(RHSA-2009:1134) Important: seamonkey security update

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

A flaw was found in the way that SeaMonkey parsed malformed HTML mail
messages. If a user opened a specially-crafted HTML mail message, it could
cause SeaMonkey to crash or, possibly, to execute arbitrary code as the
user running SeaMonkey. (CVE-2009-2210)

All SeaMonkey users should upgrade to these updated packages, which correct
this issue. After installing the update, SeaMonkey must be restarted for
the changes to take effect.
