Description

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 with the privileges of the user running
SeaMonkey. (CVE-2010-3767, CVE-2010-3772, CVE-2010-3776)

A flaw was found in the way SeaMonkey loaded Java LiveConnect scripts.
Malicious web content could load a Java LiveConnect script in a way that
would result in the plug-in object having elevated privileges, allowing it
to execute Java code with the privileges of the user running SeaMonkey.
(CVE-2010-3775)

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.
