer overflow flaw was found in the way Thunderbird parses
the Content-Type mail header. A malicious mail message could cause the
Thunderbird client to crash or possibly execute arbitrary code as the user
running Thunderbird. (CVE-2006-6505) 

Users of Thunderbird are advised to apply this update, which contains
Thunderbird version 1.5.0.9 that corrects these issues.

4. Solution:

Before applying this update, make sure all previously released errata
