Hat Security Response Team.

Description

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

A use-after-free flaw was found in SeaMonkey. Under low memory conditions,
visiting a web page containing malicious content could result in SeaMonkey
executing arbitrary code with the privileges of the user running SeaMonkey.
(CVE-2009-1571)

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-2010-0159)

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.
