Synopsis

Critical: seamonkey security update

Type/Severity

Security Advisory: Critical

Topic

Updated seamonkey packages that fix several security issues are now
available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

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-2009-3979)

A flaw was found in the SeaMonkey NT Lan Manager (NTLM) authentication
protocol implementation. If an attacker could trick a local user that has
NTLM credentials into visiting a specially-crafted web page, they could
send arbitrary requests, authenticated with the user's NTLM credentials, to
other applications on the user's system. (CVE-2009-3983)

A flaw was found in the way SeaMonkey displayed the SSL location bar
indicator. An attacker could create an unencrypted web page that appears
to be encrypted, possibly tricking the user into believing they are
visiting a secure page. (CVE-2009-3984)

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.
