1. Summary:

Updated thunderbird packages that fix several security bugs are now
available for Red Hat Enterprise Linux 4.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

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
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/):

219686 - CVE-2006-6497 Multiple Thunderbird issues (CVE-2006-6498, CVE-2006-6501, CVE-2006-6502, CVE-2006-6503, CVE-2006-6504, CVE-2006-6505)
