RHEL 3 / 4 : seamonkey (RHSA-2009:1673)

High Nessus Plugin ID 43170


The remote Red Hat host is missing one or more security updates.


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.

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.

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.


Update the affected packages.
