seamonkey security update

CentOS Errata and Security Advisory CESA-2012:0084

SeaMonkey is an open source web browser, e-mail and newsgroup client, IRC
chat client, and HTML editor.

A flaw was found in the processing of malformed web content. A web page
containing malicious content could cause SeaMonkey to crash or,
potentially, execute arbitrary code with the privileges of the user running
SeaMonkey. (CVE-2012-0442)

The same-origin policy in SeaMonkey treated http://example.com and
http://[example.com] as interchangeable. A malicious script could possibly
use this flaw to gain access to sensitive information (such as a client’s
IP and user e-mail address, or httpOnly cookies) that may be included in
HTTP proxy error replies, generated in response to invalid URLs using
square brackets. (CVE-2011-3670)

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.
