Updated thunderbird packages that fix several security bugs are now
available for Red Hat Enterprise Linux 4 and 5.

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

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the way Thunderbird processed certain malformed
JavaScript code. A web page containing malicious JavaScript code could
cause Thunderbird to crash or potentially execute arbitrary code
as the user running Thunderbird. (CVE-2007-2867, CVE-2007-2868)

Several denial of service flaws were found in the way Thunderbird handled
certain form and cookie data. A malicious web site that is able to set
arbitrary form and cookie data could prevent Thunderbird from
functioning properly. (CVE-2007-1362, CVE-2007-2869)

A flaw was found in the way Thunderbird processed certain APOP
authentication requests. By sending certain responses when Thunderbird
attempted to authenticate against an APOP server, a remote attacker could
potentially acquire certain portions of a user's authentication
credentials. (CVE-2007-1558)

A flaw was found in the way Thunderbird displayed certain web content. A
malicious web page could generate content which could overlay user
interface elements such as the hostname and security indicators, tricking
users into thinking they are visiting a different site. (CVE-2007-2871)

Users of Thunderbird are advised to apply this update, which contains
Thunderbird version 1.5.0.12 that corrects these issues.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
