Synopsis :

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

Description :

Updated SeaMonkey packages that fix several security bugs are now
available for Red Hat Enterprise Linux 2.1, 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, advanced email and newsgroup
client, IRC chat client, and HTML editor.

Two flaws were found in the way SeaMonkey processed certain regular
expressions. A malicious web page could crash the browser or possibly
execute arbitrary code as the user running SeaMonkey. (CVE-2006-4565,
CVE-2006-4566)

A flaw was found in the handling of JavaScript timed events. A
malicious web page could crash the browser or possibly execute
arbitrary code as the user running SeaMonkey. (CVE-2006-4253)

Daniel Bleichenbacher recently described an implementation error in
RSA signature verification. For RSA keys with exponent 3 it is
possible for an attacker to forge a signature that would be
incorrectly verified by the NSS library. SeaMonkey as shipped trusts
several root Certificate Authorities that use exponent 3. An attacker
could have created a carefully crafted SSL certificate which be
incorrectly trusted when their site was visited by a victim.
(CVE-2006-4340)

SeaMonkey did not properly prevent a frame in one domain from
injecting content into a sub-frame that belongs to another domain,
which facilitates website spoofing and other attacks (CVE-2006-4568)

A flaw was found in SeaMonkey Messenger triggered when a HTML message
contained a remote image pointing to a XBL script. An attacker could
have created a carefully crafted message which would execute
JavaScript if certain actions were performed on the email by the
recipient, even if JavaScript was disabled. (CVE-2006-4570)

A number of flaws were found in SeaMonkey. A malicious web page could
crash the browser or possibly execute arbitrary code as the user
running SeaMonkey. (CVE-2006-4571)

Users of SeaMonkey or Mozilla are advised to upgrade to this update,
which contains SeaMonkey version 1.0.5 that corrects these issues.

For users of Red Hat Enterprise Linux 2.1 this SeaMonkey update
obsoletes Galeon. Galeon was a web browser based on the Mozilla Gecko
layout engine.
