seamonkey security update

CentOS Errata and Security Advisory CESA-2009:0437-02

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

Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause SeaMonkey to crash or,
potentially, execute arbitrary code as the user running SeaMonkey.
(CVE-2009-1303, CVE-2009-1305)

Several flaws were found in the way malformed web content was processed. A
web page containing malicious content could execute arbitrary JavaScript in
the context of the site, possibly presenting misleading data to a user, or
stealing sensitive information such as login credentials. (CVE-2009-0652,
CVE-2009-1306, CVE-2009-1307, CVE-2009-1309, CVE-2009-1312)

A flaw was found in the way SeaMonkey saved certain web pages to a local
file. If a user saved the inner frame of a web page containing POST data,
the POST data could be revealed to the inner frame, possibly surrendering
sensitive information such as login credentials. (CVE-2009-1311)

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