Synopsis: Critical: seamonkey security update

CVE Numbers: CVE-2011-2999
 CVE-2011-2998

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

A flaw was found in the way SeaMonkey handled frame objects with certain
names. An attacker could use this flaw to cause a plug-in to grant its
content access to another site or the local file system, violating the
same-origin policy. (CVE-2011-2999)

An integer underflow flaw was found in the way SeaMonkey handled large
JavaScript regular expressions. A web page containing malicious
JavaScript could cause SeaMonkey to access already freed memory, causing
SeaMonkey to crash or, potentially, execute arbitrary code with the
privileges of the user running SeaMonkey. (CVE-2011-2998)

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.
