Critical: seamonkey security update

Updated seamonkey packages that fix several security issues are now
available for Red Hat Enterprise Linux 2.1, 3, and 4.

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

SeaMonkey is an open source Web browser, advanced email and newsgroup
client, IRC chat client, and HTML editor.

Several flaws were found in the way SeaMonkey processed certain malformed
web content. A webpage containing malicious content could cause SeaMonkey
to crash, or potentially execute arbitrary code as the user running
SeaMonkey. (CVE-2008-0412, CVE-2008-0413, CVE-2008-0415, CVE-2008-0419)

Several flaws were found in the way SeaMonkey displayed malformed web
content. A webpage containing specially-crafted content could trick a user
into surrendering sensitive information. (CVE-2008-0591, CVE-2008-0593)

A flaw was found in the way SeaMonkey stored password data. If a user
saves login information for a malicious website, it could be possible
to corrupt the password database, preventing the user from properly
accessing saved password data. (CVE-2008-0417)

A flaw was found in the way SeaMonkey handles certain chrome URLs. If a
user has certain extensions installed, it could allow a malicious website
to steal sensitive session data. Note: this flaw does not affect a default
installation of SeaMonkey. (CVE-2008-0418)

A flaw was found in the way SeaMonkey saves certain text files. If a
website offers a file of type "plain/text", rather than "text/plain",
SeaMonkey will not show future "text/plain" content to the user in the
browser, forcing them to save those files locally to view the content.
(CVE-2008-0592)

Users of SeaMonkey are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.

Before applying this update, make sure that all previously-released
