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.
